Download electric circuit of the motorcycle Izh Jupiter 5. Electrical circuit of the motorcycle Izh planet sport

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:

1. Powerful engine.
2. Maintainability (do-it-yourself repairs are possible even in rural conditions).
3. Economy in operation.
4. Affordable cost.
5. 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.

Wiring on Izh Jupiter 4 is an extremely simple and reliable element of a motorcycle that is only afraid of breaks in the circuit, and does not pay any attention to other features of operation and even the passage of time. But there are also disadvantages, first of all, the archaic nature of the system, which includes contact ignition, a weak generator, inefficient head light and the absence of such useful “features” as charging a smartphone. In this regard, we decided to tell you what the Izh Jupiter 4 wiring diagram looks like and how to independently connect the entire electronic circuit of a motorcycle from scratch.

Let's start with the general scheme, because all improvements, as well as the restoration or repair of individual parts of the wiring, begin precisely with the study of the connection system.

The image on the right says:

• 1 - power off (emergency);
• 2 - day and night lighting mode;
• 3 - rear brake stop indication relay;
• 4 - start on a low charge;
• 5 - right turn;
• 6 — a lamp of illumination of a speedometer;

This scheme of the Izh Jupiter 4 ignition system is all that is needed to answer the question "How to wire on Izh Jupiter 4?". Based on it, you can understand the intricacies of wires and their colors (for standard wiring). This circuit will serve as a template for us for the alterations that invariably form part of the old electrical circuit.

We modernize the electrical equipment of the motorcycle with our own hands

We have already paid attention to the weaknesses of electrical equipment, so let's look at the main points that should be replaced in a motorcycle for more convenient everyday use.

Ignition system

From the factory, the motorcycle is equipped with a simple contact ignition system. The system is quite reliable and can run thousands and even hundreds of thousands of miles without interruption. She also has significant drawbacks, such as the inability to maintain the lead angle settings for a long time. This is due to the fact that the fixation of the desired position occurs with the help of bolts, which are weakened by vibration and the setting “leaves”.

Therefore, we propose not to torment yourself and equipment with constant repairs, but to install a more modern - Contactless Ignition System or BSZ. In online stores, you can easily find a suitable set, which remains to be installed and connected according to the diagram.

Energy efficient lamps

Old incandescent lamps, like ignition, have already outlived their usefulness, so they should be replaced with more productive and economical ones. Each lamp has its own purpose, so when replacing it, you should take this into account. For example, direction indicators and a taillight - signal our presence or maneuvers, the light from them should be bright, but visible only to other road users. Therefore, they should be replaced with LEDs that have sufficient brightness and the lowest power consumption.

High-quality LEDs for headlights will be expensive, so we will limit ourselves to new halogen incandescent lamps. Here, we don't give a damn about energy consumption, because the first place comes out - safety when moving at dusk and at night.

Generator

Frankly, the weak link of the entire electrical system is the generator. Its power is sometimes not enough even to maintain regular consumers, which is why when driving at night, over time, the battery may run down and the lighting intensity will noticeably drop, since part of the generated current will go to charge the battery. To prevent this from happening, it is best to install a new generator. It, with minimal alterations, can be rearranged from 4-stroke Chinese mopeds or you can purchase a new, factory-made generator suitable for Jupiter 4.

This conversion makes sense if you're going to go further and put additional consumers on the bike, otherwise it's better to leave this money for other improvements or for a fresh batch of consumables.

Additional devices

Finally, we came to the question of how improved wiring is done on Izh Jupiter 4 with our own hands. It should be noted right away that in stores specializing in Soviet technology you can already find various kits ready for installation, among them:

• charging stations for smartphones;
• "musical" sets, consisting of a compact player and a set of special speakers;
• tachometers (can be installed after replacing the ignition with a non-contact one);
• digital instruments;
• helium batteries and many other useful elements.

The above wiring diagram for Izh Jupiter 4 will help you figure out how to connect one or another item from the list, plus each product already comes with a wiring diagram.

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.

Features of electrical equipment

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.

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.

On the electrical circuit of the IZH motorcycle, the components are marked with numbers:

1. Spark plug.
2. Ignition coils from Planet 5.
3. Switches.
4. Hall sensors.
5. Egnition lock.
6. 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:

1. The plug connectors are removed and each wire is soldered using traditional soldering and then insulated.
2. 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).
3. 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.

"Planet-sport" is the first Izhevsk motorcycle with 12-volt electrical equipment that meets all modern (as of 1982) requirements for this system.

