The electrical circuit of the vaz. Scheme of electrical equipment Key features of the functioning of the electrical equipment of the car

The wiring of the VAZ 2106 is arranged according to the principle of single-wire, which means a situation where all current consumers are powered by the mass of the car. In this case, it acts as the second wire (minus). Accordingly, all electrical components are made and connected for a specific work model.

Features of the electrical wiring of the "classic" models

The main characteristics that the VAZ 2106 wiring diagram has are the following:

• activation of electrical circuits directly through the ignition switch;
• connection to the battery with the participation of the fuse box;
• conductive cases of key units.

Thus, in the event of a failure of any system, it is advisable to search for malfunctions directly from the ignition switch and the contact group.

The role of this node is as follows:

• controls the vehicle ignition system;
• plays anti-theft, including security functions;
• allows towing a faulty car with the "emergency gang" turned on.

Reasons for repairing the ignition lock

The "six" ignition lock has 4 modes with different functionality:

1. Mode "0" allows you to feed only wires 30 and 30/1. The rest of the features are disabled.
2. Mode "І" makes it possible to work running lights, wiper drive, stove engine.
3. Mode "II" - in this case, the wiring on the VAZ 2106 activates the turn signals, the dashboard and the ignition system.
4. Position "III" of the key provides power to terminals 30/1 and 30-INT. The car starter is working.

Replacing the ignition switch with your own hands may be required for several reasons:

• Firstly, this is real in case of loss of keys.
• Secondly, over time, the ignition lock cylinder is subject to wear, and this affects the starting of the engine.
• In addition, there may be problems with the contact wire group, which can lead to.

Tip: By the way, this work is easy to do yourself, although the price for the services of an auto electrician will also not be unbearable. In order to perform these types of work, prepare in advance an awl and a Phillips screwdriver (well, and a new ignition switch, if necessary).

And it consists of the following elements and details:

• lock case;
• contact disk;
• locking rod;
• roller and contact sleeve;
• block.

Checking the operation of the distributor

How to change the lock

Dismantling the old node

Instructions for self-replacing the ignition switch will look something like this:

• disconnect the battery;
• unscrew the fixing screws of the plastic casing under the steering column and remove it;
• turn off the anti-theft device, for which you need to insert the key to position "0";
• the wiring of the VAZ 2106 requires the removal of the lock - for this purpose we insert the awl into the hole and snap off the latch;
• after you have removed the lock (see video), it is strongly recommended to mark the contact wires so as not to confuse them when reconnecting;
• Install the new lock in reverse order.

Replacing the contact group

The wiring diagram of the VAZ 2106 is designed in such a way that, if it is necessary to replace the contact group, this can be done without dismantling the ignition switch. However, if you can remove it within your strength, then putting it back almost certainly will not work. For this reason, we will need to perform all of the above operations.

Important! After removing the lock, pull off the retaining ring from its reverse side and install a new contact group (as in the photo).

It is recommended to purchase only high-quality spare parts, and it is better to do this from trusted car dealers, since today there are many fakes on sale. Distinctive properties of the original ignition lock will be the following characteristics:

• the case is molded carefully and with smooth edges;
• the top of the castle is rolled evenly;
• a wide hologram cannot be torn off without destroying it;
• free movement of the key in the larva, without interference.

What is contactless ignition and its advantages

Another interesting option for tuning classic models is the installation of a contactless type of ignition. Definitely, the car only benefits from such an innovation - the engine runs smoother, failures disappear when accelerating the car, it is much easier to start the engine in the cold season. In addition, there are savings associated with fuel consumption.

The wiring diagram on the VAZ 2106 in this case is almost identical: the main differences are the presence of a pulse sensor and the absence of a distributor. While the engine is running, the sensor creates pulses that enter the transistor switch.

Already with its help, other impulses are generated that are characteristic of the primary winding on the coil. With interruption, the secondary winding produces a high voltage current. From the distributor contact, current is supplied to the spark plugs in the required sequence.

So, you are purchasing a complete set of contactless ignition for the VAZ "classic", which must correspond in its characteristics to the car engine. Next, we need a wiring diagram for the VAZ 2106.

The following spare parts should be included in the configuration of such an ignition:

• switching unit;
• coil;
• high voltage wiring kit;
• spark plugs - DVRM;
• connecting wires.

Stages of work

To successfully replace the ignition with a contactless one, it is important to adhere to the principles of observing the correct work technology. Remove the negative terminal from your battery. Any kind of electrical repair should always begin with this action.

