Bizarre tachometer/electrical issues
Posted: Fri Sep 11, 2009 2:15 am
I have some electrical issues with my bike but I'm not sure if this is related or not. The problem is my tachometer will almost never reset itself to 0. When you turn the ignition on, it's supposed to do a self test go from 0 rpm to redline and back but instead it does weird back and forth motions and comes to a stop at random rpm values. Wherever it stops becomes the new 0 and the tach will rev up from that point. Here's a video showing the behavior:

The other electrical issue I have is that the fuse for the gauge cluster has blown twice in the last month so this may or may not be related.
Another electrical issue is my turn signal bulbs keep blowing (3 in the last two days... it's getting expensive.)
I'm not sure if this is normal but when I was looking for a short circuit by measuring the amps when the ignition was off (although there is no draw), I noticed that when I disconnect and reconnect the battery, the tach does the "self test" (although the rest of the gauge cluster doesn't come on like it does with the ignition.) I thought this was odd and maybe related in case it's not supposed to be doing that.
As for the bulbs blowing, I don't understand why either. I've measured the voltage going to the socket and it's within normal range. It only goes up to 14V when revving the engine a lot which I'd assume would be safe for the bulb.
