The main visual difference between the two motorcycles of the IZH family is the number of engine cylinders. The Jupiter 5 model has two of them, while the Planet 5 has only one.
In all other respects, the models are maximally unified with each other, with the exception of electrical components.
For reference: another design feature of the IZH Jupiter of the last 5 years of production is the use of water cooling.
And Planet 5 has all air-cooled engines.
Despite the unification of parts with other models, the IZH Yu5 wiring diagram was selected for battery use..
We are talking about a contact ignition system, which, with a “dead” battery, immediately creates problems for the owner:
- Starting the engine is difficult;
- The engine runs intermittently;
- Driving at low speeds further drains the battery.
For reference: unlike the Jupiter model, a new wiring and an electronic ignition system were installed on the modified IZH Planet 5.
The methods proposed below are just designed for simplified work - not requiring a major replacement of components.
Transition to contactless ignition system
But there is a more advanced way, in which:
- The generator and wiring on IZH Jupiter 5 remain;
- Minor alterations are made to the electrical circuit;
- The battery is left to service auxiliary systems.
We are talking about the modernization of the ignition system with the combined use of elements from the VAZ-2108 car and the Planet 5 motorcycle.
At the same time, the wiring diagram for IZH Jupiter 5 is preserved:
- Two Hall sensors are installed;
- Two electronic switches are connected to them (points 1 and 2 - with VAZ). Each pair of sensor-commutator services 1 cylinder;
- Two ignition coils from a motorcycle of the IZH family.
In the diagram above, the numbers indicate:
- Spark plug;
- Coils Planet 5;
- Switches from the "eight";
- Hall sensors from the "eight";
- Egnition lock;
- Accumulator battery.
Refinement of the generator
This technology for switching to a contactless ignition system is interesting in that the motorcycle owner does not need to buy a new generator designed to work in an electronic ignition system. Accordingly, the cost of alteration will be minimal.
Enough:
- Make a modulator that will interrupt the circuit;
- And install it on the generator (on the rotor shaft).
A metal plate with a hole drilled in it for a mounting bolt can serve as such a modulator-interrupter.
The order of installation of the modulator is as follows:
- The modulator plate (in the diagram below under No. 2) is installed under the mounting bolt;
- Slightly attracted to him;
- By rotating the crankshaft, set the piston to TDC;
- We set the ignition timing;
- Tighten the plate with the fixing bolt.
For reference: in addition to the modulator, it is installed under the engine cover and two Hall sensors (in diagram No. 1). There are places to mount them.
Improvement of the regular system
For those owners who do not want to switch to a contactless ignition system, there are other ways to improve sparking.
At the same time, the wiring of the IZH Jupiter 5 motorcycle is analyzed for problem areas, and most often:
- The primary circuit from the battery to the coil is diagnosed;
- Places of voltage drop caused by operating conditions are identified.
A simple inspection of the primary circuit will demonstrate several problem areas at once:
- four plug connectors;
- emergency ignition switch;
- contacts of the central switch;
- interrupter contacts.
Under ideal operating conditions, such a complex section of the chain will work flawlessly.
But in practice, it is exposed to dirt dust flying from under the wheels, therefore, in the circuit due to an increase in resistance at the points of contact:
- the voltage decreases from 12 V to 7-8 V;
- this is not enough to excite a powerful discharge of the secondary winding of the coil;
- as a result - a low discharge on the candle, making it difficult to ignite the combustible mixture in the cylinders.
And if we add to this a “dead” battery and oily candles with burnt contacts, then the process of sparking becomes completely problematic.
Motorcyclists solve such defects as follows:
- traditional soldering. The wiring on IZH Yu5 gets rid of plug connections and each wiring is tritely soldered by hand, followed by insulation;
- installation of an additional toggle switch (in diagram No. 1), which turns off all consumers at the time of starting the engine. This allows you to apply the maximum voltage from the battery to the coil;
- alteration of the ignition lock. A wire is soldered to the free connector of lock 4 (in diagram No. 2), the second end of which is fed to the positive terminal of the coil.