Here the wiring to the VAZ 2106 will come to the rescue:

1. We disconnect the wires and the main high-voltage wire from the ignition coil.
2. Remove the cover from the distributor.

1. The slider should be set so as not to knock down its necessary settings.
2. The mark on the block is placed where there are slots at the bottom of the distributor housing.
3. Unscrew the nut and take out the old distributor of the old, contact ignition system.
4. Before installing a new system, open the cover of the updated distributor and set the slider to the same position as on the old distributor. You can put it in the hole in the head of the block.
5. Move the mark to the required level and tighten the nuts.

Now you can assemble, as the VAZ 21063 wiring diagram suggests - the cover is put on, high-voltage wires are connected. You can start dismantling the old ignition coil (this was discussed above).

1. We install a new coil and bring another outlet of the high-voltage wire to it.
2. Now we put all high-voltage wires in their places. We need contact "K" for the brown wires of the new coil, while blue wires will go to pin "B".
3. You need to choose a place to place the switch, more often this is done in the washer reservoir area. It is fixed with self-tapping screws.

The VAZ 2106 wiring has been replaced, you can tighten the wires with electrical tape. It remains to start the engine and correct the operation of the ignition system.

Note! If the engine of your "six" began to work intermittently and intermittently, and this is also accompanied by a loss of power, then misfiring can easily be the cause.

The first thing to pay attention to in this case is the integrity of the wiring, including high-voltage, as well as the health of other elements of the ignition system. Spark plugs are checked on a separate stand. In some cases, the cause may be a faulty VAZ 2106 generator and wiring to it.

In conclusion

As you can see, there is nothing complicated in caring for a car electrician. It is only important to do all the work competently and accurately. Thus, you will extend the life of your iron friend. Good luck on the roads!

The electrical equipment on the VAZ 2106 car is made according to a single-wire circuit - the negative terminals of the sources and consumers of electricity are connected to the “ground”, which acts as a second wire. In the 90s, minor changes were made to the electrical circuit. So, now one sound signal is installed on the car without a relay for turning it on, the lights for signaling the open front doors and the relay-breaker for the hand brake warning lamp are not used. A rear fog lamp is also installed on the car. Some cars can be equipped with a heated rear window. Most circuits are turned on by the ignition switch. Always on (regardless of the position of the key in the ignition switch) are the power supply circuits for sound signals, cigarette lighter, brake light, ceiling lamps, portable lamp socket, alarm power supply circuit and front door open signal lights.

Introducing wiring diagrams for VAZ 2110 1996+ onwards For more active drivers, a 16-valve version with a 1.5-liter gasoline engine was developed based on this engine. with a capacity of 94 hp, with a twin-shaft cylinder head, providing increased performance in terms of power (69 kW) and torque (130 Nm), allowing the car to have improved dynamic qualities. A car equipped with such an engine has the VAZ 21103 index, the maximum speed is already 185 km / h, and acceleration to “hundreds” takes only 12.5 seconds. These modifications on the roads are becoming more and more common, as well as the 2-liter 150-horsepower versions of the VAZ-21106 CTi are quite economical, expressive and expensive. No wonder, because the Opel X20XEV engine with a twin-shaft 16-valve cylinder head and a point injection system allows you to accelerate to 205 km / h. With it, the hundred-kilometer barrier is overcome in just 9.5 seconds. There is also a combat 240-horsepower (!) VAZ-21107 "Rally" 2.0 V16 with a special roll cage built into the body. Its maximum speed is 220 km/h, and the acceleration time to 100 km/h takes only 7 seconds! But they make it piece by piece, only by order of athletes, and it costs like foreign rally cars: expensive (22 thousand dollars). I must say that some domestic tuning companies create (even without the use of expensive imported components) quite successful in speed or, on the contrary, comfortable versions of the "tens", dynamics, the handling of which is significantly improved when driving.

There are also all-wheel drive versions of the “tens” of a sports or all-terrain orientation, but they are either experimental or small-scale, and therefore expensive.

Scheme of the ignition system on the VAZ 2110

The quality of its work depends on the serviceability of the components and systems of the car. Modern cars are crammed with electronics, so the electrical system requires a lot of attention. The article analyzes the VAZ 2107, signs of a malfunction, and also discusses the features of carburetor engines and with an injector.

[ Hide ]

Symptoms

If the car refuses to drive, there are problems with electrical appliances or electrical wiring, this gives rise to troubleshooting by replacing faulty elements.

