Bike keeps popping main fuse

I just replaced the stator and R/R. Heck of a job. Bike ran fine for a couple days. I was at work and needed to move my bike over. I switched the ignition on, shifted to neutral, and moved the bike. Suddenly the fuse popped. Replaced the fuse, started the bike up, few seconds later blew the fuse again. Any ideas?

On a separate note, after replacing stator, the bike appears to be running at higher rpms. I was running 5k rpms at 70 mph.

Help or advice would be appreciated. Just got this bike as my first 5 months ago. 2001 vulcan 750. Pretty dejected with it so far.

I'm not sure about the fuse popping but you can check all the ground connections to make sure they are good. As far as the RPM, my bike has always ran 5k RPM at 70mph.

Look over the main wiring harness. Mine was rubbing on a screw head aft of the battery box where the harness crosses from one side of the bike to the other. It was tied down too tight. Also check inside the headlight cowling. Lots of wires in there. Just takes the smallest nick to pop that fuse. I loosened up the harness and problem solved. Never have figured out which wire in the harness was shorting out.

Mine did that too, I found a wire rubbed through where it goes under the gauges. It popped every time I turned the handle bars to the far right.

Thanks, I'll have to check. I did turn the handlebars hard to move it. Will post what I find.

Shark88,

Do you remember which wire it was? That's what is happening with my bike. Every time I turn the bike handlebars hard right, it pops the main fuse. I don't see any stripped or exposed wires, so still stumped.

Thanks

I think it was a yellow wire that was on the harness running around up to the gauges, not sure exactly if I had to pull the headlight off to see it or not, but it would be a good idea to check everything around it.
