The electrical circuit of the vaz. Schemes of electrical equipment LADA Samara Basic principle of operation of electrical equipment

A typical wiring diagram for the VAZ 2106 is made taking into account the single-wire principle of connecting elements of the vehicle's electrical equipment. This means that the negative contacts of electronic devices are brought to the so-called. "mass" of the vehicle, and the wired connection provides only positive terminals.

Vehicle wiring device

This principle of integrating electronic components into the electrical circuit of a car is put into practice in the following form of connections:

1. The operating electrical circuits of the vehicle are activated by using the ignition switch.
2. Electronic devices that ensure the maintenance of the required degree of safety during vehicle operation are connected to the battery through a safety block.
3. The body parts of all the six units are good current conductors.

Important: when carrying out maintenance and repair work on a car, it is necessary to de-energize the electrical wiring by removing the negative wire from the battery terminal, otherwise unauthorized touching of the battery contact with the tool may lead to a short circuit. For clarity, the diagram e. VAZ 2106 wiring is posted on our Internet resource, and motorists can use it to conduct the necessary tests.

With self-maintenance of the vehicle, it is necessary to determine the cause of a defect in the electrical components of the "six". Troubleshooting should begin with the ignition switch, which is designed to:

• management of the functionality of the ignition system;
• coordinating the work of security systems and preventing car theft;
• towing "six" with a working "emergency gang".

In a VAZ 2106 car, the wiring diagram includes the following elements:

• Battery with a negative wire contact on the vehicle body;
• starter with connector "50" from the ignition switch through the start relay;
• generating device;
• safety block;
• ignition switch;
• control relay.

The principle of operation of electrical equipment VAZ 2106

The ignition switch has 4 positions, when each of them is activated, certain connectors and contacts are switched:

1. In the "0" position, the battery current is transmitted only to connectors 30 and 30/1, the others are de-energized.
2. In the “I” position, the current is supplied to the connectors 30-INT and 30/1-15, while the “dimensions”, the windshield wiper, the fan heating system of the heating complex are under voltage.
3. In position "II", contact 30-50 is additionally connected to the previously used connectors. In this case, the ignition system, starter, panel sensors, "dimensions" and "turn signals" are included in the circuit.
4. In position "III", only the "dimensions", the horn and the windshield and rear window wipers are activated. In this case, the current is available only to the 30-INT and 30/1 connectors.

A number of cars of this brand are equipped with such devices as a heating system for the rear window, an electric windshield washer, a light relay, etc. The power supply to these gadgets is supplied through a separate line through the ignition switch at key positions "I" and "II".

Important: because Since the washing tank is made of PVC material and is a dielectric, the electric motor is additionally equipped with a negative wire and when working with it, it is necessary to use dielectric protection on the connectors.

In the "six" under current, the following power circuits operate in a constant mode: a horn, brake lights, an emergency gang, a cigarette lighter socket, a "carrying" plug, and instrument lighting. The leading circuits of the electrical equipment of the transport are subject to protection by fuses, which are located in two special blocks (main and spare) located on the driver's side under the dashboard.

One of the elements of the VAZ 2106 wiring diagram is a safety block, the design of which does not meet modern requirements for the maintenance of electronic equipment. Flaws:

• unstable connection of the fuse and the socket leads to the appearance of burning places;
• during operation, the safety element is subject to heating, which negatively affects the nearby mounting sockets;
• the low cost of replacement fuses does not guarantee their reliability, so checks on this unit should be carried out regularly.

The use of the so-called. "bugs" can lead to a vehicle fire, because. there is a high probability of a short circuit. There is a completely safe option for upgrading standard products, in which blade fuses are to be installed, the seats of which are perfectly integrated into the fuse block.

Benefits of knife fuses:

• stable contact of the product with the place of attachment;
• the fusible type element is sealed in a transparent PVC case;
• dynamic heat dissipation due to the increased contact area.

Important: the “six” generator device, the wiring to it, as well as to the battery, starter, bobbin, optics switching relay and some other elements are not equipped with safety elements.

The VAZ-2106 model car began to be produced in 1976. It differed from its predecessor VAZ-2103 by a more powerful engine, the volume of which is 1.6 liters, a modified body and interior. At the time of its publication, it was the most prestigious and comfortable car. Below is a high-quality color diagram of the electrical equipment of a domestic VAZ-2106 passenger car. As with any machine, this model may experience electrical malfunctions, so the electrical circuit will be indispensable for identifying and eliminating such problems. With its help, you can find out exactly where the breakdown occurred in the electrical circuit and make the appropriate repair. You can find out which lamp on the instrument panel or headlight is not working, which sensor is out of order, repair the generator, check the fuses, and other repair actions based on the information provided.

It is important not only to keep the contact groups clean, but also to use fuses of the rating recommended by the manufacturer. Ignoring these requirements threatens the failure of electrical equipment.

The electrical equipment of the entire LADA Samara family, as well as Samara-2, has the same circuit as a whole, differing only in nuances. This applies to both cars with carburetor and injection engines. The injection engine ECM is not connected to the common wiring, therefore it does not depend on it.

All the diagrams below show a carburetor ignition system, but you don’t need to be scared: there are simply no “carburetor” elements on injection machines, and the ECM is connected separately with its own connection to the battery and is not connected in any way with the main circuit of the car.

This wiring diagram is presented in the best quality. In fact, this the most up-to-date scheme of the VAZ-2108 (09) remaining in operation. The circuit is also interesting in the presence of an internal circuit of the mounting block.

All the diagrams do not make any reservations about the option of the mounting block, so with a high probability they are interchangeable. But there may be minor non-critical discrepancies, which most likely will not affect the operation.

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 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 a 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 switch

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!
