VAZ 2106: fuses. VAZ 2106 fuse diagram

On VAZ-2106 cars, fuses were used of the old type, cylindrical. They protect electrical circuits, but the design has many disadvantages.

The location of the fuse box is good - near the driver’s left foot, away from moisture and direct sunlight. If we compare it with the VAZ-2109, in which the mounting block is located in the engine compartment, the six has a clear advantage.

Every VAZ-2106 owner needs to know which fuse protects which circuit.

Purpose of main unit fuses

The fuses are located on the main (upper) and additional (lower) ones:

1. F1, designed for a maximum current of 16 A, is necessary to protect the power circuits of the cigarette lighter, sound signal, interior lamps, clocks, brake lights, and light warnings about open doors.
2. F2, response current 8 A, allows you to protect the circuits of the windshield wiper and its relay, the electric washer motor and the heater.
3. F3, 8 Amperes, protects the power supply circuit of the left high beam headlight and the light control lamp.
4. F4, current 8 A, right headlight (high beam).
5. F5, F6, 8 Amperes – left and right headlights (low beam), respectively.
6. F7 – side lights (right rear and left front), light in the luggage compartment, license plate illumination, instrument cluster, cigarette lighter. Rated current 8 A.
7. F8 – side lights (left rear and right front), lamps under the hood and control panel on the dashboard.
8. F9 – designed to protect the power circuits of oil pressure, fluid temperature, gasoline level, and reserve lamp indicators. It also supplies power to the warning lamp, which signals that the handbrake has been applied, as well as an emergency level of brake fluid, a lack of battery charge, and the closing of the air damper. The XX solenoid valve, tachometer, reverse lamps, glove compartment lights, rear window defroster relay are also powered from this fuse.
9. Fuse F10 supplies power to the voltage regulator. Rating – 8 Amperes.
10. F11, F12, F13 – reserve.

Additional fuse block

1. F14 – fuse for protecting the power circuit of the rear window heater. Rated operating current 16 A.
2. F15 – electric motor for cooling the radiator. Current 16 A.
3. F16 – hazard warning lights and direction indicators.

Wiper relay and fuse

VAZ-2106 fuses protect power circuits by controlling electromagnetic relays. One of the main ones is the windshield wiper relay, which is powered through fuse F2.

With its help, the wipers do not work constantly, but intermittently. It is much more effective to control low-current circuits than power ones.

The relay is located under the dashboard, on the left side of the car interior. Replacement is carried out in this order:

1. Remove the seal on the driver's door pillar flange.
2. Pry up the upholstery and remove it.
3. Remove the holders installed on the side. Be sure to install new holders during installation.
4. Bend back the sound insulation.
5. Disconnect the block with the relay wires from the main harness. The connector is located at the bottom of the dashboard.
6. Remove the two screws that secure the relay housing to the body.

After removing the old relay, install a new one in its place. The work is performed in reverse order. If replacing the VAZ-2106 fuses responsible for the operation of the windshield wiper did not help, then be sure to check the integrity of the wires and relays.

Direction indicators and hazard warning lights

There is one drawback in the car - the VAZ-2106 fuses are located in the passenger compartment, but the relays are scattered throughout the engine compartment. The breaker responsible for the operation of the direction indicators is located on the partition in the engine compartment opposite the dashboard. Main breakdowns of the alarm system:

1. Fuse F16 is faulty. Check it with a multimeter and replace if necessary.
2. Frequent turning on of the control lamp indicates that one of the repeaters or indicators is faulty.
3. A relay malfunction leads to complete failure of the warning system.
4. If the alarm button breaks down, it does not allow the indicators to turn on.

To replace, you need to remove the instrument panel, then unscrew the nut using a 10mm socket. After this, disconnect the wire block and remove the relay. Install the new one in reverse order.

Turning on the headlights

To turn on the high and low beams, two relays are used, which are installed in the engine compartment, above the right mudguard. Removing the relay is very simple - just disconnect all the wires from it and unscrew the self-tapping screw with a Phillips screwdriver. Together with the bracket, the end of the ground wire is also attached to the body with a self-tapping screw.

Be sure to mark the location of the wires before disconnecting them from the electromagnetic relay. You can disconnect the wires one at a time and immediately install them on a new relay.

