GM PowerGen Generator to Alternator Conversion

Powermaster has produced a good looking alternator built into a generator case. This will give you great low RPM output. No more dimming lights at idle. These units can produce 75 amps and are a simple 1-wire hookup. They have built-in voltage regulators so the only connection is the output battery cable. These are all 12 volt negative ground units.

The Short GM unit is 6.25 inches between the mounting ears and the Long GM is 7.125 inches between the mounting ears. For vehicles that have the P/S units driven off the rear of the OE generator, you would have to install a separate P/S pump.
