12.11. Schemes of electric connections

In view of limitation of a place to include in the present Management of the scheme of electric connections of systems of an electric equipment of all considered models it is not obviously possible. For this reason the most typical schemes allowing in the maximum degree in detail to understand basically of action of the basic systems of an electric equipment and onboard consumers of the electric power are more low resulted only.

Before to start diagnostics of refusal any of contours, check up a condition of safety locks protecting it and chain breakers (if the last are provided). Make sure of completeness of a charge of the battery and check up quality of contact connections of wires going from its plugs (Routine maintenance see the Head).

By search of refusal of a concrete contour first of all also check quality of contact connections of its electroconducting. At рассоединении electric sockets try to pull only for their cases, and at all for a plait of wires.