The standard ignition wire from terminal 5 is transferred to terminal 6, and when this key position is activated, a simplified scheme for supplying power from the battery to the primary circuit of the coil is activated.
Conclusions: you can learn from this article not only proven ways to improve the electrical part of a motorcycle (as in the article about), but also watch video materials that clearly demonstrate the modernization work algorithm.

Installation of BSZ on Izh Jupiter-5: advantages of the system
Installing a contactless ignition system on Izh Jupiter-5 is a fairly relevant topic. When establishing a BSZ on Izh Jupiter-5 BSZ, it is necessary to take into account a number of nuances that can significantly affect the operation of the equipment used.
What advantages open up to users who decide to install electronic ignition on Izh Jupiter are described below.
Most modern motorcycles are not equipped with cams, that is, breakers. Why did the manufacturer consider them unnecessary for currently sold models? The answer is simple enough. This system is not very reliable.
Many parts used in the system are sources of trouble. The most common ones are listed below:
- Ignition gaps change their initial position during driving a few days after adjustment;
- A spark occurs every other time, as the contacts regularly burn out;
- Constantly there are beatings of capacitors;
- Small spark power;
- When replanting the battery by two or three volts, it is quite difficult to start it. Such ignition is the cause of constant repair while driving.
Many mistakenly believe that it is very difficult to introduce a BSZ scoop on Izh Jupiter 5. As a rule, it takes more time to purchase the necessary spare parts than to install a BSZ on an izh. Of course, after implantation, performance changes significantly in the best direction.
This is noticeable at idle. The speed of their passage has noticeably increased and unnatural jerks have disappeared. The characteristic knocks of iron components in the crankcase and accompanying detonations also disappeared. The handling of the Jupiter 5 motorcycle will improve along with the acceleration time.
Required Parts
In order for the ignition system to work correctly, a number of auxiliary parts will be required. They are listed below:
- Switch for BSZ cars of the VAZ brand. Do not choose exclusively from the low price segment. The Astro switch has a lot of positive feedback;
- Hall Sensor. The best option for Jupiter 5 is a similar manufacturer of VAZ. By purchasing it in branded packaging, you protect yourself from fakes;
- Ignition reel with two leads. You should choose between a gazelle engine number 406 or Okoy with an electronic ignition system;
- A pair of silicone armor wires with rubber caps;
- The modulator is a butterfly-shaped plate made of iron.
Modulator
The most difficult stage is the production of the modulator. It is important to keep the necessary form. The more reliably the required dimensions are observed, the lower the likelihood of malfunctions after the implementation of the system, that is, there will be no need to correct it with a file. The ignition timing must match on any cylinder used.
The bolt hole must be located in the middle. Otherwise, the engine will run out of sync. It is also recommended to check the integrity of the crankshaft bearings. If you find defects, you should immediately replace it.
Contact ignition is not able to work normally with dead bearings. The thickness of the part should not exceed one and a half millimeters. If it is thin, then it will not be possible to avoid deformation, and the thick one is in contact with the surface of the hall sensor housing.
To create a plate, it is allowed to use any material except steel. Aluminum and others should not be used as they are not magnetic. The drawing to be followed can be found in the public domain. The presented scheme will be useful to those who decide to upgrade the ignition device of the vehicle. The following are methods for installing electrical ignition devices in Jupiter.
It must be turned by a professional turner. He will make a simple disk and draw on it the markup of the elementary distances between the corners. After that, in accordance with it, you will cut out the necessary sectors at home. The cost of the modulator is seventy rubles.
It is impractical to use an ordinary plate, since its width is less than twelve millimeters. This will not be enough for the full accumulation of the energy resource in the coil. Of course, it can be installed, but reaching four thousand revolutions per minute will become impossible.
In addition to the above, you will need:
- A threaded stud of seven millimeters step 1, as well as a pair of nuts with washers of the appropriate parameters. The preferred material for these components is brass. This is due to the least magnetization of the plate from the generator rotor.
