7.13. System of a charge - the general information and precautionary measuresThe generator of alternating current with the built-in regulator of tension, the control lamp / indicator of a charge, the rechargeable battery, protective fusible inserts and the electrical wiring connecting the listed components are among components of system of a charge. The system of a charge provides giving of electric food to system of ignition, lighting and alarm fixtures, the radio receiver and other onboard consumers of the electric power. The generator is put in action by the belt drive from a pulley of a bent shaft and is installed in a forward part of the engine. Additional information on electric connections of components of system of a charge can be gathered from schemes of electric connections (see the Head Onboard electric equipment).
Problem of the regulator of tension is restriction of tension developed by the generator in the set limits. The regulator prevents the overloads of contours and the other unpleasant phenomena connected with power surges.
The system of a charge does not need regular service. Nevertheless, it is necessary to check periodically a condition of a driving belt of the generator, battery, a connecting electrical wiring and its terminal connections (see the Head Nastroyki and routine maintenance).
The control lamp of a charge which is built in in an instrument guard quickly joins at turn of the ignition key in position of ON and has to go out right after implementation of start of the engine. The refusal of a lamp of switching off testifies to malfunctions in system of a charge. On some models in an instrument guard the voltmeter allowing the driver to trace in due time deviations of onboard tension from norm in addition is installed. At a release of indications of the voltmeter out of limits of admissible range it is necessary to make check of system of a charge.
When joining terminal connections of electric chains of the cars equipped with the generator of alternating current it is necessary to observe special precautionary measures:
a) At connection of an electrical wiring of the battery do not allow polarity violation to the generator at all;
b) At start of the engine from an auxiliary source you watch correctness of polarity of connection of wires (see the Head Nastroyki and routine maintenance);
c) Before applying arc welding at body repair disconnect an electrical wiring from plugs of the generator and the rechargeable battery;
d) You do not make start of the engine at the charger connected to the battery at all;
e) Always, before making battery charging from the external power supply, disconnect from it both wires (at first negative);
f) Try not to allow hits of hands, hair and free parts of clothes in contact with the rotating driving belt of the generator during made at the working engine of checks;
g) Remember that the generator is connected directly to the battery both its overloads and short circuits are capable to cause ignition of an electrical wiring and to be a cause of the fire;
h) Before starting steam cleaning of a motive compartment wrap the generator in a plastic bag which then should be fixed by rubber bandages reliably.
