Check all external lighting and a sound signal.
Visually check all available electric sockets, plaits of wires and a bracket of fastening of plaits of wires.
If any separate bulb of external lighting, probably does not burn, the bulb fused and it is necessary to replace it. If both bulbs of stoplights, probably do not burn, the switch of stoplights failed.
If some bulbs at the same time do not burn, it is possible, there is a damage to an electric power-supply circuit of bulbs or fused the fuse.
For safety lock replacement, having pulled, take a safety lock from a nest and establish the new safety lock calculated on the same current. If the safety lock repeatedly fuses, find out and eliminate the reason of its peregoraniye.
