regul. pauses "Energomash"

Windshield wiper breaker with pause adjustment 722.3777-02.

1 Installing the windshield wiper switch.

1.1 Disconnect the wiring harness from the steering column wiper switch by opening the 6-pin connector, which is located behind the instrument panel or inside the steering column housing. 1.2 Connect the terminal blocks of the windshield wiper breaker into the resulting gap in the harness. 1.3 Using a connector, connect the free wire of the breaker to the wire connecting the steering column switch to the washer motor. This is one of the wires of the 2-pin block of the steering column switch, the potential of which, when the washer is turned on, changes from +12 V to 0 V or vice versa (depending on the specific brand of car). 1.4 Using the breaker mounting hole, install it in a convenient place on the car. The windshield wiper switch is ready to operate.

2 Pause adjustment.

2.1 Set the windshield wiper mode switch to the “Intermittent mode” position - the standard pause of the windshield wiper operation will be set (about 5 seconds between sweeps of the blades). 2.2 To change the pause, move the switch to the “Off” position and, after maintaining the required pause, switch to the “Intermittent mode” position. The new pause value will be set. The pause range is from 0.5 to 45 seconds. 2.3 The pause can also be changed in another way: move the switch to the “Continuous mode” position and, during the first stroke of the brushes, back to the “Intermittent mode” position. The pause value will be equal to the time interval from the last stroke of the brushes until the moment of switching to the “Continuous mode” position. The pause can be changed at any time by repeating step 2.2 or 2.3.

3 Other modes.

3.1 When water is supplied, the movement of the brushes begins with a delay of 0.5 seconds (allows a sufficient amount of water to accumulate on the windshield before the first stroke of the brushes).

3.2 After supplying water, the brushes make three strokes.

We present to your attention the electrical circuits of equipment for the VAZ-1111, also known as OKA, 1988-2003. 4-seater hatchback of a particularly small class with a transverse engine and front-wheel drive. Production of the Oka began in 1989 at the Volzhsky Automobile Plant. The engine is a two-cylinder with a displacement of 650 cc, in 1997 it was increased to 750 cc. volume. Currently, the production of Oka cars has been transferred to the Kama Automobile Plant, as well as the Serpukhov Automobile Plant. In addition to the basic models KamAZ-11113 and SeAZ-11113, manual control options are available for disabled people. Due to its very low price, it is of interest for export. This small car was developed at the Volzhsky Automobile Production Plant at three factories - VAZ, KamAZ and SeAZ - in a disabled version, and has been produced since 1990.

Division by function

As for functions, all electrical equipment is divided into systems that perform specific tasks:

• Take part in the operation of the engine;
• Ensure traffic safety;
• Create comfortable conditions;

There are also systems that are aimed at maintaining the functionality of the electrical circuit itself.

Systems responsible for engine operation

The ignition system takes part in the operation of the power unit and its task is to generate a spark in the engine cylinders to ignite the air-fuel mixture. The components of this system are a switch, a spark torque sensor, a coil and spark plugs. The system is turned on using the ignition switch. All of these components are connected by one circuit, the diagram of which is shown below:

The second system related to electrical equipment and working with the engine is the starting system. To start the engine, a power electric motor is used - a starter, controlled from the same ignition switch. Its scheme is as follows:

The cooling system fan is also related to the engine.

Systems responsible for safety and comfort

Electrical equipment that ensures traffic safety includes:

• Light and sound alarm (turn signals, brake lights, reversing lights, sound signal);
• Main light (headlights, PTF);
• Heaters, glass cleaners and washers;

These devices are combined into several systems. Below is the power supply diagram for only one of them - the turn signals:

Since the Oka is a budget car, there are not so many electrical appliances that create comfortable conditions for the driver. These include a stove (which includes an electric fan motor), an interior lamp and a cigarette lighter.

Note that the stove, in addition to creating convenience, also affects traffic safety - it heats the windows in winter.

Since devices responsible for traffic safety and comfort are not always in demand, they are turned off by default and are activated using switches.

