Check of serviceability of functioning of system of a charge
If in work of system of a charge there is a refusal, it is not necessary to believe automatically that its reason is generator failure. First of all make the following checks:
- Make sure of purity and reliability of fastening on plugs of the battery of tips of its wires.
- Check specific weight of electrolit of the battery. If it is insufficient, make a battery charging (it is inapplicable to batteries of not demanding leaving of type).
- Check a condition of electroconducting and contact plugs of the generator.
- Check a condition and a tension of a driving belt (Head of Control and routine maintenance). In case of need replace it.
- Check durability of a tightening of bolts of fastening of the generator
- Start the engine and check the generator on an izdavaniye to them unusual sounds (squeal or a scratch will indicate bearing failure).

- By means of the voltmeter check tension of the battery at the switched-off engine. It should make about 12 Century.
|
|
- For measurement of tension of the battery connect the voltmeter to its plugs - for measurement of tension of a charge start the engine.
|
- Start the engine and repeat check. Now tension should rise to value of 14-15 Century.
- If the measured values of tension are lower or above stipulated, make check of serviceability of a regulator of tension in dealer office or a car-care center workshop. The tension regulator on these models is a part of the Module of management (RSM) and is not subject to removal and control.
- In view of need of application for carrying out diagnostics and service of the generator of the special tool, originators of this Management recommend in case of an exit it out of operation to drive away the car for check and repair in dealer office or a car-care center workshop. The amateur mechanic should will be limited to performance of quality check and reliability of fastening of contact plugs of electroconducting, a condition of the generator and its replacement in case of need.
- Some models are equipped with the ampermeter established in the dashboard, allowing to define in what condition the battery (a charging or a discharge, i.e. whether there is a current to the battery or from it) stays. At the included electric equipment and the engine of the shooter of the device working at single turns can fix a condition of a discharge of the battery. At operation of the engine on turns of fast idling or at car movement the ampermeter should show a battery charging (the arrow is on the charging party of a scale of the indicator in case the battery is charged or to move towards the charging party of a scale if the battery was "sat down").
- The voltmeter showing tension of the battery at turn of the ignition key in the situation ON before start of the engine and target tension of the generator at the working engine is switched on in an instrument guard of some models also.
- The control lamp of a charge on the dashboard should light up at the key turned in the situation ON and not started engine and immediately to die away after its start.
- If the measuring instrument does not fix a battery charging, when should or a control lamp of the generator (if that is provided) remains included, in system of a charge is available malfunction. Before starting check of a condition of brushes or replacement of the generator check a condition of the battery, contact plugs of electroconducting and a tension of a driving belt of the generator.