Scheme of the electrical equipment of the motorcycle IZH Planet Sport I - parking light lamp; 2 - main light lamp; 3 - neutral control lamp; 4 - resistor; 5 - oil pressure control lamp; 6 — the relay of indexes of turn; 7 - block of diodes (decoupling); 8 — a lamp of illumination of a scale of a speedometer; 9 - ignition switch; 10 — forward lanterns of indexes of turn; II - headlight switch and emergency ignition switch; 12 — the switch of a stoplight of a manual brake; 13 - relay-regulator; 14 - neutral lamp switch; 15 - high beam control lamp; 16 — a lamp of control of indexes of turn; 17 - lamp for monitoring the operation of the generator; 18 - sound signal; 19 - light switch and direction indicators, horn switch; 20 - spark plug; 21 - ignition coil; 22 - foot brake switch; 23 - generator; 24 - battery; 25 - fuse; 26 - rectifier; 27 - oil pressure sensor; 28 - taillights of direction indicators; 29 - rear light.

Improving the car, the plant made a number of changes to it. In particular, the fixation and clarity of operation of the switches IZH P101 and IZH P102 and the switch on the steering wheel have been improved. The optical element of the Hella company in the headlight was replaced by the Soviet FG 137, and the IZH UP1 lamps of the direction indicators were replaced by unified lamps 16.3726. There are other innovations as well.

Jupiter-4 is now also equipped with 12-volt equipment. The plant is also preparing for production a new Planet-sport model, the electrical equipment of which is unified with Jupiter-4.

However, already now the owners of Planet-Sport can use a number of IZH Yu-4 electrical appliances without significant alterations. These include generator 28.3701 (if it is sold without a breaker and a capacitor, they can be taken from the old IL GP1); direction indicator lights 16.3726; optical element of headlight FG 137; rear lamp FP146; speedometer SP102; rechargeable battery 6MTS-9.

To install the turn signal interrupter IZH RP2SM-10 into the headlight housing, it is necessary to make an additional bracket from a steel strip 1-1.5 mm thick and replace the plug-in tips with round ones. After the same alteration of the tips, the combined switches IZH P101-20 and IZH P102-20 from the IZH Yu-4 motorcycle can also be used on Planet-Sport. To do this, pressing the fixing antennae with an awl or a knitting needle, remove the plug tips. They are cut off and round tips are crimped and soldered on the stripped ends of the wires. At the IZH P101-20 switch, a blue outlet wire 130-150 mm long with a plug tip is also soldered to the black wire.

The improvement of the electrical equipment of motorcycles and the use of new devices have naturally led to some complication of the electrical circuit. Let's get acquainted with its main elements using the example of the electrical equipment of the Planet-Sport scheme, which is in many ways similar to the schemes of other Izhevsk motorcycles.

Ignition system. This is perhaps the main system, because without it the motor cannot work. Let's trace and remember its electrical circuit. From the battery 24, through the fuse 25 and the rectifier 26, power is supplied to the terminal (2) of the connecting panel in the headlight housing and then to the terminal (3) of the ignition switch 9. When the key is turned to position I, the terminals (3-2 - 1 and 5 -6). Now, from the terminal (1) of the lock, the current goes to the terminal (5) of the connecting panel, from it to the emergency ignition switch 11, and through its closed contacts to the terminal (1) of the connecting panel and then to the primary winding of the ignition coil 21 (the second end of the primary winding - the "-" terminal is connected to the breaker). Thus, the circuit of the motorcycle ignition system is turned on.

If the engine does not run due to the absence of a spark at the plug, check if high voltage is being supplied to it. To do this, remove the wire from the cap and bring it to the edge of the cylinder with a gap of 2-3 mm. If no spark appears between the wire and the cylinder when the crankshaft is rotated by the kick starter, there is no high voltage. The reason for this is found as follows. When the ignition is turned on, a 12-volt test light is used to check whether power is supplied to the “+” terminal of the ignition coil. If not, then check the entire circuit, starting from the battery. A common cause of no voltage is loose or oxidized terminals, or a faulty fuse.

Having achieved that a normal voltage appears on the “+” terminal of the ignition coil, carefully clean the breaker contacts, check and set a gap of 0.4-0.6 mm between them and adjust the initial ignition timing.

If the engine gives only separate flashes at start-up, and a white coating appears on the breaker contacts, it means that the capacitor has failed (rarely, but this happens).

With the correct gap, clean breaker contacts and a working capacitor, the reason for the absence of a spark on the candle may be a malfunction of its plastic cap (breakdown to ground) or the ignition coil (it is non-separable, so it is replaced). A bad spark plug can cause the engine to misfire or make it difficult to start. Alarm and lighting system

direction indicator. When the ignition is turned on (the key is in position I), electricity from the battery 24 (or rectifier 26 when the engine is running) is supplied through the terminals (3 and 1) of the ignition switch 9 to the terminal (5) of the connecting panel. The power wire of the relay 6 of the direction indicators, the sound signal 18 and the "positive" wire of the light switch 11 located on the steering wheel are connected to it. From relay 6, power is supplied to the lights through the terminal (9) of the connecting panel and then to the switch 19 of the direction indicators. From it, through the terminals (6 and 7) of the connecting panel, it goes to the lights 10 and 28 of the direction indicators. The control lamp 16 of the direction indicators is also connected to the terminals (6 and 7) of the connecting panel through the block of diodes 7.