The on-board network also includes a battery recharging system, that is, a component whose task is to maintain the functionality of electrical equipment. Its connection diagram is as follows:

Electrical equipment Oka

The VAZ-1111 and 11113 Oka are equipped with all the necessary electrical equipment necessary to ensure traffic safety and create minimally comfortable conditions for the driver and passengers. All electrical appliances installed on a small car are connected by a single electrical network.

The on-board network used on Oka is 12-volt, DC, single-wire. The role of the second wire is performed by the car body and a number of components and mechanisms - the power plant, gearbox.

Preventive measures

The main measures to ensure reliable operation of the electrics of Oka cars:

1. At least once every six months, clean the outer part of the battery case and check the electrolyte level (on serviced models). At the same time, it is necessary to recharge the battery using a special device. If the vehicle is rarely used, it is recommended to disconnect the terminals.
2. When carrying out repair work, you should monitor the position of the wires, avoiding damage to the insulating layer. Wires passing near moving elements must not come into contact with them under any circumstances.
3. It is not recommended to turn on devices with high current consumption (audio system, high beam headlights, etc.) with the engine off. This will cause the battery to drain faster.
4. Do not use homemade elements to repair electrical circuits. All used parts and assemblies must comply with the standards laid down by the designer when developing the car.
5. It is recommended to carry spare fuses, relays and lamps with you. This will allow you to make minor repairs if necessary.
6. When carrying out repair work that requires the use of welding, it is necessary to disconnect the harnesses from the battery and generator. On machines equipped with an injection engine, it is recommended to disconnect the connector from the control unit.

How to identify a blown fuse

It is quite simple to assess the condition of cylindrical type modules, as well as knife type ones. In both cases, a melting element is laid in the center of the fuse.

As soon as the current exceeds the permissible value, the plate instantly melts, opening the contacts. A small black spot forms, which is evidence that the part is faulty.

The module is removed from its seat using special plastic tweezers. In life, an accessory is often lost, so it is practiced with your fingers. After replacement, we put the power terminals on the battery, start the engine, and test the system.

Lamp burned out

Naturally, if any light source does not turn on, the first thing that comes to mind is that the light bulb has burned out. The design of car lamps is such that the low beam may indeed be absent, but the high beam remains available. Halogen lamps have two filaments. It is quite possible for one of them to rupture - in this case, the light for which it is responsible will be absent.

To replace the bulb, the services of an auto electrician are not required. It is enough to open the hood with the ignition off, remove the protective box on both sides of the headlight, pull out the contact group, disconnect the spring clips, remove the burnt out bulb and install a new one.

A little subtlety:

The flask should be wiped with alcohol before installation, otherwise it will burn instantly. It is also not recommended to handle the bulb with unprotected hands: there is always some greasy and damp secretions on them, which can damage the light bulb. The best way to do this (replace the lighting) is with a dry cloth or rag.

For ease of maintenance and troubleshooting, the wiring connecting the components of electrical equipment is color coded. Connecting devices to wires is carried out in different ways - through blocks, clamping with nuts, using sockets (light bulbs). In all cases, disconnecting the wiring is easy and does not particularly complicate the dismantling of electrical appliances during maintenance.

An electrical circuit combines all components related to electrical equipment. All components can be divided among themselves according to two criteria:

• Purpose;
• Functions performed;

Peculiarity. An electrical circuit is the interweaving of certain sections of power circuits, especially the fuse box. That is, one fuse may be responsible for the operation of electrical appliances that do not interact with each other in any way.

Fuse installation diagram

The cost of the original fuse block assembly (hereinafter referred to as the BP) starts from 1,200 rubles. high-quality analogues from 800 rubles.

Disassembly

Disassembling the generator, in general, is not difficult, with the exception of one point - removing the pulley. You can fix the rotor in order to loosen the pulley fastening nut using a special tool. device An alternative removal option is to fix the pulley itself in a vice using elastic attachments (for example, a belt can be placed between the pulley and the jaws).

The general operating technology of the generator is as follows:

• Remove the pulley (using a tool or a vice);
• Disconnect the capacitor wire and dismantle the capacitor itself;

• Unscrew the regulator mount and remove it;
• Unscrew the coupling bolts;
• Use a puller to tighten the front cover;

• Remove the rotor;
• Unscrew the fasteners of the stator leads to the rectifier;
• Remove the stator;
• Unscrew the nuts securing the rectifier to the back cover;
• Remove the rectifier;

After disassembly, all that remains is to remove the front bearing, which is installed in the front cover, for which you need to unscrew the bolts holding the fastening washers together.

