Frequently Asked Questions
Will this fit my 1981 or newer Big Twin?
No — this regulator is specific to 1976-1980 Big Twin models. Newer years use different electrical systems.
What does a regulator do?
The regulator controls alternator output voltage to prevent battery overcharge and electrical system damage during operation.
Is this a direct bolt-in replacement?
Yes — it mounts directly in place of the original Harley regulator using the stock mounting points.
How do I know if my regulator has failed?
Signs include dim or flickering lights, a dead battery, or a battery that won't charge. A multimeter test at the battery terminals will confirm low or unstable voltage output.
