12.11. Schemes of electric connections

In view of limitation of a place to include in the real Management of the scheme of electric connections of systems of electric equipment of all considered models it is not obviously possible. For this reason only the most typical schemes allowing in the maximum degree in detail to understand in principle of action of the main systems of electric equipment and onboard consumers of the electric power below are provided.

Before starting diagnostics of refusal any of contours, check 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 quality of contact connections of wires going from its plugs (see. Head Routine maintenance).

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