320 amp S series alternator for early 5.9L Cummins - 1 wire turn on

Motor swap applications ONLY. This alternator comes with a single wire for 12v switched operation. This is perfect for moto swaps where the factory external regulator is not there or not desired.

The S series of 6 phase alternators offers incredible output in a compact and durable package. Highly efficient, these units use less horsepower per Kw of power produced than conventional 3 phase alternators. 12 diodes, twin rectifier plates and outstanding airflow ensure long service life, even in severe conditions.
