Charge system - the general information and safety measures

The structure of system of a charge includes the generator, a control lamp of a charge, the battery, the management module (РСМ), a fusible safety insert and connecting wires between components. The charge system provides with power supplies ignition system, lighting devices, a radio tape recorder and an other electric equipment of the car. Generator rotation is carried out established in a forward part of the engine приводным by a belt.

Subsystem in generator management in target parametres in structure. РСМ provides updating of level of pressure developed by the generator according to concrete requirements (operating conditions) of the engine. Thereby loading decrease on the engine is carried out at change of parametres of movement, speed of the car, cooler and condition temperatures (incl. / off) electric equipments (air conditioner, lighting devices, a radio tape recorder, etc.).

Problem of a regulator of pressure is restriction of pressure developed by the generator in certain limits that gives the chance to avoid caused by jumps of pressure of overloads of contours.

The charge system usually does not demand regular service. However, it is not necessary to forget about necessity of check of a condition drive a belt of the generator, the battery and electric contacts according to the schedule of routine maintenance of the car (the Head of Adjustment and routine maintenance).

In default the generator it is necessary to replace with its uniform block. The same concerns also the block of a regulator of pressure if it is placed in РСМ.

The control lamp on an instrument guard should light up at ignition key turn in position ON, and after realisation of start of the engine immediately to die away. If the lamp remains lighted, in charge system there is a malfunction (Section Check of serviceability of functioning of system of a charge). Some of cars are equipped also by the voltmeter. If voltmeter indications are excessively high, check up a condition of system of a charge (Section Check of serviceability of functioning of system of a charge).

At check of a condition of contacts of electroconducting of contours of system of a charge on the cars equipped with the generator of an alternating current it is necessary to be careful:

  • At connection to the generator of wires from the battery watch for polarity observance.
  • Before applying to repair work electroarc welding disconnect wires from the generator and the battery.
  • At all do not start the engine during battery gymnastics.
  • Before the beginning of gymnastics of the battery always disconnect from it wires.
  • Generator rotation is carried out приводным by a belt hit under which hands, hair and clothes at the working engine is fraught with reception of serious traumas - be attentive.
  • Whereas the generator is connected directly to the battery, its overload or short circuit can become the reason of occurrence of an electric arch and lead to a fire.
  • Before the beginning of carrying out of steam cleaning of the engine wrap the generator in a polyethylene package, которы1 fix rubber bandages.
  • At all do not disconnect the battery at the working engine.
