How to Fix / Troubleshooting
Safety first: Ensure the generator is safe to start automatically before enabling AUTO mode.
- Check mode switch: Operate the AUTO/OFF/MANUAL selector several times. If the controller does not register changes, the switch or its wiring may be faulty.
- Inspect remote start wiring: For units with remote start contacts, verify continuity and correct wiring to the Hyundai Power controller terminals.
- Controller settings: Enter the controller setup menu and confirm that AUTO mode is enabled and that any schedule or remote start options are correctly configured.
- Input testing: Using a multimeter, test the mode switch contacts and wiring back to the control module. Replace the switch if defective.
