General information and precautionary measures
The generator of the alternating current which has been built in it a regulator of tension, control lamp of a charge, the storage battery, protective fusible insert and electroconducting connecting listed components belong to number of components of system of a charge. 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).
The electronic control unit (ECM, depending on the current values of input parameters (engine turns, speed of movement of the car, temperature of cooling liquid, number of the included consumers of the electric power and temperature of soaked-up air), makes adjustment of size of tension developed by the generator. The main task of system is minimization of load of the engine.
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.
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 Routine maintenance).
The control lamp of a charge built in in an instrument guard quickly joins at ignition key turn in the situation ON. Right after implementation of start of the engine the lamp should go out. Refusal of a lamp of switching off testifies to malfunctions in charge system (see. Removal and installation of components of system of preheat). On some models in an instrument guard the voltmeter allowing the driver in 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. Removal and installation of components of system of preheat).
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:
The system provides an engine provorachivaniye for the purpose of its start.
The main components of system are a starter with the traction relay established on it, the storage battery, the lock of ignition and connecting electroconducting.
Starter assembly with the traction relay is fixed from above on the power unit, near a transmission dome.
At ignition key turn in the situation START power supply from the battery on a chain of management of start moves on the traction relay of a starter. The relay makes switching of a food of the battery directly on the starter electromotor. The motor starts to rotate, at the same time turning for a gear wreath of a flywheel / a driving disk a cranked shaft of the engine.
Starter functioning on the models equipped with RKPP, becomes possible only at the squeezed-out pedal of coupling. On models from AT an indispensable condition is transfer of the lever of the selector to the situation "R" or "N".
At performance of any works with components of system of start it is necessary to observe the following special precautionary measures:
