This Balmar 621 Series alternator is rated at 100 amps and 12 volts, with a single foot spindle mount, a K6 serpentine pulley and an isolated ground. It replaces the 621-100-SR-IG. The 1 inch Motorola-style mounting is typical for Westerbeke, Lehman, Hino and Pathfinder engines.
Our take
The isolated ground on the 621-100-K6 means the case is not tied to the engine for the return path, so the wiring has to carry it. It is rated at 100 amps and 12 volts on a single foot spindle mount.
