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.

That it is necessary to know about electric circuits

Distribution

Further you will find the parts of electroschemes showing always only one certain constructive group of the car. Sense of similar distribution – economy of a place. After all 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

Electroschemes are divided into a set of the chains numbered in the bottom of the scheme. Thus, on the basis of the explanation to the electroscheme 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 speaks about where the wire is connected. Example: B15 means that this wire should be looked for in the multicontact plug on connection In 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 electroschemes of color of wires are given in the form of reductions. Reductions designate: sn – blue; to – brown; – yellow; з – the green; sr – gray; l – lilac; kr – red; h – black; – white.

For what models?

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

In addition electroschemes of other engines which if necessary should be integrated into the mentioned full electroscheme mentally are in summary provided.

In summary electroschemes 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 it is respectively inserted on one multicontact plug 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 electroschemes in the bottom of a 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.
