Troubleshooting Recommendations:
- Swap the right PRSOV with the left PRSOV. Is the fault still present?
- If NO, replace right PRSOV and do close out.
- If YES, continue with next step.
- Perform a continuity check between the PRSOV (P707), BMC 2 (A70), SPDA 3 (A15) and DAU 4 (A31) as follows:
From To Result P707-1 A15P3-H P707-2 Ground P706-1 A70P1-12 P706-2 Ground P706-3 A31BP1-H14 - If there is no continuity, repair defective wiring as required and do close out.
- If there is continuity, continue with next step.
NOTE: Remove all interface components for the short circuit to ground test on the wires that are not connected to a ground.
- Swap SPDA 3 with SPDA 1. Is the fault still present?
- If NO, replace SPDA 3 and do close out.
- If YES, continue with next step.
- Replace BMC 2.
- Do close out.
