Sparking throttle cable; and blowing lite bulbs

[Dcuzz23]

:shrug: well i went ridin for like the fourth time since i got my shee back together and im still working out the kinks. i installed ricky stator 200wstator,voltage regulator,cdi, adj. plate, and enhanced flywheel. the problems im having is where the throttle cable rubs on the little metal bar attached to the top steering stem clamp has rubbed its way through the rubber jacket and the metal underneath the rubber outside coating is rubbing the metal bracket and arcing is taking place when they contact eachother. also i have a voltage problem cause i keep blowing up mr-16 lamps with 24volts add high rpm. when i test voltage between the throttle cable and the metal bar it arcs to im getting 6volts. i checked for pinched wires in the harness and there is none. i m pretty sure i hooked up the voltage regulator correctly. i put the yellow wire of the regulator to the blue wire the old one was hooked up to and grounded the brown to the frame. is the brown wire NOT supposed to be hooked up to ground? i am at a loss for words. kinda wierd to me. the bike runs fine and when the arcing does take place there is no effect in performance.
