Charge system – the general information and safety measures

Function chart of typical system of a charge

The control lamp/indicator of a charge, the storage battery, protective fusible inserts and electroconducting connecting listed components (address to an illustration above) concern number of components of system of a charge the generator of an alternating current with the built in unattended regulator of pressure. The charge system provides giving of an electric food to ignition system, lighting and alarm devices, an audiosystem and other onboard consumers of the electric power. The generator is put in action by a belt drive from a pulley of a cranked shaft and established in a forward part of the engine. The additional information on electric connections of components of system of a charge can be gathered from schemes of electric connections (the Onboard electric equipment see).

Problem of a regulator of pressure is restriction of pressure developed by the generator in the set limits. The regulator prevents overloads of contours and the other unpleasant phenomena connected with jumps of pressure.

Fusible inserts on considered models replace safety locks, differing from the last большей токопропускной ability. Inserts are placed in the assembly block of the relay located in an impellent compartment (the Onboard electric equipment see).

The charge system does not require regular service. Nevertheless, it is necessary to check periodically a condition приводного a belt of the generator, the battery, connecting electroconducting and it клеммных connections (see the Head of Adjustment and car routine maintenance).

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

At joining клеммных connections of electric chains equipped with the generator of an alternating current of cars it is necessary to observe special safety measures:

   a. At connection of electroconducting of the battery to the generator at all do not suppose polarity infringement;
   b. Before to apply at кузовном repair electroarc welding disconnect electroconducting from plugs of the generator and the storage battery;
   c. At all do not make engine start at connected to the battery зарядном the device;
   d. Always, before to make gymnastics of the battery from the external power supply, disconnect from it both wires (at first negative);
   e. Try not to suppose hit of hands, hair and free parts of clothes in contact with rotating приводным a 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 to start steam cleaning of an impellent compartment wrap the generator in a polyethylene package which then should be fixed reliably rubber bandages.