If you use a regular bolt, then there may be difficulties with the introduction of ignition. The bolt tends to follow the modulator when twisting. However, it is necessary to observe the leading indicator, maintain the same position of the rotor and modulator, tighten the bolt. It is advisable to use a hairpin, since many are not able to perform all the necessary actions in the aggregate;
- A set of wires with connectors for ignition without contact from VAZ. This part can be purchased or made with your own hands.
Collection and installation of the system
The contacts in the interrupter, the capacitor, the ignition coils and armored wires, which are a part of the former ignition device, are probably eliminated. The switch should embed the glove compartment on the right, and the ignition coil directly under the tank. There are no gaps on the coil for fastening, which means that it can be attached using a massive layer of adhesive tape. The standard bolt is also abolished with other parts.
In place of the bolt, install a stud of a given size and put on a washer. Then, the rotor is twisted with a nut located at its end. The hall sensor is attached to the stator by any means. The main rule when installing it is to set the optimal distance of the modulator section and the ratio of the radius and the line of symmetry.
When the hall sensor can be fixed, we impose a modulator. It should fall into the hole made in the sensor. In most situations, there is a mismatch in size, so it is necessary to put washers on the stud. If it was possible to maintain the required clearance, then it is recommended to install the engraver and tighten the modulator with a third-party nut.
Final actions
Rubber caps should be put on armor wires, and the latter should be inserted into candlesticks or a coil. If you skip this step, the motorcycle will stall when riding in rainy weather, as moisture will get into the battery.
When introducing candles into the tip, it will be possible to maintain excellent contact between the battery and the volume of the vehicle. Now you will need a pre-purchased set of wires. The commutator, coil and hall sensor are connected by wiring. She needs to be isolated. Of the whole mass, only a common plus is required.
Setting suitable parameters
Setting the BSZ on Izh Jupiter 5 also requires special attention. The ignition is switched on with the tachometer connected. After thirty seconds, indicators of 3000, 4000, 5000 rpm should appear on the device panel. If they are, then the switch is working properly.
In other cases, you should pay attention to previously grounded candles. We insert a screwdriver into the hall connector, and then pull it out. A spark should appear on the candles. If it was not possible to cause a spark by the above actions, then the reason for incorrect operation is incorrect connections.
The setup looks like this. The dial indicator is unscrewed and the cylinder piston is adjusted. Having connected the voltmeter to the second and third connectors, it is necessary to start rotating the modulator axis. After a jump from 7 to 0.1 volts is detected, the modulator must be secured with a nut. Usually set the required lead angle.
The test run should be successful if the components are installed by hand in accordance with the instructions. Now you can use BSZ.

IZH Jupiter 5 and its electrical equipment: briefly about the main
Unlike similar models of Soviet-era motorcycles, the electrical wiring diagram of the IZH Jupiter 5 motorcycle provides for operation from a battery with air-cooled equipment. This causes a lot of problems for the owners. The article gives recommendations for modernization that solves the problem of sparking.
IZH motorcycle models are unified as much as possible. The IZH Jupiter 2 wiring diagram is not much different from the later versions of the IZH motorcycle. There are external differences. For example, the Planet 5 bike has one cylinder, while the Jupiter 5 has two.
The first 12 volt motorcycle was IZH Jupiter 4. The wiring diagram of IZH Jupiter 5 and the wiring diagram of IZH Jupiter 3 differ in components.
Wiring diagram IZH Jupiter 5 On the bike of the fifth Jupiter there is a contact SZ, which runs on battery power, so the operation of the vehicle is highly dependent on the degree of battery charge.
If the charge is insufficient, then the following problems occur:
- the motor works intermittently;
- the engine starts with difficulty;
- battery drains at low speed.
You can fix these problems by switching to BSZ. Any electrician will cope with this task (the author of the video is Viter Electronic).
How to make the transition to contactless SZ?
