As another thread says I'm alsonew here but if someone here
can't help i'm really in trouble.

Formula MX 87 has new voltage reg, lighting coil, & key switch.
The lights are too dim & not enough power to make gas gauge to work either. If I unplug reg, and rev the engine it will easily pop the brand new bulb I had put in when I restored this machine. this was part of the reason I only paid $200 for it. Does anyone have wiring dia, or any ideas.

Yeah, check to make sure that there isn't a bare wire somewhere that'd be shorting out the system. That'd be my first check. Good luck and let us know what you find.

Thanks to all who looked at this thread and to the relpys. Turns out the whole problem was the original key switch which shorted out the new voltage reg. After striping entire harness and still not finding a shorted wire, tried another reg. and all works fine now. How often do you need to replace a new part with another new part. Best part is now my girlfriend will have a machine to ride this weekend. Thanks again.
