Electric schemes

Electric schemes separate electric chains of system the friend near to the friend so functional interdependence becomes more obvious and clear. However to the car under these images it is impossible to understand passage of wires.

That it is necessary to know about electric schemes


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 as the car with the engine with capacity of 66 kw, and the car with the engine capacity of 128 kw. So choose to yourself that site with which you are going to be engaged at present.


Electroschemes are divided into set of the chains numbered in the bottom of the scheme. Thus, on the basis of the explanatory to the electroscheme it is possible to find separate elements easily. The bottom line designates "weight" of the car (that is body metal) through which the electric chain becomes isolated. The grey field on top shows to edge of schemes the central switchboard. The designation штекерных contacts speaks about where the wire is connected. An example: В15 means that it is necessary to search for this wire in the multicontact tip on connection In the central switchboard.

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

Colours of wires

In electroschemes of colour of wires are given in the form of reductions. Reductions designate: сн – dark blue; to – brown; – yellow; з – green; ср – grey; l – lilac; кр – red; ч – black; – white.

For what models?

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

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

In summary electroschemes of additional elements of equipment are resulted in it, for example, antifog headlights.

The image shows a payment of the central switchboard from below. It is divided into cells штекерных contacts into which it is accordingly inserted on one multicontact tip and which are designated by letters of the Latin alphabet. Designations of plugs are in addition specified. Designations you will find both these on electroschemes in the bottom of a grey field which should represent the central switchboard. Under this data it is necessary to search for a cable in the central switchboard.
