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 following checks:

    Make sure of cleanliness and reliability of fastening on plugs of the battery of tips of its wires. Check up relative density of electrolit of the battery. If it is insufficient, make battery gymnastics (it is inapplicable to batteries of not demanding leaving of type). Check up a condition of electroconducting and contact plugs of the generator. Check up a condition and a tension drive a belt (the Head of Adjustment and routine maintenance). In case of need replace it. Check up durability of a tightening of bolts of fastening of the generator Start the engine and check up the generator on издавание it of unusual sounds (squeal or a scratch will specify in bearing failure).


    By means of the voltmeter check up pressure of the battery at the switched off engine. It should make approximately 12 Century
    For measurement of pressure of the battery connect the voltmeter to its plugs - for measurement of pressure of a charge start the engine.
    Start the engine and repeat check. Now pressure should rise to value 14 - 15 Century If the measured values of pressure more low or above stipulated, make check of serviceability of a regulator of pressure in dealer branch or a car-care centre workshop. The pressure regulator on the given models is a part of the management Module (РСМ) and is not subject to removal and adjustment. In view of necessity of application for carrying out of diagnostics and service of the generator of the special tool, composers of the given Management recommend in case of an exit it out of operation to drive away the car for check and repair in dealer branch or a car-care centre workshop. The Mechanic-fan 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 established in the panel of devices by the ampermeter, allowing to define in what condition the battery (gymnastics 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 marksman of the device working on single turns can fix a condition of a discharge of the battery. At engine work on turns of fast idling or at movement of the car the ampermeter should show battery gymnastics (the arrow is on зарядной to the party of a scale of the indicator in a case if the battery is charged or to move aside зарядной the scale parties if the battery was "sat down"). The voltmeter showing pressure of the battery at turn of the ignition key in position ON before start of the engine and target pressure of the generator at the working engine is included in an instrument guard of some models also. The control lamp of a charge on the panel of devices should light up at the key turned in position ON and not started engine and immediately to die away after its start. If the measuring instrument does not fix battery gymnastics, when should or a control lamp of the generator (if that is provided) remains included, in charge system is available malfunction. Before starting check of a condition of brushes or generator replacement check up a condition of the battery, contact plugs of electroconducting and a tension drive a generator belt.