The reason for the failure of the direction indicators most often is the lack of "mass" in the lamps when their fastening to the frame is loosened, oxidation or loosening of the connections of the tips with wires, contacts in the lamp sockets.

To speed up troubleshooting, the circuit is checked from the idle consumer to the power source. To determine the operability of the relay 6 of the direction indicators without dismantling it, you must first make sure that the terminal (5) of the connecting panel is energized, and the brown wire of the relay is securely connected to ground. Then check the continuity of the circuits going to the direction indicator lamps by connecting terminal (5) with terminals (6 and 7) of the connecting panel with a separate wire. The lights of the right (terminal 6) or port side (terminal 7) and the control lamp 16, if the circuits are in good condition, should burn without blinking. Then disconnect the pink relay wire from terminal (9) and connect it to terminals (6 and 7) of the connection board. With a working relay, the lights of the starboard or port side should flash at a frequency of 60 to 120 per minute.

The relay removed from the motorcycle is checked using two A12-21-3 control lamps (power of each 25 W) connected in parallel. Connect the “plus” of a constant voltage of 12 volts to the red wire, “minus” to the brown one, and control lamps to the pink one. With a working device, the lamps should flash at a frequency of 90 ± 30 per minute.

Farah. It contains the main part of the wiring diagram, the turn signal relay, the neutral 3 and oil pressure warning lamps 5, the lamp 8 illuminating the speedometer scale, the parking light lamp 1, the head light lamp 2, the ignition lock 9 and the speedometer.

On the latest models of motorcycles, the turn signal breaker is mounted on the frame under the gas tank.

Consider the electrical circuit of the head, parking and clearance light. With the ignition on (key in position I), power is supplied to the terminal (4) of the connecting panel, then through the contacts of the light switch 11 to the central contact of the high-dipped beam switch 19. Then through the terminals (11 and 12) of the connecting panel - to the thread of the high or low beam of lamp 2.

The position light in the headlight (bulb 1) and in the rear lamp 29 lights up when the switch 11 is activated and current flows through the contacts (5 and 6) of the ignition lock 9.

If the ignition key is turned to position II (parking), then these lamps are powered through its contacts (3 and 5) regardless of the position of the switches on the steering wheel.

Lamps that dimly glow when the engine is not running indicate that the battery is not fully charged. If this is observed in all engine operating modes, it means that the voltage in the lamp supply circuit drops sharply. In this case, check the electrical connections of the power and ground wires, clean and tighten the screw and plug connectors, the contacts in the lamp sockets of the headlights and lanterns. Check the serviceability and reliability of the contacts in the switches and fuse.

Since the motorcycle is constantly being improved during the production process and its electrical circuit changes, it is advisable to mark the differences of your motorcycle in the circuit printed here so that, using it, you can always easily and quickly find the right circuit and determine the malfunction.

Reverse current relay. In the electrical system of a motorcycle, the battery and alternator are connected in parallel. With an increase in the number of revolutions of the crankshaft of the engine, the number of revolutions of the generator armature increases, and hence its voltage. Therefore, if there is no regulating device in the generator-battery circuit, then the battery will be systematically recharged when the generator voltage increases, which will lead to its failure. If the generator voltage is lower than the battery voltage, then the latter will be discharged through the generator, which may also become unusable.

The functions of such a control device are performed by a reverse current relay (ROT). To ensure the normal operation of consumers installed on the motorcycle, as well as a rational mode of charging the battery within the specified limits, a special voltage regulator (PH) device is included in one unit with a reverse current relay.

The reverse current relay consists of an electromagnet core 4, an armature 3 with a spring 12, two contacts 1, 2 and a yoke 13. Two windings are wound on the core: a thin shunt (SHO) and a thick serial (CO). In the free state and at idle (low) engine speed, the contacts are in the open state and all consumers are powered by batteries. With an increase in the number of revolutions of the generator armature, the voltage in the network increases. Accordingly, the current passing through the thin winding (SW) increases, the core attraction force overcomes the spring force, the armature is attracted to the core, the contacts close, and the electric current from the generator goes to charge the battery and to other consumers. As soon as the generator voltage drops below the battery voltage, the relay contacts will open under the action of the spring.

