hi there, i figured i'd add my fuse-blowing problem
i received a new tach from the dealer as a replacement ordered by the PO under warranty (but then the dealership was sold, the bike was sold, and i ended up having to fork over the $$$ for the tach, darn).
having the new tach wired up causes the 5A turn-signal fuse (#7) to blow, religiously, but only when the engine is running. i do indeed know the rules, and abide by them. last week i took the tach back off, removed the tank, poked around w/ the multi-meter to find obvious shorts in the turn-signal and tach wiring, found nothing, put everything back together, and the problem persists. and of course, disconnecting the tach fixes the problem
i've been working off of carl's amazing wiring diagram and i'm pretty sure i have the tach wired properly, but then again...
red/black -> +
black -> ground
yellow/black -> 1
yellow -> bulb
black (circle connector) -> tach mounting screw
the fuse simply blows, no melting or excessive heat as above. i can even hear it pop if the seat is off when i fire the bike up.
any ideas?
