Good To Know

Q: How do I know my regulator has failed? A: Common signs are a battery that will not hold a charge, dimming lights, or erratic instrument behavior while running. Testing charging voltage at the battery with the engine running is the quickest confirmation.

Q: Does this regulator need any programming? A: No programming is required; it plugs into the factory connector and regulates charging once installed. Confirm your model and serial number before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