If the car does not start, the first thing to check is the fuel supply to the carburetor or fuel injector rail.

If fuel is supplied, then the problem of car failure to drive must be sought in the electrical system using the electrical circuit:

1. For a car with a carburetor, problems can be with the distributor, coil, candles, as well as with electrical wiring. After checking the elements of the electrical circuit for serviceability, it is necessary to replace the non-working components.
2. In a car with an injector, the problem may be due to an ECM (electronic engine control system) failure. Thanks to it, the signals coming from the sensors are processed and commands are transmitted for execution to the units (the author of the video is Alexander Skripchenko).

Possible problems due to burnt contacts in the ignition switch. For troubleshooting, you need 2107 indicating the elements that are consumers of the contact group.

carbureted engine

The operation of an engine with a carburetor has a classic scheme:

1. When the key in the ignition switch is turned to the "Starter" position, the electronic system supplies power to it.
2. The generator starts up.
3. The generator transmits electrical current to the coil. It is used to generate high voltage currents. The coil receives low voltage currents. Passing through the module, they are transformed into high-voltage ones and transmitted via to the distributor.
4. With the help of high-voltage currents, the distributor drive rotates the crankshaft of the power unit. He closes the contacts in order of priority and supplies an electric discharge to the candles.

The principle of operation is reflected in the electrical circuit of the engine with a carburetor.

Wiring diagram of the classics - carburetor

Classic ignition

The contact system includes the following elements:

• switch;
• coil;
• distributor;
• high voltage wires;
• candles.

Thanks to the distributor, the primary circuit of the ignition module is interrupted, and then the high-voltage current is distributed in the desired sequence to the candles. The coil converts low voltage current into high voltage current. Candles ignite the fuel mixture in the engine cylinders.

If the engine does not start when the ignition key is turned, the reason may be as follows:

1. Break in the electrical circuit between the generator and the coil. In this case, you need to check all the contacts and the integrity of the wiring.
2. Coil defective. It can be checked with a spark: remove the wire from the distributor and touch the metal part. If a spark appears during the operation of the power unit, then the module is working.
3. A break in the electrical circuit between the distributor and candles. In this case, you need a slider located there, a high-voltage wiring connecting the distributor cover to the candles.

After identifying and eliminating a malfunction in the carburetor, the engine should start without problems if the rest of the vehicle is in good condition.

Electronic ignition

On some VAZ 2107 models that were released after 1987, it was installed. Although the car was more expensive, it was in demand. The innovation was that an electronic switch was installed between the distributor and the coil.

Contactless ignition system includes:

• switch;
• ignition switch;
• coil;
• distributor sensor;
• high voltage wires;
• candles.

Using the distributor sensor, control signals are transmitted to the switch to form a spark and high-voltage current pulses are distributed over the candles. The function of the switch is to convert the control pulses from the contactless sensor into a pulsed current that enters the primary winding of the coil. Thus, it improves the formation of a spark if the engine is running on a lean fuel mixture.

The switch is checked with a spark. If during the check the distributor does not receive a high voltage pulse, then the switch is not working and needs to be replaced.

If, after replacing the switch with a new one, the problem remains, then it is necessary to replace the wiring on the VAZ 2107. Most likely, the reason lies in the high resistance of the wires, this entails a weak spark formation.

injection engine

The injection engine has the following differences from the carburetor:

• an electric pump that serves to increase the pressure in the fuel system (there is no pressure in an engine with a carburetor, and the pump is mechanical);
• the fuel mixture is formed in the cylinder itself, and in the classic version in the carburetor;
• electric injectors are responsible for fuel injection into the cylinders;
• the moment when the injection of the mixture is necessary is determined by the ECM (the mixture enters the carburetor when the intake valve is opened).

In an engine with an injection, a large number of electronic components. The reason for the failure of the motor may be a malfunction of the sensors and wiring.

You can find a malfunction in a car with an injector yourself:

• disconnect the sensor by removing the connector;
• check the resistance of the sensor using a tester;
• compare the results obtained with the nominal data, which can be taken from the table in the instructions attached to the car.

Having found a faulty sensor, it must be replaced.

Conclusion

Thus, it is clear from the article that knowing the principle of operation of an engine with a VAZ 2107 carburetor, in particular with a contact and non-contact ignition system, and an engine with an injector, it is possible to identify the cause of the vehicle's failure to start moving if the cause is electronics.

Knowing the cause of the failure and having experience in repair work related to electrical wiring, the driver will be able to fix his car on the road and return it to working condition.

