Procedure

    1. SUBTASK 71-51-42-750-052 Do the Test to Find the Insulation Resistance Value of the EEC and Ignition Supply Harness

    1. Refer to Table.

      2. Connect the Megger - 250 volts DC or equivalent between each connector body and all the contacts within the connector. This check must be carried out for all connectors.

      1. Accept resistances more than 20 megohms.

      2. Reject resistances less than in Step.

      3. Lightly pull or bend the cable. Make sure the resistances do not become less than 20 megohms.

      3. Connect the Megger - 250 volts DC or equivalent between each contact and all the other contacts within the connectors.

      1. Accept resistances more than 20 megohms.

      2. Reject resistances less than in Step.

      3. Lightly pull or bend the cable. Make sure the resistances do not become less than 20 megohms.

    2. SUBTASK 71-51-42-750-053 Do the Test for Continuity of the EEC and Ignition Supply Harness

      NOTE

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

    1. Refer to Table.

    2. Connect theLamp and battery teter - 4.5 Volts DC to each end of the cable circuit.

      3. Reject the harness if the light does not come on which shows no continuity

      1. Accept cable circuits where the test lamp comes on.

      2. Reject all circuits where the test lamp does not come on.
