JUMPER WIRE ASSEMBLY
Refer to Pictorial 1-10 for the following steps.
(
)
Remove 1/4" of insulation from one end and 1/8"
of insulation from the other end of a 12" red
wire. Twist the strands at each end of the wire
tightly together. Then melt a very small amount
of solder on these ends to hold the fine strands
together.
(
)
Solder a spring connector onto the 1/8" bare end
of the prepared red wire as shown.
(
)
Insert the spring connector on the red wire into
the center hole of a 3-connector shell. Be sure to
position the socket with the slotted side up and
the spring connector with the small tab up as
shown. The connector will lock into place
when you have it properly inserted in the shell.
Set the jumper wire assembly aside until it is called
for.
