General information

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 charging of the battery and check quality of contact connections of the wires connected to its polar plugs (see. Head Current leaving and service).

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.
