Frequently Asked Questions

Is this the same as the original Harley regulator?

Yes — this is a direct OEM-spec replacement for part 74505-09 and meets or exceeds original equipment standards.

Will this fit my 2017+ Touring?

No — this regulator is for 2009-2016 Touring models. 2017 and newer use Milwaukee-Eight engines with different electrical specifications.

Why does this regulator run cooler than others?

The SCR (Silicon Controlled Rectifier) technology and sealed, high-temperature circuit board minimize thermal impedance and dissipate heat more efficiently than standard designs.

Do I need any additional wiring or adapters?

No — the OEM-grade wiring harness is included and connects directly to your bike's stock electrical system.

Is installation difficult?

Regulator replacement is typically a straightforward bolt-on job. Consult your service manual for torque specs and routing if you're unfamiliar with electrical work.
