Contact ignition system. Wiring diagram "Six" for beginners: connection, maintenance and replacement Power circuit VAZ 2106

A typical wiring diagram of VAZ 2106 is made taking into account the single-wire principle of connecting the elements of the car electrical equipment. This means that minus contacts electronic devices Blind on the so-called. "Mass" vehicleAnd the wired connection provides only the positive conclusions.

Car wiring device

Such a principle for the integration of electronic components in the electric power supply of the car is in practice in such a form of compounds:

1. The active electrocups of the vehicle are activated by using the ignition switch.
2. Electronic devices that ensure the maintenance of the necessary degree of safety during the operation of the car are connected to the battery through the safety unit.
3. Cabinet parts of all the "Six" units are good current conductors.

Important: When carrying out repair and preventive work on the car you need to de-energize the wiring by removing the negative wire from the Accord terminal, otherwise the unauthorized touch of the battery contact tool can lead to KZ. For clarity, the email scheme. Wiring VAZ 2106 is posted on our Internet resource, and motorists can use it for the necessary tests.

With independent maintenance of the vehicle, it is necessary to determine the cause of one or another defect of the components of the gears electrical equipment. Troubleshooting should be started from the ignition switch, which is intended for:

• control of the functionality of the ignition system;
• coordination of the operation of systems for the protection and preventing car injects;
• towing "Six" with a working "accident".

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

• Akb with the contact of the negative wire on the body of the vehicle;
• starter with a "50" connector from the ignition switch through the start relay;
• generator device;
• safety unit;
• ignition switch;
• regulatory relay.

Principle of operation of electrical equipment VAZ 2106

The ignition switch has 4 positions, when excited each of which the switches of certain connectors and contacts are switched:

1. In the position "0", the battery current is broadcast only on the connectors 30 and 30/1, others are de-energized.
2. In the "I" position, the current is fed to the connectors 30-int and 30/1-15, while under the voltage are "dimensions", cleaner windshield, fan heating system of the heating complex.
3. In the position "II" to previously involved connectors, contact 30-50 is additionally connected. In this case, the ignition system, starter, panel sensors, "dimensions" and "turn signals" are included in the chain.
4. In the position of "III", only "dimensions", Klakson and wind and stern glass cleaners are involved. At the same time, the current is only available for connectors 30-int and 30/1.

A number of cars of this brand are equipped with such devices as a heating complex of feed glass, the electricer "Winder", light relay, etc. The power current to these gadgets comes along a separate line through the ignition switch at the key position "I" and "II".

Important: Because The washer 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, dielectric protection should be used on the connectors.

In the "six" under the current in constant mode, the following power supply chains are operating: Claxon, brake lights, "accidental", cigarette lighter socket, a plug for "carrying", dashboard. Lead chains electric equipment Transportation is to protect fuses of fuse-type, which are located in two special blocks (main and spare) located on the driver side under the dashboard.

One of the elements of the wiring scheme of the VAZ 2106 is a safety unit, the design of which does not satisfy the modern requirements for the content of electronic equipment. Disadvantages:

• the unstable connection of the fuse and the nest leads to the appearance of the storage facilities;
• when operating, the safety element is subject to heating, which negatively affects the attachment nests nearby;
• the low cost of replaceable fuses does not guarantee their reliability, so checking this block should be carried out regularly.

The use of the so-called. "Bugs" can entail the fire from the vehicle, because The likelihood of KZ is great. There is a completely safe version of the modernization of standard products, in which knife fuses are subject to installation, the seating places are perfectly integrated into the safety unit.

Advantages of knife fuses:

• sustainable contact of the product with a place of fastening;
• element of fusible type of smeared in the PVC- case of a transparent type;
• dynamic heat dissipation due to the increased area of \u200b\u200bcontact.

Important: Six generator device, wiring to it, as well as to the battery, starter, bobbine, optics and some other elements are not equipped with safety elements.

On vehicles VAZ 2106, the wiring diagram includes more than ten different components and modifications of the shared network. The car owner needs to be understood in this matter to repair and diagnose the power grid.

"Six" is equipped with a safety module, the designations of its components are shown below.

Video "Self-replacement of fuse pads"

The Ramanych user visually showed how to replace the blocks of safety elements on the "six".

As is known, the electrical chain in any vehicle is one of the main components. The electrical equipment scheme allows the driver of the VAZ 2106 to correctly detect the system malfunctions when the equipment fails is detected. This article is devoted to the wiring of domestic "six".

[Hide]

What is included in the power supply?

