    Re: 1 wire alternators

    So... I jumped and I bought a 1 wire. 105 amp from dbelectrical for $68. The Mustang's starter came from them as well.

    The diagram below shows the alternator's output at various alternator rpm's. At idle (1100-1200 crank rpm) the alternator will be spinning 2700 rpm (2.45 times faster than crank rpm, based upon pulley size). According to the diagram, this will be in the neighborhood of 85 amps. More than the old alternator (assuming it was a 60 amp) put out at full tilt. Going down the highway at 2800-3000 crank rpm, it should easily be making it's full amperage.