Having finished disassembling, we clean all parts and troubleshoot. Some types of faults can be determined visually, but for such faults as breaks and short circuits of the windings, the Oka generator needs to be checked using measuring instruments. For example, to test the regulator, you need a charger with regulated voltage.

This component is checked like this:

• We connect a charger to the output and ground of the regulator, and a 12-volt light bulb (control) to the brushes;
• We apply a voltage of 12 volts, and the lamp should light up;
• We increase the voltage to 15 V (in a working regulator the control should go out);

If the lamp does not light up at 12 V or does not go out at 15 V, the regulator is faulty and requires replacement. As for the stator windings, it is better to entrust their inspection to an experienced auto electrician.

Assembly of the unit is carried out in reverse order

In this case, special attention should be paid to the correct connection of the generator, or rather all its terminals and wires

If an auto electrician determines that the device cannot be repaired, it will have to be replaced with a new one. And what makes the generator suitable for Oka is indicated above.

Common electrical faults

Common problems with electrical equipment on VAZ-1111 and 1113:

1. Failure of external lighting devices. A common cause of failure is burnt out lamp filament; the unit must be replaced. If the light bulb is intact, then there may be a defect in the electrical wiring, due to which a short circuit occurs and the fuse fails. The fuse link is replaced with an identical one; it is prohibited to use parts designed for a higher current. It is also unacceptable to install homemade jumpers (“bugs”), as this can cause a fire. If a repeated burnout occurs, it is necessary to check the circuit and eliminate the wiring fault.
2. Wire breaks occur at points where the insulation is subject to bending or friction against moving surfaces. An example of such a point is the junction of the door and the body. Damaged areas must be replaced with products made of similar material with an identical cross-section.
3. Oxidation of contact surfaces due to moisture or aggressive liquids (for example, battery electrolyte). It is necessary to clean the surfaces down to metal, restoring the transmission of electric current.
4. Relay failure associated with burnt contacts or coil breakage. The unit cannot be repaired; it must be replaced with a new one. In the event of a rapid re-failure, the vehicle's electrical system must be checked at a car service center.
5. Sudden battery discharge is due to an internal short or current leakage. In winter, a partially charged battery may lose capacity due to low air temperatures. You need to charge the battery and check the condition of the wiring. If necessary, the power source must be replaced.
6. Pulsating operation of external lighting lamps with an unusually bright glow indicates a breakdown of the relay regulator on the generator. Repair requires removing the unit and replacing failed components.
7. Insufficient battery charge (the warning light does not go out when the engine is running). The cause may be wear on the brushes or commutator, or insufficient tension on the drive belt. The generator needs to be repaired, since the battery charge is enough for 150-200 km during the daytime.
8. Poor contact between the ends of the cylindrical fuses and the spring-loaded elements in the mounting block. It arises due to the design features of the unit. Many owners, tired of dealing with the defect, install homemade blocks for knife inserts. Usually a short section from the GAZ-3110 is used, designed for 13 seats. There are self-assembled units designed for fuses and relays.

Replacing fuses on Oka

The PSU installation process is quite simple and intuitive. At the preparation stage, we check the availability of:

• Collar;
• Heads on "10";
• A new old-style power supply unit (cylindrical type) or a knife type, if the owner decided to upgrade;
• Additional lighting as needed if work is carried out in conditions of limited visibility.

• Place the car on a flat surface, open the driver's door wide;
• We wedge the rear row of wheels with wheel chocks and squeeze the parking brake lever. This is necessary for personal safety during work;
• Open the hood, unscrew the power terminals from the battery to prevent a short circuit in the on-board circuit;
• We snap off the cover from the power supply unit and squeeze the plastic clips on the sides;
• Using a 10mm socket, unscrew the mounting bolts on the sides. We remove the power supply from the seat.

Main malfunctions and why the starter does not turn?