Video "Disassembly of the electrical circuit of the car"

The VAZ 2109 car for many years remained one of the most popular in the country. Not just popular, but also prestigious. In the social hierarchy, the owners of nines were not much lower than the owners of used Cadets and Jetts. One could argue with the reliability of the car, but since there was no alternative, the car flooded the entire CIS and was even assembled by the nodal method in Finland, but this has little to do with the 2109 model.

Wiring diagram VAZ 2109

Like the whole car, the electrical equipment was not at the highest level, so the owners of the nines should know the wiring diagram of the VAZ 2109 thoroughly. To do this, we have given the factory scheme in good resolution, which can be used with amendments to the changes made from time to time.

This scheme is the canonical nine with factory markings and explanations. In principle, the circuit is quite simple, but the electrical appliances themselves caused difficulties, and we will talk about the problems with which we will talk.

Major Wiring Problems 2109

The biggest problem in the electrical equipment of the VAZ 2109 was the poor quality of components and unsatisfactory build quality. Despite the fact that Togliatti traditionally blames suppliers for all mortal sins, in the end we have to take the rap, and as ordinary users, we should not be at all interested in why the spirals on the double-filament taillight lamps constantly burn out. Also, in principle, we don’t care which factory made the cases for the fuse box - we only see inadequate operation of electrical equipment when the right turn is turned on when the brake pedal is pressed.

And there are many such examples. If the factory is not sure about the quality of the components, then why put them on the car. Therefore, rhetorical questions only lead to excessive fluctuations in the air, but do not solve the problem. The above problem with stops is solved quite simply:

Short circuits of the tracks of this board occur due to contamination of the contacts and tracks. Then the signal applied to the stop lamp can simply be redirected to the direction indicator lamp. This is radically solved by replacing the entire board with a new one, but the new bar will not last as long as we would like due to poor sealing of the ceiling from inside the luggage compartment. It seems to be a trifle, but we spend precious time on solving trifling problems that are solved at the production level with the right, and not VAZ approach.

Improvements and correction of factory errors

In the light of the foregoing, a breakdown of the electronics control unit is very typical for the nine. The reason is very simple - its body simply passes water, dust and moisture in the form of condensate. Its very placement on the air intake shelf is not entirely clear, but there are more significant disadvantages that can be eliminated with your own hands. The factory provided a tiny groove for water to drain from the case, but it constantly clogs, the case fills with water, and the control unit dies slowly and surely. It is not cheap, so such negligence of the designers defies explanation. There are two ways out of the situation - constantly clean the water drain channel, or change the block at least once a year.

It is also worth paying attention to the fact that the power wiring on the lower shelf of the radiator is constantly exposed to high temperatures. In addition, in this place it is not protected from water and dirt. It's also hard to explain. Wiring harness mishaps include a harness under the carpet next to the driver's seat. Moisture constantly accumulates there, and in order to remove it, you need to dry the floor, inevitably pulling this tourniquet. Of course, you cannot solve such a problem on your own - too much work on hauling all the wiring in the car.

It is worth paying special attention to the power terminals on the generator. They very often become loose, heat up, spark and melt the wiring. But this is not the worst. The wires can short-circuit, and here it already smells of burning. Therefore, do not be lazy, but as often as possible check this assembly for tightness of the terminals.

Wire Harness Insulation 2109

For the sake of isolating the harnesses, no one will disassemble half the car, but on occasion this must be done for your own safety. Using the diagram that we placed at the beginning of the article, all the work will not take much time, but you will be sure of the quality of the wiring insulation. For this you will need:

1. Corrugated hose for electrical wires.
2. Insulating tape.
3. Wire cleaner.

Before packing old wiring into a sleeve, treat the wires with a cleaner, which is sold in aerosol cans. Further, following the instructions and referring to the wiring diagram, we act as follows:

1. Disconnecting the battery
2. Disconnect the terminals and remove the harness.
3. We treat it with an aerosol.
4. We carry out a visual check of contacts.
5. We put the tourniquet in the corrugation.
6. We fix and seal the places where the harness enters the corrugation.
7. We lay the finished cable in place.
8. Referring to the diagram, connect the terminals.

Particular attention should be paid to sealing the harnesses in those places where they are in direct contact with water or hot surfaces. Also, when assembling, pay attention to the integrity of the pads and the condition of the contacts and terminals.

Thus, having spent quite a bit of time, we will save the wiring and get rid of unnecessary problems with short circuits. Follow the wiring, and good luck on the road!
