Troubleshooting Recommendations:
- On the DC synoptic page, make sure ESS TRU2 icon is green and is supplying 28 VDC.
- Get access to the DCPC contactor K3.
- Disconnect contactor K3 connector P404.
- In the cockpit, turn the BATT MSTR SW to ON.
- Perform a check for 28 VDC as follows:
From To Result P404-1 Ground P404-2 Ground - If there is 28 VDC, go to step 8.
- If there is no 28 VDC, continue with next step.
- Disconnect EM4 connector P407. Perform a check for 28 VDC as follows:
From To Result P407-23 Ground - If there is 28 VDC, continue with next step.
- If there is no 28 VDC, go to step 16.
- Perform a continuity check as follows:
From To Result P407-25 P404-1 - If there is continuity, replace EM4 and continue with next step.
- If there is no continuity, go to step 16.
- Perform a continuity check as follows:
From To Result P404-5 Ground P404-7 Ground - If there is continuity, repair defective wiring and continue with next step.
- If there is no continuity, go to step 16.
- Remove PLC 1, PLC 2 and PLC 3.
- Perform a continuity check as follows:
From To Result P404-6 Ground P404-8 Ground P404-22 Ground P404-3 Ground - If there is continuity, go to step 16.
- If there is no continuity, continue with next step.
- Perform a continuity check as follows:
From To Result P404-3 P110C-27 P404-6 P110A-21 P404-8 P110B-13 P404-22 P110C-21 P404-3 P210C-27 P404-6 P210A-21 P404-8 P210B-13 P404-22 P210C-21 P404-3 P310C-27 P404-6 P310A-21 P404-8 P310B-13 P404-22 P310C-21 - If there is no continuity, go to step 16.
- If there is continuity, continue with next step.
- Install PLC 2 and PLC 3. Is the fault resolved?
- If NO, install PLC 1 and continue with next step.
- If YES, replace PLC 1 and do close out.
- Remove PLC 2. Is the fault resolved?
- If YES, replace PLC 2 and do close out.
- If NO, install PLC 2 and continue with next step.
- Remove PLC 3. Is the fault resolved?
- If YES, replace PLC 3 and do close out.
- If NO, continue with next step.
- Replace K3.
- If system checks are good, do close out.
- If fault remains, continue with next step.
- Replace DCPC.
- Do close out.
