11. An electric equipment


The 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. Schemes of an electric equipment of the car are presented in subsection 11.1.1 and subsection 11.1.2.

During release of cars VAZ-2101 little changes were brought in their scheme. So, in 1977 the lantern 57 lights of a backing with the switch 26 on a transmission, a tank with the gauge 15 levels of a brake liquid was added. Since 1980 the foot washer of a windscreen with the built in switch of a screen wiper and consequently the scheme of inclusion of a screen wiper has changed began to be established.

The majority of chains joins the ignition switch. Are always included (irrespective of position of a key in the ignition switch) feed circuits of sound signals, прикуривателя, a stoplight, plafonds of illumination of salon and a plug receptacle for a portable lamp.

The car electric equipment is protected by fuses (fig. Fuses see), established under the panel of devices on the left side from a steering column. The chain of a charge of the storage battery, a chain of ignition and engine start-up are not protected by safety locks.

Before to replace fused safety lock, it is necessary to find out the reason of its combustion and to eliminate it. At troubleshooting it is recommended to see chains, which are protected by the given safety lock (see the tab. of the Chain protected by fuses).

It is not supposed to establish the self-made or any other safety locks which have been not provided by a design of the car since it can lead to an overheat of wires and to a fire.
