Troubleshooting Recommendations:

  1. Disconnect cockpit printer connector (A241P1) and perform a 28 VDC and ground check as follows:

    From To Expected result Result
    A241P1-A Ground 28 VDC
    A241P1-C Ground Continuity
    A241P1-K Ground Continuity
    A241P1-d Ground Continuity

    1. If voltage or ground are not present, investigate wiring or power source from SPDA 1 and do close out.
    2. If voltage and ground are present, continue with next step.

  2. Disconnect ADLU connector (A239BP1). Perform a continuity check as follows:

    From To Result
    A241P1-KK Ground
    A241P1-LL Ground
    A241P1-KK A241P1-LL

    1. If there is continuity, repair defective wiring as required and do close out.
    2. If there is no continuity, continue with next step.

  3. Perform a continuity check as follows:

    From To Result
    A241P1-KK A239BP1-C1
    A241P1-LL A239BP1-D1

    1. If there is no continuity, repair defective wiring as required and do close out.
