    Powermaster 82155-2 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
    • Includes lamp terminal for (GEN) charge light
    • If using 3/8" wide belt, order pulley # 91067178
    • Uses stock-appearing bracket and fan carrier bolts

    Overall Assessment

    Customers commend our product for its traditional aesthetic, noting how it mirrors the classic generator design. This feature allows for easy installation in original mounting locations. The new alternator meets power demands effectively, even for non-stock functionalities like the A/C system. However, it should be noted, necessary wires for installation are not included. Despite this, consumers are exceptionally satisfied over its excellent performance throughout a year and more than 1,500 miles of driving. Our alternator offers superior utility, clearly surpassing the competition.

    It looks like the classic generator and uses the interior generator fault light for charging failures. Installation was same as removing and installing a stock generator except for upgrading/ replacing original wire from generator to starter solenoid and patching a wire from the no longer used voltage regulater to the new alternator terminal and installing new ground wire from engine block to alternator terminal. No wire or connecter are included with unit and 8 gage wire is required.

    I'm pretty much a stock freak with my 57 Thunderbird but the 45 amp generator could not keep up with the demands of the A/C system. (Yes, I know, the A/C is not stock). This alternator looks just like the generator and it fit very well in the original mounting location. To keep things looking original I left the regulator in place and hid the unused wires inside an electrical tape wrapping. I've now had the alternator in the car for over 1 year with about 1,500 miles of driving. No regrets what so ever.
