Relay charge at the VAZ-2106 allows to maintain the voltage level at the battery terminals at the same level. The electrical system on any machine is the most complex. Even primitive automobiles “classic” series of vases. But in General, all generators on any cars similar – they consist of the same principle elements. The only differences in the sizes and types of drive.

What is a relay charge

The Entire electrical system is powered by two sources:

  1. Rechargeable battery – when the engine is stopped. It is from the battery provides power to the starter solenoid at the time of starting the engine.
  2. Generator sets – it is designed to supply all consumers while the engine is running. But the primary task – the restoration of battery charge, as after running it loses capacity, and significantly.

The Value of the battery voltage is always the same – you may only decrease, if not will be charge.

VAZ-2106 relay charging

But the alternator can produce voltage in the range of 10-30 Volts. This great range, the electrical system will not be able to cope with such differences. It relay charging VAZ-2106 allows to stabilize the voltage may not allow the surge.

Structure generator

In any car, including in the domestic “six”, the generator consists of the following components:

  1. Stator – this is the fixed part, it is mounted with threaded connections to brackets on the engine block. The stator has a winding (power), consisting of three equal parts – it produced three-phase alternating voltage.
  2. Rotor (anchor) – a rotating element, a coil and two slip rings. Is driven by a belt from the crankshaft.
  3. Front and rear rotor covers are installed. In order that the rotation was as smooth as possible and free, use bearings.
  4. A Pulley for transmitting rotation to the rotor. Installed on it through the dowel is held from turning.
  5. Brushes allow you to send voltage to the coil of the rotating rotor. Relay diagram charging VAZ-2106 also includes a lamp located in the instrument panel. Please note that when combustion occurs the termination voltage supply to the excitation coil.
  6. Semiconductor diodes rectifies three-phase AC voltage. At the exit there is a constant unipolar.

Relay charge at the VAZ-2106, unlike most other cars, is mounted on the body, not in the body of the generator. On many modern cars the voltage regulator and brush Assembly combined in one package.

Why the need For a voltage regulator

The Main function relay battery charging on VAZ-2106 – this is to prevent voltage spikes at the output of the generator set. But to stabilize a large current is not so easy – we need to apply a very massive elements. If low-voltage circuits, you can do the installation of the Zener diode, when the current of 50-60 Amps to make it problematic. But there is a solution – it is possible to stabilize the voltage supplied to the rotary field winding.

VAZ-2106 relay battery charging

If we turn to the school course of physics, we can see that the value of the output voltage of the generator is completely dependent on two parameters-the speed and magnitude of the magnetic field. In other words, it is necessary that the rotational speed of the rotor or the magnetic field was constant. Only in this case, the generator output voltage will not change. But it is impossible without application of special means to maintain the rotor speed at the same level, one thing remains – stabilize the supply voltage of the excitation winding.

Contact controllers

Until now you can find cars that have mechanical voltage regulators. They are extremely imperfect, have a lot of shortcomings, but the owners of such vehicles believe that “the old is always better”. And every three days to climb under the hood to adjust the gap, clean the contacts. But in the case of contact systems, it is convenient to consider the principle of regulators in General. The essence of the processes in the semiconductor and mechanical a bit similar.

how to check the relay charging VAZ-2106

The construction is winding – it magnetizes the metal core. The winding consists of 1300 turns of fine wire. In the diagnosis of such a relay need to know what the resistance of that coil is 17 Ohms.Contacts are made of tungsten. Present in the design of the shunt and the adjusting plate. There are also several springs and resistors, switching the last is mechanical contacts.

Electronic voltage regulators

Manufactured wiring relay charging VAZ-2106 to the excitation winding of the generator. And regardless of electronic or mechanical system is used, assigning her one – to maintain the voltage level of 13.6 Volts. Electronic device more stable mechanical and does not require frequent intervention – they have no mechanical contacts that burn sometimes.

connecting relay charging VAZ-2106

One problem – if you are using relays and brushes, prisoners in one body, we have to change from two nodes. But there are regulators, which are fixed separately from the brush Assembly.

How to check controller

How to check the relay charging VAZ-2106, everyone should know motorist. Main conditions:

  1. Through the device must pass the voltage value which is less than 14 Volts. For diagnosis connect the power from the car battery.
  2. If the voltage is over 14 Volts, it should not pass through the regulator. To check on the scheme to connect elements, and the power supply uses vehicle battery, for example, two AA batteries, connected in series.

The Main symptom that relay charging VAZ-2106 was out of order – the voltage at the battery terminals below the 13.6 Volts.
