Fig. 4 Single Wire Feed Fusible Link
Fig. 5 Double Wire Feed Fusible Link
To replace a damaged fusible link, Fig. 4, cut it off beyond the splice. Replace with a repair link. When connecting the repair link, strip wire and
use staking-type pliers to crimp the splice securely in two places. For more details on splicing procedures, see Diagnostic Aids/Connector and
Wire Repair. Use Crimp and Seal splices whenever possible.
To replace a damaged fusible link which feeds two harness wires, cut them both off beyond the splice. Use two repair links, one spliced to each
harness wire, Fig. 5.
Typical Electrical Repair
TYPICAL ELECTRICAL REPAIR
An open circuit is an incomplete circuit. Power cannot reach the load or reach ground. If a circuit is open, active components do not energize. A
short circuit is an unwanted connection between one part of the circuit and either ground or another part of the circuit. A short circuit causes a fuse
to blow or a circuit breaker to open.
SHORT CIRCUITS CAUSED BY DAMAGED WIRE INSULATION
^
Locate the damaged wire.
^
Find and correct the cause of the wire insulation damage.
^
For minor damage, tape over the wire. If damage is more extensive, replace the faulty segment of the wire.
Splicing Copper Wire Using Splice Clips
The Splice Clip (included in the GM J 38125-A Terminal Repair Kit) is a general purpose wire repair device. It may not be acceptable for
applications having special requirements such as moisture sealing.
