2005 XB12:
So I went out to fire up the trusty beast today and battery was dead - no worries there, it had been sitting idle for months, so I swapped a battery. As soon as I connected the terminals, the cooling fan came on (ignition 'off', run switch 'off')- strange, I think...

The bike had been running fine when it was last ridden...

Turn the key on, and immediately blow the ignition switch fuse - OK - may have a short in the switch harness, but that doesn't explain the fan running continuously.

Any Ideas? (before I go through wire by wire, thought I'd ask in case someone else has experienced this)

Thanks, JM

I only speak from my research as I recently bought a 08 Ulysses. I remember reading that such weird electrical ghosts have to do with the grounding wires/points (think there are 3 on this bike?). Anyway, do a good search within this forum as well as BuellXB.com, search grounding and electrical. Otherwise the community here is incredibly helpful & willing to go way out of their way, I'm sure someone more knowledgeable will reply shortly. 5 people in my area have offered to help me do 10K service on my bike, when I asked. Wow!

The fan coming on like that sounds like a grounding issue.

Sounds to me like you connected your battery terminals up the wrong way around, best go check and be prepared for some misery.
Good luck.

Loose grounds usually cause gremlins - a lesson learned from campaigning the 1125. Battery is connected correctly (I'm not at total newb) - I did find that the neutral circuit diode is bad, so that will get replaced... just hoping I don't dig in and find mice have been at work....

Been there, done that. Seriously, in a big garage full of all sorts of crap, you would think they could find something a little more appetizing than the insulation on the wiring harness for a rear tail lamp and bank angle sensor.
