If you’re restoring an old Harley—think Knucklehead, Hummer, or anything running a 6v Delco system—this voltage regulator is what you need.

It’s part number 74510-47A, a direct replacement for the Delco 1118995 style.

It’s brand new, unbranded but built to spec, and comes with a 60-day warranty.

Keeps your charging system in check so you’re not overcharging the battery or underpowering the lights.

Made for vintage bikes, so it’s got that classic look and function.

Whether you’re rewiring a basket case or just replacing a failed unit, this regulator gets the job done.

No modifications needed, just bolt it in.
