Specifications

Output
120A

This Balmar 621 Series alternator is rated 120A at 12V. It uses a single foot spindle mount and a K6 serpentine pulley. The ground is isolated. Both the mount and the pulley type are fixed by the unit, so they are the first things to compare with your engine.

Our take

A 120A rating with an isolated ground and a K6 serpentine pulley describes a belt-driven 12V alternator on a single foot spindle mount. Compare the foot and the pulley with your engine, since both are set by the unit.
