Electric circuits - the general information

As inclusion in this manual of the electric circuits corresponding to models of all years of release is impossible, only the most typical of schemes demanding the frequent address to them are collected and presented in this Section.

Before starting diagnostics of malfunctions of electric contours check a condition of safety locks and breakers of a chain (if those are provided) as their burn-out can will be a contour cause of failure. Make sure that the battery is completely charged, and tips of wires are reliably connected to its plugs (The head Nastroyki and routine maintenance).

During check make sure of purity of all contacts, track that plugs were not broken off, and their fastening is weakened. At a rassoyedineniye of electric sockets never pull for wires - always undertake the socket case.

The card of color codes of the wires accepted on cars of this brand is given in the table below.
