9.1. Features of a design

On the car the electric equipment of a direct current with rated voltage is applied 12 Century

The car electric equipment is executed under the single-wire scheme – negative conclusions of sources and electric power consumers are connected to "weight" which carries out function of the second wire. In turn, "the weight" role carries out a car body.

The majority of chains joins the ignition switch. Are always included (irrespective of position of a key in the ignition switch): a control lamp of automobile anticreeping system, blocking of locks of doors, the alarm system a headlight of headlights, braking signals, external illumination, plafonds of illumination of salon and individual illumination, the alarm system, a sound signal and подкапотная a lamp.

In tab. 9.1 value of each safety lock is given, but on concrete model of the car there can be no some chains specified in the table.

PREVENTIONS Any works with a car electric equipment make only at the disconnected storage battery. To disconnect or connect the storage battery it is possible only at the switched off ignition. At check of chains of an electric equipment it is forbidden to close on "weight" of a wire (to check serviceability of chains «on a spark») as it can lead to failure of elements of an electric equipment. It is forbidden to apply the safety locks not provided by a design of the car or calculated on больший a current, and also to use instead of safety locks a wire. At replacement of safety locks it is forbidden to apply screw-drivers and the metal tool as it can lead to short circuit in electric equipment chains. It is forbidden to disconnect the storage battery on the working engine as it will lead to failure of a regulator of pressure and elements of the electronic equipment of the car. In order to avoid failure of diodes выпрямительного the block it is forbidden to check them мегомметром or the control lamp fed with pressure more 12 In, and also to check such devices of a chain of an electric equipment on the car without a detachment of wires from the generator. To check resistance of isolation of a winding статора the generator the raised pressure it is necessary on the generator which has been removed from the car, at disconnected from выпрямительного the block winding conclusions статора. At carrying out of electrowelding works on the car it is necessary to disconnect wires from plugs of the storage battery and the generator. Do not concern elements of system of ignition and high-voltage wires on the working engine. It is forbidden to check working capacity of system of ignition «on a spark» between tips of high-voltage wires and "weight" as it will lead to failure of elements of the electronic equipment. Do not lay a low voltage wire in one plait with the high-voltage. Regularly clear plugs of the storage battery and tips of wires of oxides and a dirt. At additional charge of the storage battery with the help зарядного devices disconnect wires from battery plugs