The replacement procedure is simple, so it can be completed in a few minutes. If the relay does not receive voltage, then the fuse links need to be replaced.

In the VAZ-2106 fuse circuit, elements F3-F7 are used to protect the power circuits of the low and high beam lamps.

Turns relay

An indicator breaker with 3 or 4 contacts is located behind the instrument panel on the partition of the engine compartment. The rating of the light bulbs connected to the circuit should be 21 A. It looks like a rectangle.

Generator fuse and relay diagram

To check the condition, you need to get to the thermostat, since it is located directly below it. It is attached to the generator with two screws and connected with a wire that often frays. This is true for the VAZ 2106 modification with an injector. Without it, the power supply to the generator excitation winding will be unstable.

Starter relay

You can easily find the retractor, as well as remove it yourself. You need to disassemble the starter using screwdrivers. You will need to correctly install a new one in its place.

High and low beam fuse and relay

The elements F5 and F6 are responsible for the first one, and F3 and F4 are responsible for the distant one. The power of each is 8 A.

Handbrake relay VAZ 2106: where is it located

On the parking brake.

Tachometer

It is protected by fuse F9 rated 8 A.

Radio tape recorder

It is connected to one of the backup fuses.

Washer

The protective element is marked F2 and is rated at 8 A.

Distributor

Can be found near his slider at the top.

Parking brake

The relay is located behind the dashboard of the VAZ 2106, has a round shape and is made of aluminum.

Fuse F1

If the interior lighting or socket does not work, the 16 Amp fuse element that is responsible for them may have burned out.

One of the high beam lamps has burned out

With such a malfunction, the high beam does not fail completely - as a rule, only one lamp turns off. Almost every car owner knows the solution to the problem in this case, but we will still remind you how to make a replacement:

• Unscrew the bolts securing the rim of the faulty headlight
• Turn the glass clockwise and pull the headlight out of the housing
• Disconnect wires from contacts
• Press the latch and carefully remove the light bulb

You can verify that the lamp is faulty by examining the filament (as is the case with ordinary household lamps). If the lamp is faulty, you need to purchase a new lamp and install it in place of the old one, without touching the glass with your hands. After that, reassemble everything in reverse order and make sure the high beam is working.

The “six” light acquires special importance when a motorist has to drive in conditions of poor visibility, in difficult weather conditions and at night. However, any driver must remember that defects in the vehicle’s electrical equipment system, one way or another, affect the functionality of the power plant. And this is despite the fact that the main electrical circuits are protected by relay elements, just as the lighting of the “six” is protected, the safety devices of which are routed to the vehicle’s fuse box.

On the VAZ 2106, the headlight relays, along with other main electrical equipment of this vehicle with high current consumption and high voltage, are connected via relay elements. The main purpose of the VAZ 2106 light relays, whose price is low, is to protect the switch contacts from energy overload.

Car enthusiasts often ask where the high and low beam relays are located on the “six” and what they look like. Let us explain that almost all relay devices, as well as the relay - voltage regulator, are located in the power plant compartment. The exception is the turn signal and hazard warning relays, which are located under the instrument cluster in the car interior, covered by a front panel. Both relays are identical in appearance (they can be easily found on the mudguard on the right as the car moves) and are located next to the battery charging indicator relay.

The electrical diagram of the light relay is located below:

On the general diagram of the electrical equipment of the “six” you can see at number 5 the VAZ 2106 low beam relay, and at number 6 the VAZ 2106 high beam relay, which are interchangeable elements. Also here you can see the integration of the main electronic devices of the vehicle into the general electrical supply circuit of the vehicle of this modification.

Relay for high and low beam "six"

As already mentioned, the standard high and low beam relays of the VAZ 2106 are absolutely identical, have similar catalog numbers (90.3747-10 or 113.3747-10), are of the same type as the initiation relay for the radiator fan device of the cooling complex of the power plant and can be replaced with each other friend.

To connect the light relay to the VAZ 2106, devices with item number 113.3747 are used, which are installed in a mounting-type block device. Similar devices are installed in the system to turn on the EDC fan device, heat the stern glass and produce alarm sounds.

The initiation voltage of the device at an average temperature of about 23 °C is within 8 V, and the resistance of the device winding at a temperature of 20 °C is 85 ± 8.5 Ohms.

