So, my bike is obviously still in the shakedown phase of it's post-build life. I've finally solved all of the leaks and drips and other mechanical problems, so it's only natural that an electrical problem should rear its head.
I've blown 3 30 amp main fuses in the last week, for no apparent reason. I've inspected every wire I can find, but I can't seem to locate any stripped insulation or obvious shorts... so I've got a few questions.
First: what systems are tied into that main fuse? Obviously the whole bike's electrical supply is controlled by that fuse, but if I were having a short in some subsystem wouldn't the associated fuse (fuel, lighting, etc) blow instead?
I've narrowed down what causes the fuse to blow, though I can't seem to replicate it when I've got the bike opened up for inspection.
Of the three fuses I've blown, the first blew while parking the bike. I'd ridden up on the sidewalk and turned the bike off, then I maneuvered it into a tight spot up against a wall. When I came back to the bike a few hours later, she was dead, and the main fuse was blown. It seems like the fuse blew while the bike was turned off, or at least not running. The next two times (both last night), the fuse blew during low-speed (city street) left hand turns. This leads me to suspect a few things. First, given that the bike seems to be able to lean left with no problems and go over gnarly potholes/bumps just fine without blowing a fuse, I think the short is somewhere in the bundle of wires that goes to the front controls of the bike and the ignition switch. Something about turning the bars to the left? Second, if the fuse blew while the bike was off, while I was maneuvering it into that spot (and turning the bars back and forth quite a bit to get it in), the short must be on some circuit that's hot when the bike isn't keyed to the "on" position.
So my second question: what systems in that area of the bike can blow the main fuse, and are capable of causing a short when the ignition is turned to the "off" position? The only thing I can think of, possibly, is the ignition switch harness itself.
What do you guys think? Any suggestions?
