I have an '03 660 Grizzly that keeps blowing the ignition fuse. I have unhooked the battery and hooked jumper cables from my 450 Rhino straight into the wires of the Grizzly and about 2 seconds after you turn the key on the fuse blows. With the battery hooked up, I can pull start it with the pull rope and it'll run about 2 seconds and blow the fuse. It was weird how it all started, we rode about 40 miles one evening with no problems. Killing and cranking it all evening. Rode back home killed it, about 5 minutes later got back on it and it wouldn't crank, acted like the battery was dead it would just click and buzz. Left it alone, the next morning it did the same thing. I pull started it, rode around to the back of my house and it started spittin and sputterin and back fired a few times and then it died. Thats when the ignition fuse started blowing. I've unhooked my digital display, power port (cigarette lighter plug) and battery and it still blows the fuse within 2 seconds of turning the key on (with jumper cables hooked to my Rhino) or pull starting it. Any pointers anyone can give me will be greatly appreciated.
Thanks, James

 

Sounds like you have a short somewhere. Inspect the electrical system for wires that have the coating worn off.
