Start system - the general information and precautionary measures

The system provides an engine provorachivaniye for the purpose of implementation of its start. The main components of system are a starter with the traction relay established on it, the blocking relay, the storage battery, the lock of ignition and connecting electroconducting.

The blocking relay which at ignition key turn in the situation START carries out power supply giving from the battery on a chain of management of start on the traction relay of a starter is switched on in a chain of a starter. The traction 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. The blocking relay is placed in the assembly block located in an impellent compartment of the car (see. Head Onboard electric equipment). Starter assembly with the traction relay is fixed on a transmission dome.

On models from AT in a chain of management functioning of a starter switched on the sensor switch of permission of the start, preventing possibility of start of the engine in provisions of transmission, distinct from "R" and “N”. On models from RKPP start of the engine becomes possible only at the squeezed-out coupling that is supervised by the sensor switch of disconnection of a chain of a starter.

At performance of any works on service of components of system of start it is necessary to observe the following special precautionary measures:

a) Remember that excessively long provorachivaniye of the engine a starter can lead to serious damages of the electromotor of the last as a result of an overheat. Never use a starter continuously further 15 seconds then it should allow to cool down within one-two minutes;
b) Do not forget that the starter is connected directly to the battery that at careless handling, as a result of overloads and short circuits, does probable the possibility of a dugoobrazovaniye fraught in turn with ignition of conducting;
c) Performing any works with components of system of start, without fail disconnect a negative wire from the battery, - remember that if the stereosystem established on the car is equipped with a security code before disconnecting the battery it is necessary to make sure of knowledge of the correct combination for audiosystem input in action!
