10.1. Features of a design

On the car apply an electric equipment of a direct current in rated voltage 12 V.Elektrooborudovanie of the car it 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. A food of consumers is carried out from the storage battery (at the idle engine) and the generator (at the working engine).

Schemes of an electric equipment of the car are resulted in the end of the book.

    

PREVENTIONS Any works with a car electric equipment spend 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 is can cause short circuit in electric equipment chains. It is forbidden to disconnect the storage battery on the working engine, infringement of this rule becomes the reason of failure of a regulator of pressure and elements of the electronic equipment of the car. In order to avoid failure of diodes выпрямительного the generator block it is forbidden to check them мегомметром or the control lamp fed with pressure more 12 In, and to check such devices of a chain of an electric equipment on the car without a detachment of wires from the generator. To check the raised pressure resistance of isolation of a winding статора the generator 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, and also колодки with wires from the electronic block of engine management. Do not concern elements of system of ignition and high-voltage wires on the working engine. Do not lay a low voltage wire in one plait with high-voltage wires. 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 charger devices disconnect wires from battery plugs.
