TAPE AGAIN IF NEEDED
Figure 12 - Proper Second Taping
—Small cylindrical metal splice clips.
—A plastic tube of petroleum jelly.
—Ten 2.0 metric (14 gauge) DK GRN leads:
150mm (6") long with terminals.
—Ten LO metric (16 gauge) BRN leads: 150
mm (6*1 long with terminals.
Use of the special materials in this kit will
help prevent galvanic corrosion. Galvanic cor-
rosion causes increased resistance between the
terminal and wire, or the splice clip and wire, or
both. Increased resistance would affect the
operation of the electrical components in the
repaired circuit.
Step One: Open the Harness
Because the harness has a solid plastic con-
duit, simply cut the conduit open with
diagonal cutters and pull out the desired wire.
Be careful not to damage any of the wires when
cutting open the conduit.
Step T w o : 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 '1
away from the other splices, harness branches,
or connectors.
Step Three: Strip the Insulation
When replacing a wire or lead, use a wire of
the same size as the original wire, or larger.
Look up the metric wire size on the schematic
and select the proper-sized leads from the spe-
cial repair kit. Remember that the wires in this
harness can only be one of two sizes-2.0 metric
or 1.0 metric (14 or 16 gauge).
Use wire strippers of the proper gauge to
strip approximately 6mm (1/4") of insulation
from each wire end.
When stripping the outer jacket from the
aluminum wire core, be careful not to nick or
damage the core. A damaged core will weaken
the assembly at this point.
Step Four: Coating the Splice/Terminal
To prevent corrosion, apply a generous coat-
ing of petroleum jelly to the splice area. If you
are replacing a lead, also thoroughly coat the
terminal crimp area and aluminum core with
petroleum jelly. Both areas are shown in Fig-
ure 13 and identified with the letter
44
A."
Step Five: Crimp the Wires
—Select the proper-sized splice clip (follow
the instructions included in the special
repair kit).
— Place one wire end in each end of the
splice clip.
—Crimp the clip firmly to the wire using
10" slip joint pliers. Do NOT solder the
splice (see Figure 14).
—Repeat this procedure for the second wire
or lead in the splice clip.