Malfunctions of the Oka starter, as well as the power electric motors of cars, are divided into two categories - mechanical and electrical. The first includes:

• Wear of armature support bushings;
• Damage to gear teeth;
• Jamming of the retractor relay armature;
• Development of splines for the armature shaft;

The most common mechanical failure is wear of the support bushings, which subsequently becomes the cause of other breakdowns. Due to significant wear of the bushings, the position of the armature and, accordingly, the bendix are disrupted. As a result, it is more difficult for the gear to engage, the wear rate of the teeth increases, and they may crumble.

Electrical faults include:

• Breakage of stator windings, armature, solenoid relay;
• Heavy wear of collector plates;
• Critical wear of brushes;
• Closing the windings;
• Burning of “nickels” of power contacts;

To this category of breakdowns you can also add problems with the power circuits of the electric motor and relay.

Turn relay VAZ 2101

Malfunctions of the Oka starter manifest themselves in different ways:

• The starter does not turn on, there are no additional sounds;
• You can hear the activation of the solenoid relay, but the electric motor does not turn;
• The starter rotates, but picks up speed;
• Extraneous sounds are heard when turned on (crunching, grinding);

If such signs occur, the unit should be repaired.

All about the features of Nissan x-trail fuses: photos and videos

Like any internal combustion engines of passenger vehicles, the power units of the Oka car modifications 1111, 11113 are started using a starter - a power electric motor with remote control. The task of this unit is to spin the crankshaft to create the necessary conditions for ignition of the air-fuel mixture.

Models, characteristics, location

The designers did not borrow a starter from other VAZ models, but made a new one - for Oka engines. The impossibility of unifying starters for owners of this small car often results in problems, since the “native” starter is not a particularly reliable unit.

It is noteworthy that Oka’s power electric motors were produced by several manufacturers. The most common is the unit with the factory index 39.3708 (KZATE Samara plant), which we will consider in the future. Also, the VAZ-1111 was equipped with Belarusian-made components (1111-3708010-5) and Slovenian ones - AZE-1517.

The main characteristics of model 39.3708 are as follows:

• Power – 0.9 kW;
• Current consumption – 230A;
• Weight – 5 kg;

This unit is mounted on the left side of the engine (in the direction of travel) above the gearbox, and the thermostat housing is located above it. Fixation is carried out with only two fasteners - a bolt and a nut, with which the starter is attracted to the clutch housing. This arrangement is convenient because you can dismantle the unit from the car without removing anything additional.

The starter on the Oka is a commutator electric DC motor. Its main components are:

• Stator with field windings;
• Brush holder (brush assembly) with 4 graphite brushes;
• Anchor;
• Bendix (drive gear with freewheel);
• Solenoid relay with drive plug;
• Lids;

All elements are assembled into a single structure and secured with coupling bolts.

The stator due to the passage of electrical energy through its windings, ensures the emergence of an electromagnetic field. The second magnetic field is created by the armature winding. Electric current is supplied to it through graphite brushes to the commutator, to the plates of which the ends of the armature winding are soldered. The magnetic fields generated around the windings lead to the rotational movement of the armature.

On one side of the armature shaft there are splines on which a bendix is ​​mounted, consisting of a gear and an overrunning clutch. Bendix has the ability to move along the shaft, and due to the spline connection, rotation is transmitted to it.

Symptoms of failure

To check the functionality of the generator, a test lamp is included in its connection diagram. If the device is working properly, the control lights up before the engine starts, indicating that the circuit is in working condition, and after the power unit starts, the light should go out.

It is by the indicator lamp, as well as a number of indirect signs, that a generator malfunction can be identified:

• The signal does not light up when the ignition is turned on, while the other measuring instruments are working. Such a problem may indicate a malfunction of the light bulb itself or an open circuit in its power supply;
• It does not light up and other devices do not work. This may indicate a blown fuse, an open circuit in the instrument panel, or a faulty lock or ignition relay;
• The light glows when the engine is running. This may occur due to breakdown of rectifier diodes, regulator malfunction, short circuit or breakage of stator windings, weak drive tension;
• The lamp works normally, but the Oka generator does not charge (the battery is often discharged). This problem can arise as a result of broken contacts in the wiring suitable for the device, a malfunction of the regulator, a malfunction of the rectifier, broken commutator wires, wear of brushes or slip rings;
• The lamp works fine, but the battery is being recharged (it often boils). Here the reason should be sought in the voltage regulator.

