My gl1200 was charging at almost 17 volts, melting wires, looked at an alternator conversion (too much hacking) here is my fix, new battery $80.00, wiring stator kit from electrical conections. ( they know there stuff) $50.00, new HD voltage regulator (online parts house) $135.00. now charges around 14 volts with all the lights on and no hot wires.
