c. Wiring Repair Using Jumper Clips. Use the following procedure for temporary repair of a broken wire-wrapped wire.

Since this repair is only temporary, a new wire must be installed using the wire-wrap technique (paragraph e below) at the

earliest opportunity.

CAUTION

Exercise care when working around wire-wrap post to prevent damage to wiring and other wire-wrap

posts.

(1) Clip ends of broken wire as close to wire-wrap post as possible.

(2) When possible, remove broken wire from wire bundle. If removal is not practical, clip off ends of broken wire to

prevent contact with other connections and leave broken wire in bundle.

(3) Unwrap broken wire fragments from wire-wrap posts.

(4) Measure distance between two points to be connected and cut a piece of 30 AWG insulated wire approximately

one inch longer than distance measured.

(5) Strip insulation back 1/4-inch from each end of wire.

(6) Cut two 3/16-inch pieces of electrical heat-shrinkable insulation sleeving (Military Specification MIL-I-22129)

and slip sleeving over ends of wire and push up out of way.

(7) Place end of wire (see figure 3-13) between flat tab and body of jumper clip (Berg Electronics part no. 47539 or

equivalent) and bend tab against body.
