General information

Before starting diagnostics of refusal any of contours, check a condition of the safety locks protecting it and breakers of a chain (if the last are provided). Make sure of completeness of charging of the battery and check quality of contact connections of the wires connected to its polar plugs (see the Head the Current leaving and service).

By search of refusal of a concrete contour first of all also check quality of contact connections of its electrical wiring. At a rassoyedineniye of electric sockets try to pull only for their cases, and not for a plait of wires at all.