To switch to contactless SZ, motorists use parts from other motorcycle models. When upgrading the generator set and wiring IZH Jupiter 5 remain unchanged. Minor alterations relate to the electrical circuit of the IZH. The battery after the changes is used to service auxiliary equipment. To switch to BSZ, parts are taken from Planet 5 and a VAZ 2108 car.
The following changes are made to the IZH electrical circuit:
- install 2 Hall sensors from the eighth VAZ model;
- 2 VAZ electronic switches must be connected to the sensors;
- each of the cylinders serves a pair of switch-sensor;
- two more ignition coils must be added to the circuit.
SZ after modernization On the electrical circuit of the IZH motorcycle, the components are marked with numbers:
- Spark plug.
- Ignition coils from Planet 5.
- Switches.
- Hall sensors.
- Egnition lock.
- Battery.
For the created ignition system, it is necessary to modify the IZH Jupiter 5 generator, the circuit of which will not require major changes.
How can the generator be improved?
The presented upgrade option is beneficial in that it does not require the purchase of a new generator that will serve the new ignition system.
Recycled Generator Device It is enough to do the following:
- make a modulator-breaker of the electrical circuit;
- install a breaker on the rotor shaft or generator.
You can create a modulator with your own hands. To do this, take a metal plate and drill a hole in it for the mounting bolt. The fabricated part will serve as a chopper modulator.
Homemade interrupt modulator The modulator is connected as follows:
- install the modulator plate (2) and tighten it with the bolt (3), but not completely;
- by rotating the crankshaft, you need to ensure that the piston is at top dead center;
- then you need to set the ignition timing;
- now you can tighten the mounting bolt on the plate.
Hall sensors (1) are installed together with the modulator.
Improving the stock system
The ignition system can be improved in other ways. To do this, you need to identify what are the problems with the wiring. They can occur in the primary circuit between the coil and the 12V battery or are caused by operating conditions. A visual inspection of the primary circuit can reveal problems in the connections, contacts and ignition switch.
If the operating conditions are ideal, the primary circuit will work with the 12V battery without failure.
But when dirt and dust get into the circuit, the resistance at the contacts increases, which leads to a decrease in voltage from 12 volts to 7-8 volts. This voltage is not enough for a powerful discharge to appear in the secondary winding of the coil. As a result, a charge of less than 12 V arises on the candle, which poorly ignites the combustible mixture in the cylinders. Burnt contacts, oily spark plugs and batteries with a charge of less than 12 V further impair sparking.
Standard wiring after modification The following measures help to solve these problems:
- The plug connectors are removed and each wire is soldered using traditional soldering and then insulated.
- An additional toggle switch is installed, which turns off all consumers when the engine starts. Thus, 12 volt voltage is supplied to the coils from the battery (diagram 1).
- Remake the ignition lock (ЗЗ) (scheme 2). You need to take the wire and solder one end to the lock connector 4, which is free, and the other to the positive terminal of the coil. The standard wire should be soldered from terminal 5 to terminal 6. After turning on this key position, the power supply from the battery to the primary circuit is carried out according to a simplified scheme.
Thus, the changes made will make the electrical wiring of the IZH Jupiter 5 motorcycle more reliable and productive.

Contactless electronic ignition on the legend of the domestic motor industry - IZH Jupiter 5
Motorcycles IZH are rightfully considered legends of the domestic automotive industry. The use of these vehicles was especially relevant in the Soviet years, however, even today ILs are successfully used by many domestic motorists. In this article, we will talk about what constitutes electronic ignition on an IZH Jupiter 5 motorcycle and how the ignition system (SZ) is configured.
Tuned motorcycle IZH Jupiter 5 IZH Jupiter 3 uses contactless ignition (BSZ) 1137.3734, designed for all models equipped with a 12-volt generator. The ignition coil module for Jupiter 4 or another model makes it possible to select the appropriate mode of operation of the motor due to the serial connection of the output wires.
