Address to an illustration and the schematic diagram of electric equipment темпостата.

Given below the scheme of electric connections are made by a schematic principle when components of each contour communicate among themselves on the shortest way without a form of laying of electroconducting round located on a way of its following of components and plaits.

On Audi A3 cars the single-wire scheme of turning on of devices of electric equipment is applied. With plus of power supplies consumers incorporate a wire, and to a minus – through a body of the car or on weight. Such method allows to reduce number of wires and to simplify their installation. Connection with mass of a minus of power supplies reduces electrochemical corrosion of metal details of a body. In certain cases it is not enough direct connection of the electric consumer with weight, and the consumer incorporates to weight an additional wire of usually brown color.

The supply voltage is brought to the majority of consumers via the ignition switch. Power-supply circuits of those knots of the electric equipment which work can be demanded in any circumstances, are always connected to the storage battery, irrespective of the provision of a key in the ignition lock.

For connection of wires electric sockets with flat contacts are used.

For a normal food of consumers the electric chain should be closed, otherwise at it there will be an electric current, for example, if to the electric motor of a screen wiper positive tension moves, it will not work until its electric chain will not be connected to weight. In an electric chain switches, the relay, safety locks, measuring devices, electric motors and other consumers of the electric power can be connected. For the correct connection of consumers of the electric power contacts of electric sockets have the corresponding markings. Connection with mass of the car is carried out or is direct via the case of the consumer of the electric power or an additional wire.

Contact 30

On this contact always there is a positive tension of the accumulator. The wires connected to this contact, have red or red color with a strip.

Contact 31

Contact incorporates to mass of the car a wire of brown color.

Contact 15

On this contact positive tension after ignition inclusion moves. The wires connected to this contact, have green or green color with a strip.

Contact X

On contact tension after ignition inclusion moves, however at starter inclusion tension is disconnected. It gives the chance to disconnect at start of the engine consumers of the electric power unnecessary at this moment. Headlights of a driving beam receive a food also from this contact therefore at the included driving beam and switching off of ignition there is an automatic switching on marker lights.

Colors of wires are designated by Latin letters.

If in designation of color of a wire there are some letters divided by a sign/, the left group of letters indicates primary color of a wire, and right – on color of a strip.

bl	The dark blue
br	The brown
el	The cream
ge	The yellow
gn	The green
gr	The gray
hbl	The blue
hgn	The salad
li	The lilac
nf	The transparent
og	The orange
rbr	The claret
ro, rt	The red
rs	The pink
sw	The black
vi	The violet
ws	The white

On the scheme all consumers of a current and switches are represented in neutral situation.
