Hi and welcome to JustAnswer,Thank you for the question and your patience. Should you still need assistance for information purposes only... Initially and if have not been tried; inspect the battery, its ground lines and/or check/clean the battery cables + terminals, connectors and wiring as a preliminary consideration. Have the battery externally charged and then LOAD TESTed (even if new/charged and just for the purpose of eliminating it as a suspect). Consider/try a review of the basics (again if have not been done)• do an Ohms' test with all 3 pairings of the stator wires as these should show very low resistance on any/all pairing;• however, none of the stator wire should show any resistance to the engine ground;• with the engine running at high RPM, any/all pairing of these stator wires should produce ~55 Volts AC;• any deviation and the stator would be highly suspect;• if all of the above check good, then the regulator/rectifier combo would be the most likely suspect;• repeat the above tests with the fan running,
