Step Three: Strip the Insulation
When replacing a wire, use a wire of the same
size as the original wire or larger. The schemat-
ics list wire size in metric units. The following
t a b l e (see F i g u r e 6) shows the c o m m e r c i a l
(AWG) wire sizes t h a t can be used to replace
each metric wire size. Each AWG size is either
equal to or larger than the equivalent metric
size.

Figure 6 - Wire Size Conversion Table
To find the correct wire size either find the
wire on the schematic page and convert the
metric size to the AWG size, or use an AWG
wire gage.
If you
aren't
sure of the wire size, start with
the largest opening in your wire stripper and
work down until you get a clean strip of the
insulation. Be careful to avoid nicking or cut-
ting any of the wires.
Check the stripped wire for nicks or cut
strands. If the wire is damaged, repeat the pro-
cedure on a new section of wire. The two
stripped wire ends should be equal in length.
Step Four: Crimp the Wires
Select the proper clip to secure the splice. To
determine the proper clip size for the wire
being spliced, follow the directions included
with your clips. Select the correct anvil on the
crimper. (On most crimpers your choice is lim-
ited to either a small or large anvil.) Overlap
the two stripped wire ends and hold them
between your thumb and forefinger as shown
in Figure 7. Then, center the splice clip under
the stripped wires and hold it in place.
Figure 7 - Centering The Splice Clip
-Open the crimping tool to its full width
and rest one handle on a firm flat surface.
-Center the back of the splice clip on the
proper anvil and close the crimping tool
to the point where the former touches the
wings of the clip.
— Make sure that the clip and wires are still
in the correct position. Then, apply
steady pressure until the crimping tool
closes (see Figure 8).
Before crimping the ends of the clip, be sure
that:
—The wires extend beyond the clip in
each direction.
— No strands of wire are cut loose, and
— No insulation is caught under the clip.
Crimp the splice again, once on each end. Do
not let the crimping tool extend beyond the
edge of the clip or you may damage or nick the
wires (see Figure 9).
