Troubleshooting Recommendations:
- Perform wiring checks of the wire connected to A22P1-12.
- If wiring checks are good, go to step 4.
- If wiring checks are not good, repair as required and do the close out.
- Make sure GS138 is properly grounded.
- If GS138 is not properly grounded, repair as required and do close out.
- If GS138 is properly grounded, continue with the next step.
- Perform visual check of A22P1-13. Make sure there is no wire connected to pin 13. Pin 13 is used for CPC 1 position.
- If fault indication is gone, do close out.
- If fault remains, continue with the next step.
- Interchange CPC 2 with CPC 1.
- Does the fault follow the CPC?
- If YES, replace the CPC 2 and do close out.
- If NO, continue with the next step.
- Do close out.
