Please help!!!! My '98, 95 Anniversary Ultra has recently developed a voltage "spike" issue. When this occurs, my headlight (low and high beam), passing lamps and radio/communication unit burn out. But no blown fuses except for the 5 amp on the ignition module. About 8 years ago I replaced the OE 36 amp stator and regulator with 45 amp units. No problems until this year. This has occurred 3 times this season. Any ideas on what causes the spike?
