SUBTASK 24-21-43-820-001 Calibration Procedures for Test Equipment
Set the supply voltage to be 250 volts DC, on the Megger Insulation Resistance Tester - BMM80, 250 Volts (200 Gohms) or equivalent.
Connect the Megger Insulation Resistance Tester - BMM80, 250 Volts (200 Gohms) or equivalent test leads, between the connector body and each pin of the connector.
Make a note of the resistance values.
Pin to Earth - The insulation resistance should be 20 megohms minimum.
If the resistance values are not between the limits, reject the harness. The limits are as follows:
SUBTASK 24-21-43-750-001 Do a Test to Find the Insulation Resistance Value of the IDG Cable Assembly
Set the Multimeter to the continuity setting.
Connect the Multimeter test leads to the contacts at the ends of each wire.
Make sure that the Multimeter shows continuity. If the Multimeter shows no continuity, reject the harness.
