Possible Causes
Active fault not cleared, Safety interlock (door or panel switch) open, Faulty neutral safety or gear position switch (if equipped), Control board logic fault
How to Fix / Troubleshooting
Safety first: Ensure the generator is isolated from the load and cannot start unexpectedly.
- Check for active alarms: Scroll through the controller menu for any active alarms (low oil, overtemp, etc.). Clear them according to Yamaha instructions before attempting to start.
- Inspect access panel switches: Some Yamaha standby units have door or panel interlock switches. Ensure all panels are properly closed and latches engaged.
- Test interlock switches: Use a multimeter to verify continuity when panels are closed. Replace any defective switches.
- Controller reset: Power-cycle the controller by disconnecting the battery for a few minutes, then reconnect. If E13 persists, the control board may be faulty.
- Contact service: For persistent crank inhibit with no obvious cause, have a Yamaha technician evaluate the control logic.
