About This Product
This 6-volt electronic relay from Samwel is a modern, solid-state solution for vintage charging systems. Designed as a two-post unit, it fits all 1926 to 1938 6-volt Harley-Davidson models equipped with a 3-brush generator. Unlike old mechanical regulators, this solid-state version offers more consistent voltage control and improved reliability. It is a direct replacement for OEM 4785-26. If you want to keep the original look, this relay can be paired with optional chrome or black covers. It is a smart upgrade for any pre-war rider looking for better electrical stability on the road.
Manufacturer part number: 0478502.
