System of a charge of the battery
On considered cars systems of a charge of 2 types – Bosch and Motorola with rated current 65 are established, 80 and 90 A.Regulyator of tension is mounted on the generator. In system of a charge of Bosch the regulator of tension can be removed from the generator.
The drive of the generator is carried out from a belt with wedge-shaped section. Generators are mounted on the left side of the engine irrespective of model.
Periodic care of system of a charge is reduced to care of the battery and check of a tension of a belt. Periodicity of survey – through каждве 500 km or weekly (that will come earlier).
The control lamp of charge / inclusion of ignition on the dashboard lights up at inclusion of ignition and after start-up of the engine dies away. If the lamp does not die away after engine start-up, in a chain of a charge is faulty. Some cars are equipped with the voltmeter. If the voltmeter shows very high or very low voltage, the chain of a charge needs check (see subsection 188.8.131.52).
1) At connection of the battery with the generator always observe polarity of connection.
2) Before repair of any site of the car by electric welding disconnect wires from the generator and from a battery pole.
3) It is forbidden to start the engine at the connected charger.
4) It is forbidden to disconnect cables from battery or generator poles on the working engine.
