15.18. Safety locks
Safety locks serve to break off a chain, when the current will reach a certain value to protect elements and wires which can be damaged by too strong current. The sharp increase in a current is usually caused by malfunction in a chain, more often short circuit.
Designations of the chains protected by safety locks, are specified on a cover of the block of safety locks.
Before removal of a safety lock switch off the corresponding chain (or ignition), then get a safety lock from contacts. In a safety lock the wire should be visible; if the safety lock fused, the wire will be broken off or melted.
Always use safety locks of the demanded capacity. Never use a safety lock of other capacity and do not replace it with something another.
Do not replace a safety lock more than once, without having eliminated a malfunction source. The current protected by a safety lock, is specified from above on a safety lock: pay attention that safety locks have various colors for simplification of identification. If the safety lock fuses right after replacement, do not replace it again, yet do not establish and do not eliminate a cause of defect. In most cases a cause of defect is the short circuit caused by a low insulation. If the safety lock protects some chains, try to find a chain because of which fuses a safety lock, including each of chains in turn (if it is possible). Always have in the car a set of spare safety locks of various capacity. They should be fixed at the basis of the block of safety locks.
