Troubleshooting Recommendations:

  1. Make sure there are no AC BUS 3 related failure messages.

    1. If there are AC BUS 3 related failure messages, troubleshoot AC BUS 3 first and do close out.
    2. If there is no AC BUS 3 related failure messages, continue with next step.

  2. On the Cockpit Circuit Breaker Panel (CCBP), verify the status of AC BUS 3 thermal circuit breaker CB-C5 'AV BATT CHGR'.

    1. If it is IN, go to step 4.
    2. If it is not IN, continue with next step.

  3. Remove the AV BATT Charger. Set CB-C5 to IN. Did the thermal CB stay IN?

    1. If YES, replace defective battery charger and do close out.
    2. If NO, go to step 7.

  4. Swap the AV BATT Charger with the APU BATT Charger and apply power to the A/C. Is the fault message still present?

    1. If NO, replace the AV BATT Charger and do close out.
    2. If YES, continue with next step.

  5. Set CB-C5 to OUT. Access the CCBP. Apply power to the A/C and perform a 115 VAC voltage check as follows:

    From To Result
    CB-C5-A1 Ground
    CB-C5-B1 Ground
    CB-C5-C1 Ground

    1. If there is no 115 VAC on all phases, troubleshoot the missing phase(s) from AC BUS 3 upstream of CB-C5 and do close out.
    2. If there is 115 VAC on all phases, continue with next step.

  6. Set CB-C5 back to IN. Perform a 115 VAC voltage check as follows:

    From To Result
    CB-C5-A2 Ground
    CB-C5-B2 Ground
    CB-C5-C2 Ground

    1. If there is no 115 VAC on all phases, replace CB-C5 and do close out.
    2. If there is 115 VAC on all phases, continue with next step.

  7. Remove power from the aircraft. Set CB-C5 to OUT. Disconnect the AV BATT Charger connector A181P1 and perform a continuity check as follows:

    From To Result
    CB-C5-A2 Ground
    CB-C5-B2 Ground
    CB-C5-C2 Ground

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

  8. Perform a continuity check as follows:

    From To Result
    CB-C5-A2 A181P1-A
    CB-C5-B2 A181P1-B
    CB-C5-C2 A181P1-T

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

  9. Access the DCPC logic assembly. Remove the BATT/RAT Interface card and perform a continuity check as follows:

    From To Result
    A181P1-M Ground

    1. If there is continuity, repair defective aircraft wiring as required or replace DCPC if failure is in DCPC and do close out.
    2. If there is no continuity, continue with next step.

  10. Perform a continuity check as follows:

    From To Result
    A181P1-M P410A-7

    1. If there is no continuity, repair defective aircraft wiring as required or replace DCPC if failure is in DCPC and do close out.
    2. If there is continuity, continue with next step.

  11. Replace the BATT/RAT Interface Card in the DCPC.
  12. Do close out.
