The Powermaster 150 Amp alternator is a high-output, internally regulated upgrade for 1960–1987 Chevrolet C10 trucks. It uses a one-wire hookup, a six-groove pulley and a heavy-duty rectifier, and it comes with a polished finish and a modern housing. The 150 amp output is well above a stock alternator, so it suits trucks with added electrical load: big audio, electric fans, winches or extra lighting. Buyers rate it highly, though the polished housing and one-wire setup draw some mixed comments.
