I have a 2000 Grizzly that blows the 20amp fuse when I try to start. The fuse holder runs to a relay, battry, and wire cluster that goes to the ignition. I have checked the wires and have not found a short. I did notice that the wires coming and going from the fuse holder are very hot. I'm assuming that it's over heating and blowing. What should I test/look at? Thanks