Regardless which ignition scheme in your VAZ 2106 is a contact or non-contact (BSZ), the vehicle electroscheme includes such components:

• rechargeable battery with minus contact on car body;
• starter device with output "50";
• the generator is one of the main elements of the VAZ 2106 electrical stroke;
• mounting block with fuses protecting the chains of power devices;
• ignition switch;
• regulator relay.

It should be noted that the electric pump of the car VAZ 2106 with BSZ or without it is initially made taking into account the single-wire type of connection of the components of the electrical equipment. In fact, this means that the negative contacts of electrical equipment are derived for a mass, that is, the body of the vehicle. As for the wired compound, it is provided exclusively to the positive wiring.

Detection of faults

If the VAZ 2106 has to look for a wiring fault during repair work It is necessary to completely de-energize the electricity. To do this, it will be necessary to disconnect the minus wire from the battery terminal, otherwise a short circuit may occur in the VAZ 2106 power grid. The damage diagnosis is detected using the scheme above.

If there are interruptions in the work, there are several versions of the car behavior:

1. The car can not move from the place and will not start. Reasons possible faults There may be many, but first of all it is necessary, the rubber, the performance of the AKB. As a rule, the full discharge of the battery is one of the most common causes. Much less often is the generator, but the diagnosis of this element on the VAZ 21062 with the BSZ should also pay attention to.
2. The machine moves, but one or more elements of the electrical circuits work incorrectly. For example, it may be failed in the work of light in the cabin, turning signals, heating the rear window or optics. If so, first of all it is necessary to check the fuse block and reveal the burnt elements. If all the fuses are whole, then in the case of optics, the performance of the lamps is first checked, after which the wiring translock of the VAZ 21063 machine is carried out with or without BSZ.

• manages all the possibilities of the ignition system;
• manages the operation of the security, as well as anti-theft systems VAZ 21063;
• allows you to train 21063 with light alarm (by video author - Andrey Aleksandrov).

The principle of operation of electrical equipment

The ignition lock at 21063 in accordance with the scheme has four modes, when you turn on each of which defined equipment is activated:

1. In mode 0, the pulse from the battery comes only to two connectors - 30 and 30/1, the remaining connectors are de-energized.
2. In mode 1, the pulse begins to be fed to other connectors, as a result of which dimensional lights, glass janitors, fan, and a device can work.
3. In mode 2, the operation of the ignition system is turned on, the sensors on the dashboard, swivel lights, as well as the starter.
4. In mode 3, only overall lights, steering beeps, as well as glass cleaners are operating.

In constant mode, the current in the model 21063 in accordance with the circuit operates the steering beep, brake lights, light alarm, backlight on the control panel, as well as the cigarette lighter. The main elements of the scheme are protected by fuses located mainly and additional blocks installed under the instrument panel opposite driver's seat (by video author - Vyacheslav Viter).

Diagnostics of faults

To properly replace the necessary elements of the circuit, when identifying faults, the following procedure should be performed.

Such actions are relevant if the car refuses to start:

1. Check the battery. Perhaps he just discharged.
2. First of all, a plot is checked on the diagram from the generator device to the coil. If there are breaks in the scheme, it is replaced and connecting new wires, oxidation - stripping contacts using an iron brush. If the contacts began to "draw", they are also subject to replacement.
3. Diagnose the coil for the presence of sparks. Remove the high-voltage cable from the installation site and bring it to the car body. When you try to start the motor, there should be a spark between high-voltake and the body.
4. Check if Ignition Candles workers. It happens that the reason for the impossibility of starting the engine is the net formed on the candles. You can easily clean them on your own, for this candle, you need to remove and use the instruction that you find here.

Weak Fuses Block Places

1. The poor compound of the fuse itself with the landing place, which leads to the burning of the nests.
2. During the operation of auto, the fuses are always warm, as a result of which they also negatively affect the nest located nearby.
3. The unit must be regularly checked, since the cost of the fuses is always low, and this corresponds to not particularly high quality of their execution and reliability.

Video "Damage for fuses at 2106"

Detailed designation of fuses on the "six" is described on the video below (by video author - avtoclub_22).

The main feature electrical circuit classic cars The VAZ family is single conduct. Those. All negative conclusions of nodes and appliances are directly connected to the "mass" of the car, in fact, the function of the second wire.

Thanks to this constructive solution, the wiring of VAZ 2106 is made as follows:

1. The main electric circuits of the car are activated only through the ignition lock;
2. Electrical mechanisms responsible for safety are connected directly to rechargeable batteryth through the fuse block;
3. The housings of all major vehicles of the car are conductive.

CAUTION: Be sure to remove the minus terminal from the battery whenever you take out one or another item.
Random touch with metal tools terminals and housing will lead to a short circuit.

