I just picked up an 03 XB9S. It is my third Buell and I love it!

Now for the issue. When I was driving home from buying it the ACC fuse blew and knocked out the low beam, gauges, tail light, and blinkers. I have since replaced the fuse(many times) but the problem has gotten worse. Now I can't even turn the key "ON" without the fuse blowing. I've gone through the tail and flyscreen wiring including the headstock pass through to no avail.

I've tried to eliminate as much as possible. I have disconnected the:
Headlight(white plug under flyscreen)
Blinkers
Tail light

The fuse continues to blow when the key is turned to "ON". Could this be a bad ground issue? Is there any way to test for a short to to narrow down where it is coming from? I'm admittedly terrible with electrics and fake my way around a Fluke tester unconvincingly.