The device as a whole improves the technical parameters of the vehicle due to:
- improved engine start at low temperatures;
- more stable operation of the power unit, which is achieved by reducing the asynchrony of spark formation, as well as by optimizing the lead angle of the SZ in accordance with the engine speed;
- lowering the level of toxicity of exhaust gases, fuel consumption, as well as reducing plaque on candles;
- stable start of the power unit even on a battery that has run down to 6 volts, provided that certain models of ignition coils are used;
- easier installation and maintenance of the system as a whole.
Technical data
Operation of contactless SZ on Jupiter Let us briefly consider the main technical parameters characteristic of the third IL model:
- The negative terminal of the battery is always grounded, the battery voltage level is 12 volts.
- If the ignition switch is turned off, respectively, the motor is not working, the current consumption parameter will be no more than 0.15 amperes.
- The knot allows you to ensure the uninterrupted appearance of a spark if the number of revolutions of the crankshaft does not exceed 7 thousand per minute. The level of current that the node consumes in this case will be no more than 2.5 amperes.
- In addition, the mechanism also makes it possible to ensure the uninterrupted formation of a spark if the voltage parameter in the electrical circuit changes from 6 to 16 volts. During this time, the voltage indicator on the candles will not change.
- According to the technical data, the unit can function normally if the air temperature is from 25 degrees below zero to 60 degrees Celsius.
- Thanks to the use of a microprocessor component in the operation of the unit, the formation of the moment allows you to ensure the correct and stable operation of all other mechanisms. Of course, if the power unit is operating in normal mode.
Scheme
IZH motorcycle ignition circuit As for the circuit, the optical ignition on IZH Jupiter 5 or any other SZ is mounted using the spare parts and fasteners that are included in the kit. As you know, the mechanism is designed to ignite the air-fuel mixture. The mixture itself, which is located in the engine cylinder, ignites due to a spark formed between the electrodes of the candle. It's no secret that the quality of the functioning of the SZ largely affects the operation of the entire vehicle.
As practice shows, one of the problems of IZH is that the lead angle periodically goes astray. This is due to the wear of the cams, as well as the contacts of the interrupting device. It should be noted that mechanical effects in the electronic SZ are completely absent.
The pulse is removed in a separate unit, while the signal is fed to the switch, where it is amplified. Subsequently, the impulse enters the coil, then everything happens as usual. A discharge enters the candle, which contributes to the ignition of the mixture, as a result of which the crankshaft begins to move. It is not so difficult to replace the device or adjust it at home, but you need to remember that incorrect actions can lead to possible malfunctions in the future.
To tune the system on a motorcycle, it is advisable to use devices with a scale of up to 15 volts and an internal resistance of up to 0 kOhm. Thanks to the electronic device, adjusting the assembly does not take much time and effort. The terminals from the device must be connected to the Hall sensor. In more detail, the procedure for setting up contact ignition without the use of auxiliary devices is shown in the video below (the author of the video is Khan Rulyu's channel).
So, for the correct setting, place the cylinder piston in a position that provides the most optimal spark formation. Any cylinder can be used. Then the ignition is activated, while the modulator device must be turned in the direction of the rotor movement by the crankshaft. Turning is carried out until changes are visible on the voltmeter screen. At the moment when you can catch a spark, the position of the shutters should not be changed. As for the modulator device, it must be securely fixed to the generator shaft, for this a fixing screw is used.
During adjustment, in any case, close the high voltages on the motor housing. This is done so that when using a short circuit, the system is not overloaded, which ultimately can lead to failure of the BSZ. In addition, the operation of the motor must not be stopped when dismantling the candle caps.
After the adjustment is made, the performance of the system must be checked. If you place the cable to be tested about 7-8 mm from the power unit, and then try to start the engine, a spark should slip through. As you can see, in general, the node setup procedure is not particularly complicated, but it requires care and the right approach, so the above recommendations should still be taken into account. In addition, one should not forget about safety precautions, since incorrect actions can lead to a short circuit in the wiring and failure of the assembly as a whole.
Video "Instructions for setting the ignition on a motorcycle IZH Jupiter 5"
How to carry out this task correctly at home, you can learn from the video below, which describes this procedure in detail (author - Kirilldo911).
