System of a charge – the general information and precautionary measures

General information

The generator of alternating current which is built in it tension regulator, the charge level indicator, the battery, a protective fusible insert and the electrical wiring connecting the listed components is among components of system of a charge. The system of a charge provides giving of electric food to system of ignition, lighting and alarm devices, the 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 installed in 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).

The electronic control unit (ECU), depending on the current values of input parameters (engine turns, speed of the movement of the car, temperature of cooling liquid, number of the included consumers of the electric power and temperature of the soaked-up air), gives out command for adjustment of size of tension developed by the generator. The main task of system is minimization of load of the vehicle engine.

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, an electrical wiring and its terminal connections (see the Head Routine maintenance).

The control lamp which is built in in an instrument guard quickly joins at turn of the ignition key in the situation ON. Right after implementation of start of the engine the lamp has to go out. 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 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.

The fusible insert represents the short piece of the wire placed in isolation which is built in in the main braid of an electrical wiring of a motive compartment. Total section of a vein of the conductor of an insert several times is less than at an electrical wiring of a chain in which it is included that guarantees reliable protection of the last against an overload.

Precautionary measures

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) Before applying arc welding at body repair disconnect an electrical wiring from plugs of the generator and the battery;
   c) Do not make start of the engine at the charger connected to the battery at all;
   d) Always, before making battery charging from the external power supply, disconnect from it wires (at first negative);
   e) Try not to allow hit 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;
   f) As the generator is connected directly to the battery, its overloads and short circuits are capable to cause ignition of an electrical wiring and to be a cause of the fire;
   g) Before starting steam cleaning of a motive compartment wrap the generator in a plastic bag which then should be fixed reliably rubber bandages.