Instead of products under catalog number 113.3747, it is allowed to use updated high and low beam relays VAZ 2106 90.3747-11 in a plastic case and with increased dimensions. It is also allowed to replace products 113.3747-10 with a mounting bracket with gadgets with fasteners under the nomenclature value 90.3747-10 with the same characteristics.

The automotive industry practices the production of light relays for the VAZ 2106 under the nomenclature numbers 902.3747 (version 11 - without fasteners and 10 - with fasteners), used on injection "sixes", because The device integrates an additional resistance to suppress interference, connected in parallel to the relay winding. For such high and low beam relays, the resistance between connectors “85” and “86” is 65 - 80 Ohms. They are interchangeable with the VAZ 2106 light relay

Additional fuse block

1. F14 – fuse for protecting the power circuit of the rear window heater. Rated operating current 16 A.
2. F15 – electric motor for cooling the radiator. Current 16 A.
3. F16 – hazard warning lights and direction indicators.

When connecting a new unit, be sure to use the VAZ-2106 fuse diagram. This will prevent the elements from being mixed up.

How does a standard six fuse work?

Let's consider the design and operating principle of a standard “six” fuse-link. Unlike a modern knife fuse, it consists of only two parts: a ribbed plastic cylinder that acts as a body, and the insert itself, made of low-melting metal, located outside it. The contacts of the VAZ-2106 mounting block are made of copper (brass) and also have an open arrangement. From the point of view of electrical engineering, such a design cannot be called either reliable or safe, since all conductive elements, in fact, are not protected in any way.

Fuse box problems and troubleshooting

On the VAZ "six" fuses are installed in two blocks - the main and additional ones. Structurally, they are made of a plastic case, fusible inserts and holders for them.

VAZ 2106 fuse blocks: 1 - main fuse block; 2 - additional fuse block; F1 - F16 - fuses

Both devices are located in the cabin to the left of the steering column under the dashboard.

The fuse box on the VAZ 2106 is installed to the left of the steering column under the dashboard

How to identify a blown fuse

When a “six” has a malfunction with one of the electrical appliances (windshield wipers, heater fan, etc.), the first thing you should pay attention to is the integrity of the fuse links. Their serviceability can be checked in the following ways:

• visually;
• multimeter.

Visual inspection

The design of the fuses is such that the condition of the fuse link can be used to determine the operability of the part. The cylindrical elements have a fusible connection located outside the housing. Even a car enthusiast without experience can determine its destruction. As for the flag fuses, their condition can be assessed by looking through the light. A burnt-out element will have a broken fusible link.

Determining the integrity of the blade fuse is quite simple, since the element has a transparent body

Diagnostics with a control and a multimeter

Using a digital multimeter, the functionality of the fuse can be checked by voltage and resistance. Let's consider the first diagnostic option:

1. We select a limit on the device to check the voltage.
2. We turn on the circuit being diagnosed (lighting devices, wipers, etc.).
3. We touch the fuse contacts one by one with the probes of the device or control panel. If there is no voltage at one of the terminals, it means that the element being tested has failed.

Subtleties and nuances that a car enthusiast should know about

• The location and number of the module is indicated on the power supply cover;
• Before replacing a module, check the equipment connected to it for serviceability;
• If the module is intact and the equipment is working properly, but no current is flowing, there is most likely damage in the electrical supply circuit;
• The ignition and electric fan motor activation relays are not protected by fuses;
• If you install one with a lower rated current instead of the original module, then most likely the fuse link will burn out. This is not a defect, but a sign that the voltage readings do not correspond;
• Installing a module with a high rated current will increase the likelihood of failure of the equipment assigned to this module;
• It is strictly forbidden to use foil as a conductor instead of a power supply;
• If a fuse with a similar amperage blows at the same time, then there are big problems with voltage in the system. Contact a service station for diagnostic work.

VAZ 2106 fuse box pinout, diagram

If you have any problems with electrical equipment: the low or high beams have disappeared or are not working, the turn signals, stove, cigarette lighter, fan, wipers are not working, the signal has disappeared, etc., then this could all be the reason that the fuse has blown. This means it needs to be replaced.

To do this, you need to know the location of the mounting block. And it is located under the steering wheel, on the left side. In order to understand what the VAZ 2106 fuses are responsible for, you need to look at the simple pinout of the old fuse block (FB) and see the description below.

