Possible Causes
Relay contacts welded due to short circuit, Mechanical failure of internal contactor, Incorrect installation causing overcurrent, Faulty relay drive circuit on control board
How to Fix / Troubleshooting
Warning: A welded relay can leave the output live even when charging is stopped. Disconnect power at the breaker before inspection.
- Verify de-energization: With the breaker OFF, confirm no voltage at the vehicle connector using a multimeter or EVSE tester.
- Inspect relay module: Open the charger and locate the main power relays/contactors. Look for discoloration, melted plastic, or a burnt smell.
- Check relay operation: With power restored and under controlled conditions, start and stop a charge while listening for relay clicks. If the charger reports open but voltage remains at the output, the contacts are welded.
- Replace relay or power board: The main relay assembly is not usually serviceable at component level. Replace the entire relay module or power board according to go-e service documentation.
- Investigate cause: Check for signs of short circuits in the output wiring or vehicle connector that may have caused the welding, and correct before returning to service.
