Electric circuits

Electric circuits separate electric chains of system the friend near the friend so functional interdependence becomes more obvious and clear. However passing of wires in the car according to these images cannot be understood.

What it is necessary to know about electric circuits

Distribution

Further you will find the parts of electrical circuitries showing always only one certain constructive group of the car. Sense of similar distribution – economy of the place. The area of system of a screen wiper concerns both the car with the 66 kW engine, and the car with the 128 kW engine. So choose to yourself that site with which you are going to be engaged at present.

Construction

Electrical circuitries are divided into a set of the chains numbered in the bottom of the scheme. Thus, on the basis of the explanation to the electrical circuitry it is possible to find separate elements easily. The lower line designates "mass" of the car (that is body metal) through which the electric chain becomes isolated. The gray field at the upper edge of schemes shows the central switchboard. Designation of shtekerny contacts says about where the wire is connected. Example: B15 means that this wire should be looked for in the multicontact plug on connection B of the central switchboard.

If any wire comes to an end in a rectangular frame in which the number is specified – for example, 15 – that you will find continuation of this wire in the called number of an electric chain, in an example it is a chain number 15.

Colors of wires

In electrical circuitries of color of wires are given in the form of reductions. Reductions designate: сн – blue; to – brown; – yellow; з – green; ср – gray; l – lilac; кр – red; h – black; – white.

For what models?

Further you will find the full electrical circuitry of the Audi 80 car of 1992 of release. Electrical circuitries on the engine describe the 4-cylinder engine with system of injection Mono-Motronic and 66 kW.

In addition electrical circuitries of other engines which if necessary should be integrated into the mentioned full electrical circuitry mentally are in conclusion provided.

In conclusion electrical circuitries of additional elements of equipment, for example, of fog lights are provided to it.

The image shows a payment of the central switchboard from below. It is divided into cells of shtekerny contacts into which about one multicontact plug is respectively inserted and which are designated by letters of the Latin alphabet. Designations of plugs are in addition specified. You will find both of these designations on electrical circuitries in the bottom of the gray field which has to represent the central switchboard. According to these data it is necessary to look for a cable in the central switchboard.
