A possible cause of the Yamaha lithium G29 only running in reverse, despite having a new solenoid, new forward/reverse switch, and a fully charged battery, could be a fault in the direction switch circuit. According to the manual, if both forward and reverse signals are detected at the same time, it may indicate a Direction Switch Fault.

You should:
- Check the switch function by toggling from Forward to Neutral to Reverse and see if it feels consistent.
- Check the continuity of the switch to ensure it is working correctly.
- Use the diagnostic page of the App to verify the readings for both the Forward and Reverse switches.

If both signals are coming on simultaneously or if the Forward signal is not being correctly detected, the vehicle may default to Reverse.
