Procedure

    1. SUBTASK 72-32-37-350-058 Remove the Terminals from the NF Electrical Harness

    1. Refer to Figure and Figure.

      NOTE

      Harnesses are of sufficient length to allow the removal and replacement of the terminal three times only.

    2. Examine and identify the damaged terminals.

    3. Remove the damaged terminals. Move the sleeve marker carefully, if the distance between the sleeve on the terminal and the sleeve marker can not be kept within 0.95 in. to 1.02 in. (24 mm to 26 mm).

    2. SUBTASK 72-32-37-350-059 Install Terminals to the NF Electrical Harness

    1. Refer to Figure, Figure and Figure.

      2. Remove the insulations from the end as specified.

      1. NOTE

        Care must be taken to ensure that the wires are not damaged, because this will cause early failure.

    3. Put the terminal insulation sleeves over the cable.

      4. Put the wire into the terminal barrel ensuring a good contact, then crimp with crimping tool.

      5. CAUTION

        DO NOT APPLY A LOAD ON THE Y-SHAPED PORTION.

        Do the crimped joint pull check (cable size (A.W.G) 20).

        1. Use a Force gage.

        1. Apply load 17 N to 25 N (3.8 lbf to 4.7 lbf).

    6. Attach the terminal insulation sleeve over the terminal barrel.

      7. CAUTION

        DO NOT APPLY HOT AIR FOR MORE THAN 50 SECONDS.

        Heat-shrink the sleeve with a hot air gun, at air temperature of 770 deg F to 860 deg F (410 deg C to 460 deg C) after five minutes warm up period. Apply heat until the sleeve becomes transparent, continue heating for a further 10 to 15 seconds to ensure that the inner sleeve has fully heated and a plastic state is got. As soon as you have the above condition, stop hot air.

    3. SUBTASK 72-32-37-220-062 Examine the Repaired Areas of the NF Electrical Harness

    1. Refer to Figure and Figure.

    2. Visually examine for no signs of splitting and no heat damage.

    3. Dimensionally examine the cable length of the repaired harness.

    4. SUBTASK 72-32-37-750-056 Do the Test for Continuity and Insulation Resistance

      1. Do the test for continuity and insulation resistance.

      1. Refer to TASK 72-32-37-700-301 (TESTING-001).
