Having an issue with an over charging alternator. Seems to be putting out full power continuously. Last night at the strip it cooked the voltage regulator. I have tried both points and electronic regulators and finally cooked the points style last night. Im not sure if this could be a grounding problem or what. recently on another post i read some ohm resistance numbers, anyone have those handy? ( i did check the grounds today and everything seemed ok. car starts/runs fine, but amp meter is over in full charge. alternator is putting out 15 volts and the field wire has 12 volts at idle. as you raise rpm the field wire volts dont change much. i checked a friends car and his alternator was also putting out 15 volts but his field wire was down around 9 and seemed to change with rpm.
