I have a Bobcat Three Phase with a Kohler CH20s engine. I am having an issue where the motor is running way too fast. I have gone through the steps of adjusting the governor and adjusting the run speed as prescribed in the manual with no success. I can manual move the governor arm over and drop the rpms to acceptable levels but it does not move on its on. My thoughts are it may be the internal portion of the governor that is not operational.
However, in the run-idle position, the motors does not come down to idle position without manually moving the governor arm.
Its running at such a high speed it has melted the wire going to the large R2 resistor mounted on the upright.
Any trouble shooting ideas before I tear into the motor?