Below is a picture of what the Eurobloc looks like in real life.

Replacing the VAZ 2106 fuse box with a “Euroblock”

And finally, for those who don’t know how to replace the old model with a “Euroblock”, the following information. There is nothing complicated here.

You just need to follow the instructions below:

1. First you need to disconnect the minus from the battery.
2. Use a 10mm wrench to unscrew the old power supply. In this case, the wires are not disconnected.
3. According to the diagram above, wires and jumpers are installed.
4. It is important to install jumpers only on those wires that carry voltage from the engine compartment.
5. Jumpers are installed between pins 3-4, 5-6, 7-8, 9-10, 11-12.
6. Next, the wires are removed one by one from the old device and attached to the Euroblock.
7. At the end, check that the connection is correct (for example, with the low beam on, if you pull out the 5th fuse, the left headlight should go out).
8. All other circuits are also checked.

The video below clearly shows how to replace an old power supply with a Euroblock.

Removal and replacement process

There is nothing difficult in the process of changing power supply parts, so we will not describe this process. But we will tell you how to replace an old-style power supply with a new-style device.

1. First of all, disconnect the battery. Now open the driver's door and use a screwdriver to pry out the two fasteners securing the decorative interior trim. Move it to the side and you will see a block. Using a Phillips screwdriver, unscrew the screws securing the power supply. Do this carefully so that the wires do not fly off the terminals in the process.
2. Once the power supply is unscrewed, move it down. But do not pull it too hard to avoid breaking the wires. Note! Jumpers must be installed on those wires through which voltage comes from the engine compartment. Do not connect the jumper after the fuse itself, otherwise this will result in voltage passing through one part to power several electrical components.
3. The order of installation of jumpers should be as follows: 3-4, 5-6, 7-8, 9-10, 11-12, 12-13.
4. Now you need to remove each wire one by one, starting with the first fuse from the old power supply, and mount it on the new one. Perform this operation with each contact, until the very last wire. When all the contacts are in place, you should check whether you did everything correctly. In particular, you need to turn on the voltage source and remove the corresponding fuse. If the device stops functioning, then all actions were performed correctly. For example, turn on the low beam headlights and remove one of the power supply elements responsible for the left or right headlight. If it goes out, then you did everything right.
5. Check each fuse in the same way. If, when dismantling the element, the device continues to work, then the jumper is most likely installed incorrectly, so double-check the connection diagram.

This completes the replacement of the power supply with a new type device. As you can see, there is nothing difficult about this, but if you are not sure that you will do everything correctly or cannot distinguish the blue wire from the red or green, then entrust this matter to an electrician.

Location and electrical diagram

The power supply itself consists of two lines with fuses, which is installed in the car interior and attached to the body with two nuts. In particular, it is located on the driver's side under the instrument panel. Below is a diagram of the device, as well as the purpose of each element.

As you can see, almost all circuits of a domestically produced car are protected using fusible devices. However, there are exceptions here too. In particular, we are talking about:

• starter retractor relay - it is missing;
• the power circuit of the relay coil, which ensures the operation of the radiator fan of the cooling system, is also not protected;
• the ignition coil is also not protected by a relay;
• If your car has an old-style power supply, then it does not have a power supply circuit for the switch and a Hall sensor.

The element installed in the power supply is designed for a certain voltage in the wiring. This voltage is calculated using a simple formula - the voltage of all energy consumers in the wire must be multiplied by the reserve number, ranging from 1.2 to 1.5. So what's the purpose? In order for the operation to be stable, the nominal values ​​of the block elements must match.

It should be added that very often owners of 2106 make mistakes by using an ordinary coin instead of a fusible device. It is better not to do this, since a short circuit may occur in your car at any time. Therefore, old-style power supplies, like any other machine component, also require periodic maintenance. Due to design features, that is, weak power supply holders or tips that regularly oxidize, you may notice the contact part burning.

Thus, due to the increased contact resistance, overheating occurs and the contact condition of the element deteriorates. This may result in additional problems with the vehicle's wiring. To prevent this from happening, you should periodically, at least twice a year, inspect the power supply unit as a whole. Clean the mounting sockets, inspect the power supply and promptly replace failed fuses.

But this all applies to old-style power supplies. Some owners of these car models, taking into account the periodic problems with the old-style power supply, change it to a new one.
