With the key switch off and the F-R switch in reverse the buzzer will sometimes ring, other times not. When it does not the solenoid is not pulled in. While sitting still and no one touching anything the solenoid will pull in and the buzzer sounds.
If the key switch is on, sometimes the solenoid pulls in, other times not. solenoid will drop out at random times as well, with no one changing anything.
When the solenoid is pulled in and if the key switch is on the cart will move in both the forward and reverse directions, however, the solenoid will randomly drop out again...
Is this more likely to be a solenoid issue, wiring short or a controller problem

Unplugged the speed sensor and all functions return to normal. Found another post on a different forum that had the same issue. Trouble shooting guide in the service manual leaves out checking this sensor??