The IZH Planet 5 wiring diagram has a simple design: a single-wire DC network is provided by a 12-volt battery, which is charged by a 100–140-watt generator. The role of the negative wire in the electrical circuit is performed by the metal frame, and since the rest of the wiring has a positive charge, their short circuit is often the main cause of the malfunction.

Generator IZH Planet 5 
Generator device
Battery
To supply all components, a low-power energy storage device of exactly 12 volts is required, since there is no starter in IZH Planet 5. The task of the lead-acid battery is only to supply voltage to the ignition system and the excitation winding of the generator during start-up.
Battery
Ignition system
In IZH Planet 5, the ignition coil converts low-voltage voltage to high-voltage and transfers it to the spark plug. That, in turn, is responsible for the spark that detonates the fuel. In order for detonation to occur only in the desired position of the piston, there is an ignition interrupter.
Ignition system
In the factory, this model has a classic ignition system, which requires periodic cleaning of the breaker contacts and adjusting the gap between them.
Installing contactless coolant on a motorcycle gives:
- timely powerful sparking;
- reduction of vibration level;
- reduction in fuel consumption.
control devices
The motorcycle has the following controls:
- tachometer, on which there are control lights for head light and turns;
- speedometer showing total and daily mileage;
- power engine temperature gauge;
- voltmeter.
control devices
Headlight and instrument panel lamps

Maintenance
The owner himself can perform some maintenance procedures:
- check the motorcycle alternator if the battery loses charge;
- set the gap between the contacts of the breaker;
- adjust the sound quality.
The need for inspection and adjustment of the wiring operation arises if:
- the motorcycle moves in the rain for a long time, as this causes oxidation of the contacts;
- a motorcyclist rides in an area where there is a lot of vegetation that damages the wiring;
- the driver rides in winter on snow, which can stick to electrical wiring parts and damage them.
Self-test of the Planet 5 motorcycle generator in case of loss of charge
The reason for the loss of charge in the IZH Planet 5 battery is most often a breakdown of the generator.
To check with your own hands you need:
- multimeter instrument;
- straight screwdriver.
Step-by-step instruction
The following steps must be followed:
- Disconnect the wires from the battery and remove the generator cover.
- Disconnect the 5 upper wires from the generator by unscrewing their fasteners before that. In order not to confuse the wires during assembly, it is worth marking them.
- Measure the resistance of the windings using a multimeter in ohmmeter mode. To do this, you need to touch one probe to the body, and the other should be connected in turn to 3 winding wires. There should be no short circuits, as indicated by the inscription on the screen of the multimeter.
- Test the resistance between the stator contacts: you need to touch them in turn with the probes of the multimeter. The value on the screen should be 8 ohms.
The presence of a short circuit at the 3rd stage or a discrepancy between the indicators at the 4th stage will indicate problems with the generator.

Step #4: Resistance Testing
How to correctly set the gap between the contacts of the breaker?
In order to set the gap between the contacts of the breaker, you will need:
- straight screwdriver;
- wrench for 10;
- key for candles;
- probe 0.4 mm thick (+/- 0.05 mm).
- Mount the motorcycle on a stand, transfer the box to neutral.
- Remove the right crankcase cover and unscrew the spark plug.
- Using a 10 wrench, grab the alternator rotor mounting bolt and turn the crankshaft to a position where the contacts are as far apart as possible.
- Loosen the contact attachment screw.
- Place the probe between the contacts and adjust the tightening of the eccentric screw until the probe passes the contacts with little resistance.
- Tighten the contact attachment screw.
Possible malfunctions, ways to detect and eliminate them.
When the engine is not running and the ignition is on, the control lamp on the headlight burns with a weak glow. Check the degree of charge of the battery, connect to its terminals a brake light lamp from the rear light or a large headlight lamp. If the battery is in good condition, the lamp should glow normally. Check the reliability of the connection of the contacts of the electrical wires in the battery - central switch circuit.
