Procedure

    1. SUBTASK 23-44-41-750-053 Calibration Procedures for Test Equipment

    1. All test equipment used must have a valid Calibration Certificate.

    2. SUBTASK 23-44-41-750-054 Do the Test to Check the Insulation Resistance on the Maintenance Interphone Jack Harness (Refer to Table 1)

    1. NOTE

      Make sure you use the negative contact on the connector shell and the positive contact on the pins.

      Refer to Figure.

    2. Set the supply voltage, on the Insulation Resistance Tester, to 250 volts.

      3. Connect the insulation resistance test leads, between the connector body and each contact of the connector.

      1. Contact to Contact - The insulation resistance must be more than or equal to 20 megohms minimum.

      2. Contact to Connector Shell - The insulation resistance must be more than or equal to 20 megohms minimum.

      3. If the Insulation Resistance Tester shows an incorrect value, reject the harness.

    3. SUBTASK 23-44-41-750-055 Do the Test for Continuity of the Maintenance Interphone Jack Harness (Refer to Table 1)

    1. NOTE

      Different methods can be used for continuity testing but in all cases the maximum voltage allowed is 24 volts DC.

      Refer to Figure.

    2. Set the Multimeter to the continuity position.

    3. Connect the Multimeter test leads to the contacts at the ends of each wire.

    4. Make sure that the Multimeter shows continuity. If the Multimeter shows no continuity, reject the harness.

    5. Do Step and Step for all wires in the cable assembly.

    4. SUBTASK 23-44-41-750-056 Do a 4 Wire Low Resistance Ohmmeter Test (BT51)

    1. Refer to Figure.

    2. Connect the ohmmeter leads between the connector and backshell. The resistance must be less than or equal to 5 milliohms.

    3. If the ohmmeter shows an incorrect value, reject the harness.
