One type of fuse link is a short length of special, Hypalon (high temperature) insulated wire, integral with the engine compartment wiring harness and should not be confused with standard wire. It is several wire gauges smaller than the circuit which it protects. Under no circumstances should a fuse link replacement repair be made using a length of standard wire cut from bulk stock or from another wiring harness.
The second type of fuse link is similar looking to a large fuse in the fuse block. This type of fuse link can be inspected through the clear top.
The third type of fuse link is a piece of wire with a fuse holder in the center of it, which usually attaches to the battery or starter.
Fusible links are used to prevent major wire harness damage in the event of a short circuit or an overload condition in the wiring circuits that are normally not fused, due to carrying high amperage loads or because of their locations within the wiring harness. Each fusible link is of a fixed value for a specific electrical load and should a fusible link fail, the cause of the failure must be determined and repaired prior to installing a new fusible link of the same value.
The fusible link can be located near the battery and or starter motor and also may be incorporated into the fuse block.
