Mike, headlights that dim significantly when the throttle is decreased usually indicate a charge system based on what is called a dual supply stator. These engines have 2 part internal "alternators", one part supplies heavy duty REGULATED charge current to the battery and the 2nd part supplies UNREGULATED power to the headlights only. Power produced from this winding (headlight brightness) depends totally on engine RPM.
p.s The power from the unregulated winding is AC power - not DC.
