(2) Select the correct type of splice for the wire to be repaired:
- BS168 Splice, regular insulated for 16-22 AWG wire,
- 322326 Splice, thermocouple, parallel type, nickel,
- 2-323876-2 Splice, thermocouple, butt type, alumel,
- 2-323876-3 Splice, thermocouple, butt type, chromel.
(3) Select the correct crimp tool for the wire to be spliced:
- MR8-89-1 Crimp tool, regular wire splices,
- 46447 Crimp tool, thermocouple wire splices.
(4) Prepare the wire to be spliced.
(a) Measure the splice crimp barrel for the correct wire strip length.
(b) Examine the wire stripper to make sure the blades are sharp and aligned.
(c) Strip the insulation from the wire.
(d) Cut the conductor to the correct length. NOTE : The maximum space allowed between the splice and the wire
____
insulation is 0.12 in. (3.0479 mm).
(5) Crimp the splice onto the wire.
(a) Put the splice into the crimp tool.
(b) Put one end of the wire into the splice, the wire must be visible through the inspection hole in the splice.
(c) Close the handles of the crimp tool with an even pressure to crimp the splice onto the wire.
(d) Examine the splice to make sure the wire is correctly attached.
(6) Repeat steps 7.A.(2) thru 7.A.(5) for the other end of the wire.
(7) Do a continuity test on the repaired wire. Refer to 70-71-16. The wire must have continuity from end to end.
(8) Wind insulating tape around the splice until the tape is level with the wire insulation.

(9) Wind insulating tape around the splice area again for abrasion protection and to produce a moisture resistant seal.
(a) Wind the splice area with a layer of insulating tape.
(b) Each wind must overlap the last wrap by 50 percent.
(c) Wind another layer of insulating tape over the splice area in the opposite direction of the first wrap.
(d) The wind should extend 1 in. (25.3999 mm) beyond the end of the splice on both sides.
(e) Tie the ends of the insulating tape with the tying tape. For the tie use a clove hitch and a square knot.
8. Single Conductor Shielded Wire Repair_____________________________________ (Ref. Fig. 003)
A. Procedure
(1) Determine the size of the damaged area.
(a) If the wire is damaged or broken in one place, cut the wire at the center of the damaged area and repair as shown below.
(b) If a section of the wire/cable is damaged:
(2) Remove the insulated jacket for 2.5 in. (63.4998 mm) from the end of the wire to make the wire shield show.
(3) Cut a piece of the wire shield to cover the damaged area.
(a) Use the wire shield from the same type of wire.
(b) Cut a piece of repair wire shield to cover the splice area and to extend 1 in. (25.3999 mm) beyond on both sides.
(4) Make the repair wire shield large and install it over one end of the damaged wire. Then move it away from the splice repair area.
1_ Cut and remove the damaged section from the harness.
NOTE : See AWL Section 92-90 for wire type, gauge and length.____
2_ Cut a piece of replacement wire to extend to both ends of the
damaged area and repair as shown below.
