About This Product
This chrome-finished solid-state 12-volt voltage regulator from MCS is a modern electronic upgrade for vintage charging systems. It is designed to replace the original equipment, whether you have an early mechanical or a later electronic regulator. A unique feature of this unit is that it mounts directly to the generator in place of the stock end cover, simplifying your wiring and providing a cleaner look with its finned housing. The kit includes an armature support needle bearing for a complete installation. This regulator fits 1965 to 1969 Big Twin models and 1965 to 1977 XL Sportsters, and it naturally replaces OEM part number 977596 to ensure your classic Harley stays charged.
Manufacturer part number: 977596.
