REPAIR PROCEDURES
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 (see Figure 5).

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 con-
nection 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. (Refer to the
splicing instructions for copper, alumi-
num, or shielded cable for the correct
splicing procedure.)

Step One: Open the Harness
If the harness is taped, remove the tape. To
avoid wire insulation damage, use a sewing
"seam ripper" to cut open the harness (avail-
able from sewing supply stores).
If the harness has a black plastic conduit,
simply pull out the desired wire. Note that alu-
minum wire is enclosed in brown conduit.
Refer to Splicing Aluminum Wire if necessary.
Step Two: Cut the Wire
Begin by cutting as little wire off the har-
ness as possible. You may need the extra
length of wire later if you decide to cut more
wire off to change the location of a splice. You
may have to adjust splice locations to make
certain that each splice is at least 40mm (11/2")
away from other splices, harness branches, or
connectors.
