Arrowhead Harley-Davidson 12 Volt Regulator / Rectifier

This Arrowhead regulator/rectifier is a new replacement part designed to meet or exceed the original specifications for your Harley-Davidson motorcycle. It handles the critical job of converting the AC current from your stator into the DC current your battery and electrical system need, while also regulating the voltage to keep everything charged up properly. If your charging system isn't working right, this part is often the culprit.

Arrowhead built this unit with a robust design and well-made components, aiming for a long service life. It's a direct replacement for your stock unit, meaning it uses the same mounting points and comes with OEM-style connectors. This makes installation straightforward, often just a matter of plugging it in and bolting it up, without needing any special modifications. You can expect improved heat dissipation compared to some older designs, which helps with reliability, and better charging performance to keep your battery healthy.

This regulator/rectifier comes with a one-year manufacturer's warranty for your peace of mind.
