Address an illustration and the schematic diagram of electric equipment of a tempostat.
The schemes of electric connections given below are made by the schematic principle when components of each contour communicate among themselves on the shortest way without a form of laying of an electrical wiring around the components and plaits located on the way of its following.
On the Audi A3 cars the single-wire scheme of turning on of devices of electric equipment is applied. To plus of power supplies consumers unite a wire, and to 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 the mass of minus of power supplies reduces electrochemical corrosion of metal details of a body. In certain cases direct connection of the electric consumer with weight is not enough, and the consumer unites to weight an additional wire of usually brown color.
Supply voltage is brought to most of consumers via the ignition switch. Power-supply circuits of those knots of electric equipment which work can be required in any circumstances are always connected to the rechargeable battery, irrespective of the provision of a key in the ignition lock.
For connection of wires electric sockets with flat contacts are used.
For normal food of consumers the electric chain has to be closed, otherwise at it there will be electric current, for example, if to the electric motor of a screen wiper positive tension moves, it will not work until its electric chain is not 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 the mass of the car is carried out or directly via the case of the consumer of the electric power or an additional wire.
Contact 30
At this contact there is always positive tension of the accumulator. The wires connected to this contact have color, red or red with a strip.
Contact 31
The contact connects to the mass of the car a wire of brown color.
Contact 15
On this contact positive tension after inclusion of ignition moves. The wires connected to this contact have color, green or green with a strip.
Contact of X
On contact tension after inclusion of ignition moves, however at inclusion of a starter tension is disconnected. It gives the chance at start of the engine to disconnect consumers of the electric power, unnecessary at this moment. High beam headlamps receive food also from this contact therefore at the turned-on driving beam and switching off of ignition there is an automatic switching to marker lights.
Colors of wires are designated by Latin letters.
If in designation of color of a wire there are several letters divided by a sign/, then the left group of letters points to primary color of a wire, and right – to color of a strip.
