Repair and operation of the car

Most of consumers of the electric power unite to "weight" wires of brown color. For the correct connection of devices of electric equipment their contacts are numbered.

For convenience of use all electric chains on electroschemes are located vertically and numbered.

From above on schemes the block of safety locks and the relay limited from below to the horizontal line is represented. Thin lines over it are internal connections in the block.

Horizontal lines in the block at numbers 30, 15, H and 31 – internal connections of the block with power supplies and "weight". The chain 30 constantly is energized the battery, the chain 15 – only at the included ignition and receives food via the ignition lock. The chain of X is energized also at the included ignition, but at inclusion of a starter it is disconnected. The chain 31 is connected to "weight".

From below on schemes there passes the horizontal line which shows connection with "weight".

The figures in circles standing near crossing of vertical chains with the horizontal weights line indicate an arrangement of points of "weight" on a body.

The figure in a white square at the end of a vertical chain shows, in what chain it is necessary to watch continuation of this wire. Colors of wires on schemes correspond to flowers of wires on the car. The figure on each wire means the area of section of a conducting vein of a wire in square millimeters.

The figure in a black square designates number of the relay in the block of safety locks and the relay, the letter in a circle standing near a wire – one-piece connection of wires.
Internal connections (thin lines) – such connections do not represent wires, however on them there is an electric current. They give the chance to track ways of course of current in electric equipment.

The clip 15 – at the included ignition on it is available accumulator tension.

Position number of the relay – designates the relay, designates number of the relay on the additional panel of the relay.

Section of a wire is given in ^mm2.

Designation of an element – allows to find the name of the element presented by a graphic symbol in the list.

Color of a wire – corresponds to color of a wire in the car.

Designations of kotnakt – on the relay, a control unit and on a payment or the additional panel of the relay.

Alphanumeric designation in places of connections – defines the provision of wires in sockets (M30az).

Figures in small squares – designate interruption of a chain and set number of a current path of continuation of a chain.

Alphanumeric designation – notes demountable connection (T8a/7).
