Check of system of a charge Remember that generator failure is not a unique possible cause of infringement of serviceability of functioning of system of a charge. At revealing of signs of refusal of system execute following checks:
- Check up a condition and effort of a tension приводного a generator belt, in case of need make its replacement (see the Head of Adjustment and car routine maintenance);
- Check up reliability of a tightening of bolts of fastening of the generator;
- Check up a condition of electroconducting of the generator and it клеммных connections, in case of need remove oxidation products, tighten fixture;
- Check up a condition of corresponding safety locks (the Onboard electric equipment see the Head), - before replacement of the punched safety lock eliminate the overload reason;
- Start the engine and make sure that the generator does not publish any extraneous noise, - whistle or squeal can testify to deterioration of bearings or brushes;
- Check up completeness of level of gymnastics of the storage battery, - remember, that damage of one of банок can lead to increase of a current of consumption;
- Disconnect from the battery both wires (at first negative) and attentively study a condition of polar plugs, - in case of detection of traces of corrosion carefully smooth out plugs, it is desirable with application of special adaptations, track reliability of fixing on plugs of tips of wires.
|
- Check up target pressure of the storage battery at the switched off engine, - the result of measurement should make an order 12 Century
|
- Check up a chain of gymnastics without loading. For this purpose disconnect a wire from plug B of the generator and connect this wire to negative щупу the ampermeter. Positive щупы the ampermeter and the voltmeter connect to generator plug B. Negative щуп the voltmeter connect to weight of the car. Start the engine and, having increased turns with single to 2000 rpm, consider indications of measuring devices and compare them to requirements of Specifications of the Head of System of an electric equipment of the engine.
|
- If pressure above admissible, replace a pressure regulator (on generator L3B) or winding assemblage (on generator SC1).
|
- If pressure of generator L3B below admissible, check up the generator and a pressure regulator. For this purpose at earthed plug F start the engine and check up pressure on plug B. If pressure above admissible, replace a pressure regulator. If pressure below admissible, check up the generator.
|
- Check up a chain of gymnastics without loading. For this purpose at the engine working on 2000 rpm include a headlight of headlights and include the heater fan in a mode «HI». Measure force of a current of the generator and compare it to requirements of Specifications of the Head of System of an electric equipment of the engine. If the measured value below admissible, repair the generator.
|
Ampermeter indications can be below admissible value if the battery is completely charged. |
- At excess by target pressure of the top border of an admissible range it is necessary to make replacement of a regulator of pressure.
- The reason of excessive understating of pressure deterioration of brushes of the generator, easing щеточных springs, regulator refusal, diode failure, winding breakage, and also damage of rings of a collector can be. The condition of brushes and collector rings can be checked up visually, - in the absence of obvious damages the generator should be removed from the car (see Has undressed Removal and generator installation) for more detailed check and regenerative repair/replacement.
