Frequently Asked Questions

Will this regulator fit my 2003 or 2006 Dyna?

This part is specific to 2004-2005 Dyna models. Check your year before ordering — other years use different regulators.

What does this regulator do?

The regulator manages the motorcycle's charging system, converting AC voltage from the alternator to DC to charge the battery and power electrical components.

Is this an OEM Harley part?

No — this is a Harddrive aftermarket replacement built to OEM specifications. It is not manufactured by Harley-Davidson.

Will this run cooler than the stock regulator?

Yes. The SCR technology and sealed encapsulation design allow cooler operation than many original regulators, especially during high-load conditions.
