- 322326 Splice, thermocouple, parallel type, nickel,
- 2-323876-2 Splice, thermocouple, butt type, alumel,
- 2-323876-3 Splice, thermocouple, butt type, chromel.
(6) 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.
(7) 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).
(8) 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.
(9) Repeat steps 8.A.(5) thru 8.A.(8) for the other end of the wire.
(10) Do a continuity test on the repaired wire. Refer to 70-71-46. The shield must have continuity from end to end.
(11) Cut the wire jacket and shield. Make sure that 1 in. (25.3999 mm) of the wire shield is shown.
(12) Move the piece of the repair wire shield over the splice area.

(13) Make sure the repair wire shield touches the shield of the wire.
(14) Wind the repaired wire shield for abrasion and moisture protection.
(a) Wind the repair wire shield 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 repaired wire shield in the opposite direction of the first wrap.
(d) The wind should extend 1 in. (25.3999 mm) beyond the end of the repair area 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.
(15) Do a continuity test on the repaired wire shield. Refer to 70-71-46. The shield must have continuity from end to end.
9. Multi-Conductor Shielded Wire Repair
____________________________________
(Ref. Fig. 004, 005)
NOTE : Multi-conductor means wires with more than one conductor. Two, three,
____
and four conductor cables are multi-conductor wires.
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: 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.
(2) For both the damaged and replacement cables.
(a) Remove the insulated jacket from the wires for 4 in. (101.5998 mm) to 6 in. (152.3997 mm) from the ends.

(c) Cut the wires so that the conductor ends are offset by 1.875 in. (47.6249 mm).
(3) Cut a piece of wire shield to cover the damaged area.
(a) Use the 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.
(5) Select the correct type of splice for the wire to be repaired: 中国航空网 www.aero.cn 航空翻译 www.aviation.cn 本文链接地址：A320飞机维护手册 AMM STANDARD PRACTICES - ENGINES(30)