The control lamp burns at all engine speeds with an even glow. First of all, check the operation of the generator, for which the “Sh” terminal of the generator is connected to “ground” and the lamp is connected to the “I” and “Sh” terminals. If, when the engine is running, the lamp does not light or burns with a weak glow, then the generator is faulty, and in this case it is necessary to check:
1. Ease of moving the brushes in the brush holder. In case of jamming, clean the brush holder.
2. The presence of contact between the brush and the current-carrying wire - external examination. Replace brush if necessary.
3. The presence of contact between the brushes and the commutator, the absence of the brush hanging in the brush holder on the wire - external inspection, if there is no contact due to heavy wear, replace the brush.
4. The condition of the collector surface - external inspection, in case of contamination or oiling of the surface of the lamellae, rinse the collector with gasoline or clean it with glass sandpaper.
5. Check the serviceability of the excitation coils of the generator stator. Disconnect the wires coming from the bundle from the terminals "M", "I", "Sh" of the generator without removing the output wires of the excitation coils from the terminals "I" and "Sh". Disconnect the output wire of the excitation coils (additional resistance) from the ground. Then connect one terminal of the battery to the terminal of the generator "I" or "Sh". Connect any motorcycle lamp in series to the second terminal of the battery, and the second contact of the lamp to the free terminal "I" or "W".
If the lamp does not light up, then there is an open in the excitation coils (usually due to the lack of contacts at the junctions of the excitation coils). It is necessary to check the joints of the coils, and if necessary - solder.
If there is no open circuit in the excitation windings, i.e., the lamp is on, then it is necessary to additionally check that the excitation windings are not shorted to ground. To do this, connect one terminal of the battery to the "mass" of the generator, and the second - through the lamp to the terminal "I" or "Sh". If the lamp does not light, then there are no short circuits and the generator stator is working. If the lamp is on, then you should find the place of the circuit. To do this, remove the stator from the engine and re-check the absence of a short to ground in the stator coils as indicated above. If the short circuit is eliminated after removing the stator, then it was caused by the contact of the screws securing the generator to the excitation coil due to insulation failure or by the contact of the screws with the wires of the excitation coils at the joints. Troubleshoot. If the lamp is on when the stator is removed, then the excitation coil is closed by contact with the pole. To determine the location of damage, alternately disconnecting the excitation coils from each other, check each for the absence of a short circuit with the "ground" in the above way. Put the damaged coil back to rest by unscrewing the screws securing the pole, and put insulation on the damage site, securely fasten the coil with the pole to the stator.
It should be borne in mind that if the screws for fastening the pole are not tightened enough, it may touch the anchor. If the stator is good, but the generator is not working, then the armature is faulty. The anchor needs to be replaced.
The generator is working, but the control lamp burns with an even glow at all engine speeds. Check the operation of the relay-regulator. First, with the engine running, check whether the contacts of the reverse current relay are closing. If there is a contact closure, i.e., the armature is pulled up, then it is necessary to turn off the engine, turn off the ignition and, with the battery disconnected, clean the contacts of the reverse current relay with a safety razor blade. It is unacceptable to clean the silver contacts of the relay with emery or glass sandpaper, since in this case the abrasive cuts into the metal and breaks the electrical contact.
If the relay contacts do not close, and the armature is attracted , then you should check the adjustment of the gaps and the moment of operation (section "Relay-regulator"). In the event that the armature is not pulled up and the contacts do not close, check the adjustment of the regulator, since the reverse current relay may not work at low voltage.
The control lamp goes out only at high engine speeds. The reason is the low voltage maintained by the relay-regulator. Check and adjust voltage regulator.
When the engine speed increases and the light is on, the lamps burn with overheating or burn out - due to the high voltage maintained by the relay-regulator. Check and adjust voltage regulator.
The control lamp at increase in turns of the engine burns with overheating . The battery is connected incorrectly (reverse polarity of the battery terminals) or the alternator is reversed.
Check and, if necessary, correctly connect the battery to the electrical circuit. If the battery is connected to the electrical circuit correctly, then the generator is reversed. To reverse the polarity of the generator, it is necessary to open the relay-regulator and, with the ignition on, but the engine not running, briefly close the contact of the reverse current relay.
