System of start - 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 installed on it, the blocking relay, the rechargeable battery, the lock of ignition and a connecting electrical wiring.The chain of a starter switched on the blocking relay which at turn of the ignition key in situation START carries out giving of power supply from the battery on a chain of management of start on the traction relay of a starter. The traction relay makes switching of power supply of the battery directly on a starter electric motor. The motor begins to rotate, at the same time turning for a gear wreath of a flywheel / a driving disk a bent shaft of the engine. The blocking relay is placed in the assembly block located in a motive compartment of the car (see the Head Onboard electric equipment). Assembly of a starter with the traction relay is fixed on a transmission dome. On models with AT the chain of management of functioning of a starter switched on the sensor switch of permission of start preventing a possibility of start of the engine in provisions of transmission, excellent from "Р" and "N". On models with RKPP start of the engine becomes possible only at the squeezed-out coupling that is controlled by the sensor switch of disconnection of a chain of a starter. When performing 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 an electric motor of the last as a result of an overheat. Never use a starter continuously further of 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 by conducting ignition; 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 input of the audio system in action! |
