As it is impossible to include in the management of the scheme of electric equipment of cars of all models and years of release which are described in this management, the most typical schemes which it is necessary to address most often are provided further.

Before diagnostics of any electric chain, check safety locks and automatic switches (if are established) to be convinced that they in good shape. Check accumulator charging, and also that connections of wires of the accumulator were pure and reliable.

When checking wires, check that all connections and sockets of connection were pure, without the broken or badly connected contacts. At a connection socket detachment, do not pull for wires, undertake only the socket case.
