Repair Sharan/Sharan Volkswagen>> Electric equipment>> Generator>> Generator check
External manifestations of malfunctions of system of power supply following:
- there are no signs of a charging of AB;
AB is discharged in use, but signs of violation of operation of the generator are not present;
AB is recharged;
- the generator at work publishes strong noise;
- the control lamp of a discharge of AB does not light up at ignition inclusion.
If there are no signs of a charging of AB, the reasons can be the following:
- a safety lock peregoraniye in a chain of excitement of the generator;
- easing or damages of a driving poliklinovy belt of the generator;
- break or short circuit in wires;
- malfunctions of a regulator of tension;
- malfunction of the voltmeter or chain of a control lamp of the category.
If AB is discharged in use, but signs of violation of operation of the generator are not present, the reasons can be the following:
- the wrong actions at starter inclusion;
- energy overexpenditure;
- weakening of contact connections;
- the insufficient size of tension developed by the generator (because of a faulty regulator of tension or a weak tension of a driving belt);
If AB is recharged, the reasons can be the following:
- the tension regulator is faulty;
- short circuit of a conclusion of a winding of excitement of the generator on "weight".
If the generator at work publishes strong noise, the reason of it can be:
- break of one of stator windings;
- malfunction of the vypryamitelny block;
- weakening of a nut of fastening of a pulley;
- pollution of contact rings and brushes;
- lack of greasing in bearings.
It is independently possible to check only a tension of a driving belt of the generator and a condition of coal brushes of the generator. All other verifying works should be carried out on HUNDRED.
