I need help I have 2 CT90s that have been retrofitted with early 80 ct110 motors. I am having nothing but trouble getting the charging to operate correctly. I have tried new rectifiers and have tried different wire combinations to the rectifier, I have tried new batteries, but still I cannot get these to run with the headlight on. They will run all day long with no head lights. I have read many posts but nothing that helps me wire in this 80ct110 alternator into this 72/73 ct90 wiring systems. I have 3 wires coming out of the motor yellow/white/black-white. All 3 seem to have suitable AC voltages. Can any one out there give me a suggestion on how I should connect the three wires to my system?
