External displays of malfunctions of system of an electrical supply the following:

- There are no signs of gymnastics АБ;

АБ it is discharged while in service, but signs of infringement of work of the generator are not present;

АБ it is recharged;

- The generator at work publishes strong noise;

- The control lamp of discharge АБ does not light up at ignition inclusion.

If there are no signs of gymnastics АБ the reasons can be the following:

- перегорание a safety lock in a chain of excitation of the generator;

- Easing or damages приводного поликлинового a generator belt;

- Breakage or short circuit in wires;

- Malfunctions of a regulator of pressure;

- Malfunction of the voltmeter or chain of a control lamp of the category.

If АБ it is discharged while in service, but signs of infringement of work of the generator are not present, the reasons can be the following:

- Wrong actions at starter inclusion;

- The energy over-expenditure;

- Easing of contact connections;

- The insufficient size of pressure developed by the generator (because of a faulty regulator of pressure or a weak tension приводного a belt);

If АБ it is recharged, the reasons can be the following:

- The pressure regulator is faulty;

- Short circuit of a conclusion of a winding of excitation of the generator on "weight".

If the generator at work publishes strong noise the reason of it can be:

- Breakage of one of windings статора;

- Malfunction выпрямительного the block;

- Easing of a nut of fastening of a pulley;

- Pollution of contact rings and brushes;

- Absence of greasing in bearings.

It is independently possible to check up only a tension приводного a belt of the generator and a condition of coal brushes of the generator. All other verifying works should be spent on HUNDRED.
