I need help. My 3 wire GM alternator is putting out 14+ volts and 115amps at the alternator. However, when I measure the amperage across the +/- ammeter wires (disconnected from the gauge) I am getting 5amps. The gauge reads in the negative when the car is running, a pegs further down the more I turn on, but the lights don't dim and the output at the alternator does not change.
What do I need to do to sort this out, apart from take it to an auto electric shop.... last resort, that.
