put a new set of turn signals and replaced a broken right side fender strut night before last. yesterday when I'm riding to work I notice whenever I drop below 2000 rpm my tach lights blink dim then brighten up but the needle drops to nothing then bounces around. Once I get rolling again after 15 or 20 seconds my tach starts working again. When the tach falls off my turn signals stop working. Seems like the brake light is on and it drops off to the running lamp when I hit the brakes. wtf? this morning I get to looking at it and realize I pinched one of the brake light wires when I mounted the fender strut. The nut/bolt cut the coating and it was shorting out to the fender. I'll have to be more careful next time.
