    Powermaster 82155 Details

    If you like traditional looks and reliable, modern performance, you’ll love this cool 1-wire alternator. It has the look of an original generator, but is really a 12-volt, negative-ground alternator that produces 65 amps at idle and 75 amps going down the road. This model is designed to fit 1956-57 Ford Thunderbirds and features a simple one-wire hookup.

    We offer this one wire alternator in a black powder coat finish with included stock-appearing mounting brackets (the stock fan carrier bolts to that bracket) and pulleys that accept wide 1/2” belts.

    • Easy one-wire hookup
    • 65 amp idle, 75 amp cruise, 90 amp top end
    • 1/2" wide belt pulley included
    • If using 3/8" wide belt, order pulley # 91067178
    • Uses stock-appearing bracket and fan carrier bolts
