Re:arctic cat 400 electric problems help!!
The ONLY way to troubleshoot electrical problems is to find a wiring diagram and see what devices are on the circuits in question. OK, so maybe its not the only way, but your ****ing in the wind just "hunting" for loose wires. Get on google and search for a service manual for your particular bike. Give me the details about your bike and I'll try to find it too.
Anyway, if you find a wiring diagram you can chop up(figuratively, don't cut any wires) the electrical system and start isolating components/wires. I doubt a loose ground is causing you to blow fuses. As a ground connection degrades the resistance goes up causing the current to go down. More than likely you've got a bad electrical component or a nicked/scratched/cut wire.
Do you have a meter for checking voltage and continuity? Or just a test light? Or neither?
