No voltage to the headlamp. Fuse for headlamp is good. Also replaced relays. There is a hi and low beam switch on the left hand control bar as well as a turn signal switch and horn. Is there a way to test this switch? or just replace it if I can find one.

Thanks

No voltage to headlamp socket. 3.2 volts at fuse for headlamp. I pulled fuse out for accesaries while bike running and it stalled. Put it back in and fired right back up. I wiil have to take apart the left control switch to test it.

ACCEPTED

if you have 3.2 volts at the fuse, you already have an issue...make sure that circuit gets at least its supplied 11 - 12 volts current