Egnition lock

When servicing the car with their own hands, it is often necessary to figure out the reason for the failure of this or that electrical system .
It is best to search for failures to start from the ignition lock, since this device performs several functions in the car:

1. Is the control mechanism of the ignition system;
2. Performs the role of a security and anti-theft system;
3. Allows you to transport a car with an alarm enabled.

The scheme indicates:

1. Battery with connecting minus terminals for mass (car body);
2. Electric starter with output "50" from the ignition lock through the start relay;
3. Generator;
4. Fuse block;
5. Egnition lock;
6. Starting relay.

At the Ignition Castle 4, when activated which is activated, switching:

1. In the "0" position, the battery from the battery is served only on terminals 30 and 30/1. All other systems are disabled;
2. The "I" position is powered by terminal 30-int and 30/1-15. In this mode, only overall lights, windshield wiper, heater stove fan;
3. In the "II" position, the terminal 30-50 is added to the already connected. The ignition system, starter, instruments on the panel, overall lights and turns are activated;
4. In the "III" position, only overseas lights, beeps and wipers remain active. Power is supplied to the terminals 30-int and 30/1.

Additional (abnormal) devices and equipment

On some modifications of the car VAZ 2106 are set:

1. rear window heating system;
2. windshield washer equipped with electric drive;
3. middle Light Relay Plans.

Accordingly, that the wiring on the VAZ 2106 in such modifications is different. In particular, the power to these devices is supplied with a separate wire through the ignition lock. It can only be activated when the key is "I" and "II".

Reference: Since the washer tank is made of plastic, the electric motor receives a "minus" on the wire.
When replacing, do not forget to wear a protective plastic cover for contacts.

Features of the electrical network

In the car VAZ 2106 are constantly under voltage, regardless of the position of the key in the ignition lock:

1. Electrical chain of sound signals (claxon);
2. Stop signal incandescent lamps;
3. Alarm;
4. Cigarette lighter;
5. Plug socket for portable lamp;
6. Built in the ends of the front door of the backlight lamp.

Reference: The factory instruction informs that this is done specifically for freelance situations. For example, to prevent a possible accident, when the safety of people and vehicles depends on the threat rate.

Fleece fuses

The main electrical equipment of the car VAZ 2106 is protected by fuses.

They are connounced in blocks:

1. Main;
2. Additional;

And are located on the left side of the driver's seat under the instrument panel.

The diagram of numbers and arrows indicates:

1. castle drive lever on car hood;
2. main fuse block;
3. additional fuse block.

Reference: VAZ 2106 generator and wiring to it, as well as battery charge wire, starter, ignition coil, power supply relay far Light Headlights are not equipped with fuses.

The main fuse block on the VAZ 2106 is responsible for the safety of all electrical systems. And depending on technical features Their work depends the nominal resistance of the fuses.

Reference: If the current in one of the protected chains exceeds the permissible value, the safety thread melts and dispels the circuit. As a result, the wiring on the VAZ 2106, as well as the connected devices and devices will not be affected.

Additional fuse block protects:

1. chain on the cooling system fan electric motor;
2. chain of turning signs and alarm.

In each modern car There is an on-board network - a system connecting all consumers of energy and electrical equipment. These wiring devices are noted on, in particular, in this article we will discuss the legendary domestic "six". Which elements include the VAZ 2106 electrical stroke, which malfunctions are characteristic of it - find out from this material.

Signs of malfunction

What elements includes a scheme of electrical equipment and wiring with a description of 21063? This system includes all the energy consumers, as well as the main systems of the car, including ignition, engine cooling and heating. In the event that the machine does not start, while there are malfunctions in the work of electrical equipment, first of all, it should be checked with the health of the electrical wiring and replace the components failed.

If the engine is not possible, you should first diagnose the state of the battery, as well as the fuel supply to the carburetor or injector.

In the event that the fuel comes normally, then for the diagnosis you will need an electrical circuit of the machine, you need to check the following:

1. In case of carburetor engines Diagnostics of the ignition distributor, coils, candles, and, of course, the wiring itself is the connection of these components. In some cases, the impossibility of starting the engine is associated with damage to which the candles are connected.
2. In the event that we are talking about an injection force unit, then the reason may be in the inoperability of the ECM unit. This node is designed to process signals served from sensors, as well as transmit commands to actuators. In general, the control unit is intended to determine the most optimal parameters Motor works, but not all cars are equipped with them.

It also happens that the malfunction in the operation of the power unit is associated with the performance of the ignition lock, in particular, we are talking about damaged contact groups.

