Erratic Operation of Load Sensor - Troubleshoot
- Check all wiring for continuity and tight connections.
Expected Result: All connections are tight. There is a continuity in the wiring.
Results:
- OK: Go to 2.
- NOT OK: Wiring is open and intermittent or connections are loose. Repair wiring or tighten connections. STOP.
- OK: Go to 2.
- Check for electromagnetic interference (EMI).
- Remove ground loops. Shield all of the control wiring. The control wiring includes the load sharing line and the SPM-A synchronizer input. Route wiring away from noise source.
Expected Result: The load sensor is stable.
Results:
- OK: The problem has been resolved. STOP.
- NOT OK: Replace the load sensor. STOP.
- OK: The problem has been resolved. STOP.
- Remove ground loops. Shield all of the control wiring. The control wiring includes the load sharing line and the SPM-A synchronizer input. Route wiring away from noise source.
