The Tykick 74505-09 voltage regulator rectifier stabilizes charging output and replaces OEM part numbers like 74505-09/7450509A for select 2009–2014 Harley‑Davidson touring bikes.

If your Harley-Davidson is showing a weak battery charge, dimming lights at idle, or erratic electrical behavior, the regulator rectifier is a common service item. This Tykick unit is engineered to match OE dimensions and electrical characteristics for compatible Electra Glide, Road Glide, Road King, Street Glide, Tri Glide, Ultra and CVO models from 2009–2014. It cross-references established part numbers so you can verify fit before purchase.

How will this regulator rectifier affect my bike's charging system?

The regulator rectifier converts AC power from the stator to regulated DC voltage for the battery and electrical system. Installing a correctly matched unit helps maintain steady voltage under varied rpm and electrical load, reducing battery stress and protecting accessories. It does not modify performance but restores intended electrical stability.