The control lamp allows you to identify mainly electrical faults. As for mechanical breakdowns, they manifest themselves in the form of extraneous noise when the engine is running - hum, squealing, whistling. Often such symptoms are caused by loosening the drive tension. But if adjusting the belt does not eliminate the noise, then you should check the condition of the bearings.

Separation by purpose

By purpose, the equipment is divided into:

• Power supplies;
• Protective means;
• Controls;
• Instrumentation;
• Actuators;

Some circuit components have dual purposes. These include relays, which are both control elements and protective devices.

Power supplies

Power sources include the battery and generator. The battery powers the electricity. devices and ensures their operation when the power unit is turned off. After starting the engine, the on-board network is powered from the generator, which also ensures that the battery is recharged.

Protective components

Protective means prevent burnout of electrical appliances and electrical circuits during short circuits. The main protective elements are fuses. For convenience, all protective elements are collected in one place - the fuse box, which in Oka is located under the front panel on the driver’s side.

Controls

Control elements include all components responsible for turning on, switching and turning off electrical appliances. This category combines the ignition switch, all kinds of switches and switches. Most of these elements are located within direct reach of the driver - on the front panel, steering column. But there are switches that the driver acts on through certain components - brake light switches, a sensor for turning on the choke warning light, etc.

Rain sensor DDA-07

The rain sensor is designed to improve comfort, reduce driver fatigue, increase safety, and increase the service life of windshield wipers and blades when driving in rain or wet road conditions. Suitable for domestic cars - Niva, Classic, Oka.

Rain sensor 722.3777-05 (replacement for DDA-07) replaces the windshield wiper relay for VAZ 2121 / 2131 Niva 4x4, VAZ - 2101-2107, 1111 Oka. The device also has a function for adjusting the pause of the wiper swings in the first position of the wiper lever.

List of cars with which this rain sensor works:

VAZ / Lada: -2101; -2102; -2103; -2104; -2105; -2106; -2107; -2121 / 2131 Niva 4×4; -1111 "Oka".

More details about the applicability of the sensor can be found here.

For models VAZ-2108, VAZ-2109, VAZ-2110, VAZ-2111, VAZ-2112, IZH-2126 (old fuse box), AZLK 2141 “Moskvich”, Chevrolet Niva, “UAZ-Patriot”, UAZ-3160 is used relay DDA-15.

For models VAZ-2108, VAZ-2109, IZH-2126 (new fuse block), VAZ-2113, VAZ-2114, VAZ-2115, Kalina, Priora, and some foreign cars, the DDA-25 relay is used.

Model DDA-35 is used on cars with a built-in electronic wiper relay (control signal - minus).

The DDA-45 model is used on the Lada Granta Lux car with a built-in electronic windshield wiper relay (control signal - plus) and other cars with a similar connection diagram.

The DDA-55 model is used on cars with both positive and negative connections. It has pause adjustment and other advanced functions. Recommended for foreign cars.

Model DDA-65 is similar to DDA-55, but additionally includes a light sensor.

Principle of operation:

The optical sensor is placed on the windshield of the car inside the passenger compartment, so that it is in the operating area of ​​the windshield wiper blades. The DDA uses an infrared ray to check the condition of the glass itself. Depending on the presence of moisture or dirt, the level of the reflected signal will change. Based on this signal, the electronic unit will turn on the windshield wiper. Thus, as soon as water appears on the glass, the wipers turn on. The sensor takes into account the speed of the car (the higher the speed, the more often the wipers operate), as well as the intensity of the rain itself. In case of such an unpleasant phenomenon, when your car is splashed out of a puddle by another car, the sensor will see such a large volume of water already at a distance of 10 cm and turn on the windshield wiper in advance. At the same time, the driver can at any time independently turn on the wipers and adjust the frequency of sweeps with a standard switch.

Installation is very simple and does not require special skills or tools.

The operation of the DDA is not affected by factors such as glass fogging, the presence of fog, temperature, or time of day.

Suitable for all types of glass (tinted, athermal, isothermal), because The sensor automatically adjusts to the transparency of the glass.

Warranty - 1 year.
