Blows Main Fuse at 1/4 Throttle???

You could prove out the overcharge theory by disconnecting the alternator temporarily and run on battery. Still blows the fuse? Short somewhere and how it relates to the throttle is beyond me. Fixes problem? I'd change the regulator.

Good Idea!

I will disconnect it in the next few days when I change out my starter.......Time to get back to work and prepare for NEW YEARS!!