When the ignition is turned on without pressing the button, a signal sounds. The signal wire is shorted to ground. Remove the light switch from the steering wheel and, if the signal continues to sound, find the short circuit of the signal wire. If the sound of the signal stops when the light switch is removed from the steering wheel, then a short to ground occurs in the switch.
When you press the foot brake pedal, the rear brake light does not come on. Check lamp. If it is working, check the correct installation or adjustment of the brake light switch.
At one of the positions of the central switch and the light switch, the lamp corresponding to this position does not light.The reason is a lamp burnout or a broken contact at the junction of the wires. Check the lamp with the battery, replace if necessary. If the lamp is in good condition, using the electrical circuits, check the presence of contacts in the lamp sockets and the reliability of the wires at the junctions.
The IZH Jupiter 5 motorcycle has been produced from 1985 to the present at OAO Izhevsk Motorcycles. The basis of such popularity of the model is the design, good technical characteristics and a successful wiring diagram of IZH Jupiter 5, which, unlike the previous generation, allows the use of a large number of various electrical equipment.
The fifth model of Jupiter belongs to the middle class of road motorcycles, can travel on roads with different surfaces and, which is very important, be equipped with a cargo or passenger trailer with a load capacity of up to 100 kg, slightly inferior in loading with a sidecar. Other positive properties of IL Jupiter 5 include:
- Powerful engine.
- Maintainability (do-it-yourself repairs are possible even in rural conditions).
- Economy in operation.
- Affordable cost.
- High-quality electrical circuit with a powerful generator.
Among the technical parameters of the motorcycle, the main ones should be highlighted:
- power - 25.0 liters. With.;
- engine capacity - 348 cubic meters. cm;
- type of lubrication - joint;
- top speed- 125 (95 with a trailer) km / h;
- fuel - gasoline A76;
- cooling - air;
- frame design– welded tubular;
- electrical equipment voltage- 12 volts (battery sources, generator).
Ignition on IZH Jupiter 5 is made in a contact version through a switch with a connection to the battery.
Electrical equipment IZH Jupiter 5
An important element of the motorcycle device is a large number of electrical equipment. The electrical circuit of the IZH includes the following elements:
- battery; - 12 volts
- alternator: - 12 volts
- switch;
- headlight;
- dashboard;
- wiring;
- sound signal;
- turn relay, direction indicators;
- stop signal;
- charging relay;
- combined switch;
- ignition coil, spark plug;
- relay regulator;
- rectifier, fuses.
With such a large amount of electrical equipment in the wiring on IZH Jupiter 5, many special terminals were used to fix the connections, which made it possible, in case of problems, to quickly disconnect the faulty element for repair or replacement.
To properly disconnect faulty parts, the owners most often used the IZH Jupiter 5 color wiring diagram with a detailed description, which, if necessary, could also determine how to connect certain elements of the circuit.
Major motorcycle wiring problem
On IZH Jupiter 5, the wiring had a large number of contact terminals. Therefore, the main cause of malfunctions in the electrical circuit was a violation of the integrity of the connections. This led to such moments as, no charging for the battery, the generator does not provide the necessary 12-volt voltage to the system, the switch is not able to generate the necessary charge for the ignition coil, loss of performance of all lighting devices, and a number of others.
The reason for the loss of connection in the terminals was the contamination and oxidation of the contacts. This was especially true for motorcycles produced at the beginning of mass production. The main way to solve this problem was to exclude these terminals from the wiring of IZH Jupiter 5.
To do this, soldering the wires directly to each other was used (similar to), as well as sealing the terminals on the lead wires to the following main elements:
- battery;
- generator;
- coil and spark plug;
- switch;
- lighting devices.
This increased the reliability of the connections and, as a result, ensured the operability of these parts, and also made it possible to turn on the charging for the battery in order to subsequently confidently start the engine of the IZH Jupiter 5 motorcycle.
