Charge system - the general information and precautionary measures

The charge lamp/indicator, the storage battery, protective fusible insert and electroconducting connecting listed components belong to number of components of system of a charge the generator of an alternating current established on its back wall a regulator of tension, control. The system of a charge provides giving of an electric food to ignition system, lighting and alarm devices, a radio receiver and other consumers of the electric power. The generator is put in action by a belt drive from a pulley of a cranked shaft and is established 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. Head Onboard electric equipment).

Problem of a regulator of tension is restriction of tension developed by the generator in the set limits. The regulator prevents overloads of contours and the other unpleasant phenomena connected with power surges. All models are equipped with the built-in regulator of tension, in default which all generating assembly is subject to replacement.

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, the battery, connecting electroconducting and its terminal connections (see. Head of Control and routine maintenance).

The control lamp of a charge built in in an instrument guard quickly joins at ignition key turn in the situation START and should go out right after implementation of start of the engine. Refusal of a lamp of switching off testifies to malfunctions in charge system. On some models in an instrument guard the voltmeter allowing the driver in due time to trace deviations of onboard tension from norm is in addition established. At an exit of indications of the voltmeter out of limits of an admissible range it is necessary to make check of system of a charge (see. Section Check of a condition of system of a charge).

The fusible insert represents the short piece of the wire placed in isolation which has been built in in the main plait of electroconducting of an impellent compartment. The total section of a vein of the conductor of an insert several times is less than at chain electroconducting in which it is included that guarantees reliable protection of the last against an overload.

When joining terminal connections of electric chains equipped with the generator of an alternating current of cars it is necessary to observe special precautionary measures:

a) At connection of electroconducting of the battery to the generator at all do not allow polarity violation;
b) Before applying at body repair electroarc welding disconnect electroconducting from plugs of the generator and the storage battery;
c) At all do not make engine start at the charger connected to the battery;
d) Always, before making a battery charging from the external power supply, disconnect from it both wires (at first negative);
e) Try not to allow hits of hands, hair and free parts of clothes in contact to a rotating driving belt of the generator during checks made at the working engine;
f) Remember that the generator is connected directly to the battery both its overloads and short circuits are capable to cause ignition of electroconducting and to be at the bottom of a fire;
g) Before starting steam cleaning of an impellent compartment wrap the generator in a plastic bag which then should be fixed reliably rubber bandages.
