General

Fig/item numbers in parentheses in the procedure agree with those used in the IPC. Only the primary Fig/item numbers are used. For the service bulletin alpha variants refer to the IPC.

If the voltage supplied is in the limit of 24 volts DC, you can use the alternative procedures for the continuity test.

Procedure

    1. SUBTASK 71-52-43-750-054 Do the Continuity Test on the Wires

    1. Connect the Lamp and battery tester - 4.5 volts DC to the contact at the ends of each wire in turn.

    2. Make sure the lamp comes on which shows continuity.

    3. Reject the cable, if the lamp does not come on which shows no continuity.

    4. Lightly bend or pull the cable.

    5. Reject the cable, if the lamp goes off.

    2. SUBTASK 71-52-43-750-055 Do the Insulation Resistance Test on the Cables

      NOTE

      The test voltage is to be 500 volts DC.

    1. Connect one test lead of the Megger - 500 volts DC to the body of connector. And connect other test lead to the pin or socket of connector in turn.

    2. Measure the insulation resistances.

    3. The resistances must be more than 20 megohms.

    4. Lightly bend or pull the cable. And make sure the resistances do not become less than 20 megohms.