Carburetor Engine

How the carburetor motor electrical wiring circuit works when the power unit is started:

1. The driver turns the key in the ignition lock, while the system begins to feed the power to this node.
2. All indicators and badges are activated on the dashboard, in this case the equipment feeds from the battery.
3. A low voltage comes to the coil, which is used to form a high-voltage discharge. When the voltage passes through the module, it is converted to high-voltage and enters the distribution unit.
4. By means of high-voltage discharge, the drive of the distribution mechanism rotates the crankshaft of the "six" motor. Draver himself, in order of turn, makes a closure of contacts and transfers the discharge through high voltage wires on candles. Subsequently, this discharge is used to heat the combustible mixture in the motor cylinders (the author of the video is the Channel of the RF auto electrical).

Classic ignition

In accordance with the electrician circuit, the classic ignition includes such components:

• the castle itself;
• coil;
• rubber or distribution unit;
• high-voltage cables with candles.

Using a traver, an interruption of the primary winding of the module is interrupted, after which the high-voltage voltage is supplied in a certain sequence on the cylinders. As mentioned above, the coil is used to convert a low-voltage voltage to high-voltage.

In the event that when you try to start the engine, nothing happens, then the reasons may be such:

1. Damage to the wiring on the plot between the module and the generator node. With such a problem, you should diagnose the status of contacts, as well as the integrity of the electrical caps.
2. The failure of the coil itself. In this case, the operation of the device can be checked using a spark - a cable is retrieved from the distributor and comes into contact with the body or engine of the machine. If, when trying to start a motor, nothing happens, this suggests that the device is subject to replacement.
3. Damage to the wiring on the plot between the candles and the distributor. In this case, it is necessary to diagnose the state of the distributor cover, in particular, check the slider located inside, as well as the wires (author of the video - the channel Alexander AMOCHN Kolomna AAC).

Electronic ignition

VAZ 2106 cars also completed and electronic or contactless ignition (BSZ). A fundamental feature of such cars is that an electronic switch was additionally mounted between the distribution mechanism and the coil itself. In addition to the main components, BSZ includes a switching device, as well as a sensor distributor.

Using the latter, the control pulses are transferred to the switch device to create a spark, after which the signals are distributed over the cylinders. The main purpose of the switching device consists in converting control signals into a pulse voltage that is fed to the coil winding, in particular, we are talking about the primary winding. The presence of a switch contributes to improving the formation of a discharge, especially if the power unit operates on a depleted combustible mixture.

Injector Engine

As for injection force aggregates, such motors differ from the carburetor versions as follows:

• in the first there is an electric pump used to increase the pressure in the fuel system;
• the combustible mixture in this case is formed directly in the cylinder, while in carburetor versions Its formation occurs directly in the carburetor;
• in the injectors, fuel injectors are used, which provide a normal fuel injection;
• the presence, which makes it possible to accurately determine the moment at which the injection of a combustible mixture is needed (the author of the video is the channel tips to the motorist).

As you understand, injection power units Equipped with a large number of different sensors and controllers. Therefore, if the motor does not start, then the reason may be in trouble in the operation of the electrocups or the sensors themselves.

If we are talking about the sensor, then such a breakdown can be determined by your own hands:

• first, it is necessary to disconnect the wiring from the controller; the connector is retrieved;
• next, using the multimeter, the resistance is diagnosed;
• if the values \u200b\u200bobtained differ from normalized, then the device is most likely to be replaced.

Instructions for diagnosing and replacing wiring

Before proceeding with the replacement of wiring and failed components, it is necessary to diagnose the system.

How to check the tension:

1. For testing, you will need a lamp with wires, one of its dipsticks should be connected to the minus terminal of the battery or the "Six" bodies.
2. Another contact from the lamp connects to the diagnosed electrocups. It is necessary that the probe is as close as possible to the battery or a safety device.
3. In the event that the control as a result of the connection began to burn, this suggests that the voltage on the diagnostic area is available. Testing continues in a similar way until the damaged chain is detected. As practice shows, often faults in the operation of the electrical system are associated with a bad connection, therefore it is primarily recommended to check the contacts (the author of the video - the VAZ channel 2101-2107 repair and maintenance).

You can also check the integrity of the wiring, this is done in order to determine the discontinuity in electrocups.

To do this, do the following:

1. To begin with, turn off all the voltage from the electrical circuit and make it diagnostics for integrity. To do this, you can use a control lamp with a connected power source.
2. Both contacts from the lamp should be connected to the ends of the electrical circuit. If there is no such possibility, then one checklist is connected to the positive contact, and the other is connected to the ground, that is, the body of the car.
