GRINDER
6.1 Troubleshooting the electronic governor system
1. When power is reaching the electronic governor the fuse light should be on.
If this light fails to go on, check the fuse, the battery connections, the wiring harness, and the indicator
lamp. If the fuse light is on, the wiring harness, battery connections, fuse and bulb are functioning
correctly.
2. Check the TUB (manual) MODE operation of the electronic governor. With the engine and hydraulic
systems at operating temperature, and the tub drive control valve in the forward position, throttle the
engine up to 1800‑2000 RPM.
With the mode switch in the tub position, the tub should be rotating. The speed of the tub can be varied by rotating the
tub limit knob. The number of tub speed lights which are lit will vary with the setting of the tub limit knob.
If the number of tub speed lights lit varies as you rotate the tub limit knob, the manual portion of the controls are
functioning correctly. Proceed to step 3.
If the manual portion is not working properly, proceed to trouble shooting table 6.1.
