Electrical Issues - Help!
I left my bike for a week in an underground parking lot. I noticed when I parked it the HID low beam was flickering( I don't think this is related buy I'll mention everything I have noticed).
I arrived back last night and found the battery almost dead. The clock was not showing but when the key was turned there was a very faint glow to the red indicator lights on the dash.
This morning I gave it a boost to get me on the way and noticed the HID light is now dead. High beam still worked so used that for the trip home. I pulled out of the garage and got on my way. About every 22 miles the power would die, tach/speedo drop to zery, for an instant, and back again. It was as if the bike died but I was going with enough momentum to bump start her and she would continue to go fine.
An hour and half into the ride home I had to stop at a toll booth and she died. It didn't seem to charge during the last hour and a half and only had enough juice to make her click but not turn over. I pushed her out of the way and gave her a boost again. When I pushed her off the center stand I put the brake on and she died again. Aha! Pulling the brake lever killed her! I boosted her again and without touching the brake took off again. Another couple hrs later and I had to get fuel so was able to gear down and get to the pumps. During the last two hour stint I experimented by pulling on the brake handle and pushing on the brake pedal and the electrics would die, and the bike, and bump start again when released. Got fuel, boosted again and away I went. Made it back to the house and when I got in the driveway I pulled the brake lever and, you guessed it, she died.
I boosted her in my garage and pulled the brake circuit fuse to see if that would isolate anything but when I pulled the lever again, she died.
I mentioned earlier that every 22 miles she would die instantaneously and start up again while on the move. The radio would kick out and kick back on just like there was a dead short for only a second.
Does a computer tied to the brake system run a diagnostic check every 22 miles that would run power through the brake system?
It seems as if there is something in the brake system that is shorting out but then why did pulling the fuse do nothing? Is the fuse simply for the lights? Could there be other electrics that are in the brake system but have nothing to do with the brake lights?
It seems like something is shorted and draining the battery as well. When the brake system is engaged it becomes an instant dead short and everything dies, quickly!
I'm at a loss and hope someone else may have seen these symptoms before. Any help would be appreciated.
