I replaced the rotor, stator and reg/rect and it starting charging againat 13.5. So I decided to test my old reg/rectifer and after pluggin in the old unit it stops charging. Put the new back in and still no charging. It putting out 2v AC FROM THE STATOR now. Surely these systems aren't that fragile? So did I fry the rotor or reg/rect. and or the stator? thanks guys.
