I'll bet "BC Dan" knows this one...?
Last year, I was having issues with my bulbs burning out and finally all the lights including the lights on the tach and speedo went out. Turned out to be a bad ground from the hood over to the plug just in front of the chain case.
I'm having a similar problem now. My low beam burned out and the bulb only has about 6 hours on it. I'm getting a fluctuation in the lights depending on motor speed (more so than normal) while the motor itself runs just fine. I'm thinking it's the voltage regulator? I can't seem to find it to test the voltage coming out or to replace it.
Anyone have a different diagnosis or know where it is? The dealer says it's by the right foot but I don't see it there. I don't want to have to trace all the wires by looking at the wiring schematic if I can avoid it.
