VAZ-2110: voltage regulator: principle of operation, device, diagram and replace

The voltage generated by the motor generator, is not constant and depends on the number of revolutions of the crankshaft. In order to stabilize it, designed a special regulator. About it we will talk in this article on the example of the car VAZ-2110.

Why the need For a voltage regulator

The Regulator is used to maintain the voltage of the machine within the specified limits, regardless of the speed of rotation of the shaft of the generator, load, and temperature. In addition, it provides stable charging of the car battery.

Connection Diagram and working principle

The voltage Regulator on most vehicles, connected to the onboard network in the following diagram.

The Principle of operation of the voltage regulator (PH) is the same as the relay. In other words, he opens and closes the circuit. That is why the device is called the relay-regulator. It is triggered when the change of the preset value of the voltage coming from the generator.

The First regulators had electromagnetic design. Those were the real relay. Modern devices are made on the basis of semiconductors. They are characterized by small dimensions, and in addition, are much more precise and more efficient. Some of them are even equipped with special detectors which allow the driver to monitor their performance.

Voltage Regulator VAZ-2110

PH “dozens” also has solid-state design. It is integrated into the generator, which allows to maintain the required voltage directly at the output device.

Specifications PH VAZ-2110

Relay-voltage regulator generator VAZ-2110 has the following features.

Symptoms PH

The VAZ-2110 voltage regulator breaks down very rarely, but if it happens, signs of malfunction are:

• Failure of the backlight of the control panel.
• Exceeding the voltage level of the battery charge.
• Low voltage battery.

In case of breakage relay-voltage regulator VAZ-2110 probably a blown fuse responsible for the security of the power supply circuit of the instrument panel. If the backlight lamp when the ignition does not light, there is a likelihood that the guilty is RN.

The same can be assumed, and when the pointer of the voltmeter indicates the charging level of the battery deviates from its usual position, i.e. shows more or less voltage. this symptom is most often seen when the relay-voltage regulator generator VAZ-2110 fails. And if in the second case, it could only cause discharge, then it threatens in the first boiling of the electrolyte and destruction of the plates of the battery.

How to test the PH on VAZ-2110, never taking it off

Finding at least one of the following symptoms, do not be lazy to check on your VAZ-2110 voltage regulator. This procedure will not take more than 10 minutes. This will require a voltmeter or multimeter on its mode, as well as the assistant. Procedure check the following:

1. Start the engine and warmed it up to operating temperature.
2. Turning off the motor, hook up one test lead of the voltmeter to terminal "B+" of the generator, and the second – to “mass” devices.
3. Ask the assistant to turn on dipped headlights and press on the accelerator pedal hold the revs at the level of 2000-2500 thousand about./min.
4. Measured the voltage of the device.

The VAZ-2110 voltage regulator must issue a 13.2 and 14.7 V. This is the norm. If the performance of the voltmeter differ from those shown, diagnostic measures should continue.

Check recorded voltage regulator

To verify that the out of order PH that is, not the generator, it should be checked separately. For this you needdisconnect from the primary device. The procedure is as follows:

1. Remove the negative terminal from the battery.
2. Find the attachment point PH to the generator. Unscrew the 2 screws fixing it.
3. Disconnect the yellow wire coming from the regulator to the generator.
4. Dismantle the PH.

To diagnose the device will require a power supply with adjustable output voltage, the bulb (12) with cartridge and a pair of wires. The algorithm is as follows:

1. Collect “kontrolka” from lamps and wires and connect it to the brushes of the regulator.
2. Adjustable voltage on the power supply at 12 V.
3. The output from ‘D+" controller input “plus” from the power supply, but to its “mass” – “minus”.
4. Look at the lamp: it should glow.
5. Increase the voltage on the power supply to 15-16 V. and With proper regulator light should go out. If this has not happened – the PH must be replaced.

Replacement PH

The process of replacing the voltage regulator of particular difficulty is no different. All you need to do – is to buy a new device, test it as described above and install the generator, screwing the two screws. And don't forget to connect the yellow wire!

Three-level voltage regulator VAZ-2110

Now let's back up a bit. Finding fault PH and deciding to replace it, do not rush to buy stock the device. There is a decent alternative – a three-level inverter. How is it different from usual? It allows you to adjust the voltage at the output depending on the temperature, thereby optimizing the load on battery.

The Switch is a toggle switch in these ranges:

• 13.6 In (at least) – for working temperatures above +20^OC;
• 14,2 V (norm) – 0^OTo 20^OC;
• 14,7 V (maximum) – for operation at temperatures below 0^OC.

Three-level voltage regulator VAZ-2110 consists of two parts: the PH and the brush holder. The latter is mounted directly on the generator and connected with the first by using wires. The regulator is equipped with a toggle switch, mounted to the vehicle body in the engine compartment in a convenient location. Set RN can be independently, using the user manual coming with it included.