Voltage regulator consists of an electromagnet core 7, an armature 6, fixed and moving contacts 5, a return spring 8 and resistances 9, 10. Three windings are wound on the core of the voltage regulator: shunt - SHO, compensation - KO and serial - CO. When the generator armature does not rotate or rotates at a low number of revolutions, the two-way movable contact of the voltage regulator is pressed against the upper fixed contact connected to ground by the force of the armature spring. In this case, the excitation winding 11 of the generator is connected to ground through the compensation winding KO and contacts 5 of the regulator.

With an increase in the number of revolutions of the generator armature, the electric current passing through the serial winding magnetizes the core of the electromagnet and attracts the armature 6 of the regulator and its two-sided contact 5 moves to the middle position, that is, it opens. In this case, resistances 10 and 9 connected in series at 4.4 and 1.2 ohms are included in the circuit of the excitation winding of the generator and the compensation winding. With a further increase in the number of revolutions of the armature, the additional resistance is not enough to prevent an increase in the generator voltage in excess of the specified limit. Armature 6 is strongly attracted to the electromagnet and double-sided contact 5 is pressed against the lower fixed contact, short-circuiting the excitation winding of the generator. The generator voltage decreases, the voltage regulator armature returns to the middle position or closes with the upper fixed contact. Vibrating, armature 6 with double-sided contact maintains the generator voltage in the range of 6.5-7 V.

When the generator is overloaded, the serial winding of the regulator, additionally magnetizing the electromagnet, limits the maximum generator current.

Possible malfunctions of the voltage regulator and care for it. The voltage regulator is adjusted at the factory and this setting should not be violated unnecessarily. Care comes down to monitoring the condition of the wires attached to the relay terminals and keeping it clean.

A malfunction of the voltage regulator disrupts the operation of the entire electrical system. The main signs of a malfunction are: bright burning of lamps or their burnout. The electrolyte boils away and the battery drains quickly, especially when the motorcycle is used at night. During operation of the motorcycle, control over the operation of the regulator is carried out by the red control lamp located in the headlight.

Turning on the control lamp at speed (1100 - 1200 rpm) indicates a malfunction of the regulator or generator.

Operating the motorcycle with the warning light on will drain the battery. The relay-regulator is a very sensitive device and you can entrust its adjustment to a highly qualified specialist.

Checking and adjusting the voltage regulator is carried out at idle speed of the generator, that is, without any loads. Therefore, between contacts 1 and 2 of the reverse current relay, it is necessary to lay an insulating gasket made of paper. In this case, the ignition coil will be powered by the battery. Connect a voltmeter to terminals "I" and "M". Start the engine. At medium engine speeds, the voltage should be in the range of 7.3-7.8 V. If the voltage goes beyond these limits, then first you should clean the contacts 5 with a steel plate (razor blade), 0.05-0.1 mm thick, but in no case with an emery cloth. Cleaning should only be done with the engine off. If the stripping did not give positive results, you should check the gap between the armature and the core of the electromagnet 7 (0.9-1.1 mm), as well as between contacts 5.

The gap between the contacts 5 is checked as follows: between the armature 6 and the core of the electromagnet 7, insert a probe 1 mm thick and press the armature to the core. At this moment, the gap between contacts 5 should be 0.25-0.30 mm (checked with a second probe). If the gap is not maintained, it is necessary to bend the holder of the upper contact. Check clearances and tension again. If necessary, the voltage can be adjusted by changing the tension of the armature spring 8 by bending the lower spring holder. With increasing spring tension, the voltage in the circuit will increase, with weakening, it will decrease. It is necessary to bend the spring holder when the engine is not running, and when checking the voltage with a voltmeter, the engine must run at high speeds.

After completing the adjustment of the voltage regulator, remove the insulating gasket from the gap between the contacts of the reverse current relay.

Checking and adjusting the reverse current relay. To check and adjust the reverse current relay (ROT), you need an ammeter with the zero position of the arrow in the middle of the scale (scale 5-0-5A). The voltmeter is connected in the same way as when adjusting the voltage regulator, and the ammeter is connected in series to the battery.

Before proceeding with the adjustment, it is necessary to check the compliance of the gaps, the value of which should be: between contacts 1 and 2-0.25-0.35 mm and between armature 3 and the core of the electromagnet - 0.6-0.8 mm. If it is necessary to adjust the gap between the armature and the core, the contact holder must be moved with the screws loosened.

The gap between the relay contacts is adjusted by bending the contact post. To check the voltage, you need to start the engine and, gradually, adding speed, notice the voltage at which contacts 1 and 2 close. At the moment of closing the contacts, the needle of the voltmeter shudders slightly. The contacts should close at a voltage of 6.0-6.4 V. The reverse switching current of the relay with correctly set gaps and switching voltage should be within 0.5-4 A. If the contacts close at a higher voltage, then the lower spring holder 12 must be bent upwards, weakening the spring force. If it is less, then bend the spring holder down. Adjustment is made at low speeds.
