Troubleshooting Recommendations:
- Swap BATT feeder card with DC 1 feeder card. Does the fault follow the card?
- If YES, replace BATT feeder card and do close out.
- If NO, continue with next step.
- Remove BATT Feeder card in DCPC. Disconnect EM4 connector P407. Perform a resistance check for a short circuit as follows:
From To Result P407-4 P407-12 - If there is a short circuit, replace D5 and do close out.
- If there is no short circuit, continue with next step.
- Perform a continuity check as follows:
From To Result P407-3 Ground P407-11 Ground - If there is continuity, go to step 9.
- If there is no continuity, continue with next step.
- Perform a continuity check as follows:
From To Result P407-3 P431A-11 P407-11 P431A-10 - If there is no continuity, go to step 9.
- If there is continuity, continue with next step.
- Perform a resistance check on EM4 as follows:
From To Value Result J407-5 J407-4 562 Ω J407-4 J407-3 24 KΩ J407-12 J407-11 10 KΩ - If the resistance values are incorrect, replace EM4 and do close out.
- If the resistance values are correct, continue with next step.
- Perform a continuity check as follows:
From To Result P407-4 D5-Anode - If there is no continuity, go to step 9.
- If there is continuity, continue with next step.
- Perform a continuity check as follows:
From To Result P407-12 D5-Cathode - If there is no continuity, go to step 9.
- If there is continuity, continue with next step.
- Replace Diode D5. Is the fault resolved?
- If YES, do close out.
- If NO, continue with next step.
- Replace DCPC.
- Do close out.
