Possible Causes
Faulty auxiliary contact on main contactor, Broken feedback wire between contactor and control board, Misaligned contactor mechanism, Defective input on control board
How to Fix / Troubleshooting
Safety first: Turn off power at the breaker before opening the charger.
- Locate contactor: Identify the main contactor on the power board and its auxiliary feedback contacts.
- Check wiring: Ensure the small‑gauge wires from the auxiliary contacts to the control board are intact and firmly connected.
- Mechanical inspection: With power OFF, gently operate the contactor manually (if possible) to ensure it moves freely.
- Test continuity: A technician should test the auxiliary contacts for proper open/close behavior.
- If auxiliary contacts are faulty: Replace the contactor assembly. If contacts are good, the control board input may be defective and require replacement.
