Joecdeere, I viewed a thread where you helped with a Gator TH6x4 electrical problem. I have the same 30 amp fuse for glow plug blowing. The glow plug light comes on for 6-8 seconds, and the relay clicks a second time at 20-30 seconds so I think the relay is good. Why would the fuse blow each time power is turned on? A short/grounded hot wire? Thank you for helping me.
