Details

If you like traditional looks and reliable, modern performance, you’ll love this cool Flathead 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 1949-1953 Ford & Mercury Cars and 1948-1953 Ford Trucks with Flathead V8s and features a simple one-wire hookup.

We offer this one wire alternator in black painted or polished aluminum, and both include stock-appearing mounting brackets (the stock fan carrier bolts to that bracket) and pulleys that accept wide 5/8” belts.

  • Easy one-wire hookup
  • 65 amp idle, 75 amp cruise, 90 amp top end
  • 5/8" wide belt pulley included
  • If using 3/8" wide belt, order pulley # 91067178
  • Uses stock-appearing bracket and fan carrier bolts

Overall Assessment

Customers highly recommend this powergen for its authenticity, excellent fit, and ease of installation. Its aesthetic appeals to those looking for a vintage look, maintaining a stock appearance while enhancing performance. The conversion of vehicles from 6v to 12v significantly improves start time, lighting, and battery regeneration. Many have said they would buy the product again due to its trouble-free function and high quality. The unit is straightforward to install and simple to connect making it practical and user-friendly. It's praised for not having any warranty issues and enhancing the vehicle's overall performance. Customers, especially those with flathead motors, found the authentic look, great finish, and the fact that it works as expected, worth the price.

Polished Powergen Alternator 12 Volt

Purchased this Powergen Alternator several years ago. Have had absolutely no problems with it at all. Most people don't even know its an alternator, and not a generator. Looks like a chromed stock generator. Other an working perfectly, I like the way it keeps the stock appearance to the engine compartment. Being 12 Volts also helps giving me brighter lights and faster starts. This is the only way to go. SpeedWay Motors has them in stock for quick delivery. Buy with confidence.

Finally bit the bullet and ordered this, and I should have done so years ago. I have the strap Mount model and the aluminum bracket fit like a glove, impressive due to the machine work involved. I used a new 8g wire which I felt necessary (as directed by PM also). At idle (500rpms) it doesn't charge… at cruise 1900rpms she reads 14.2vdc on the gauge… as expected. Very nice product.

This replaced the stock generator on a 1953 Mercury that had been converted to 12V. It was a exact fit and cleaned up the engine compartment.

This powergen looks like a generator as it is suppose to, for that vintage look, I mounted mine on a offenhauser intake manifold on a flathead engine, the cradle mount did require a bit of trimming to fit properly

I want to be able to use this alternator with a vintage Stewart Warner 60 amp gauge. Being this unit is capable of 75 amps, can I use my 60 amp gauge, or do I need a gauge that registers higher? Thanks for any info.
