OLIFANT Voltage Regulator Rectifier for Harley Electra Glide & Road King 74505-02 — Direct-Fit OEM-Spec

OLIFANT 74505-02 is a direct-fit voltage regulator rectifier engineered to replace the factory unit on select 2002–2003 Harley-Davidson Electra Glide and Road King models.

This replacement regulator rectifier restores stable charging performance and protects your battery and electrical system by converting alternator output into steady DC voltage. Manufactured to match the fit and electrical specifications of the original equipment, the OLIFANT 74505-02 is intended for riders who need a reliable swap-in part for late-model 2002–2003 Harley touring bikes.

Which Harley models does the 74505-02 fit?

The 74505-02 is compatible with a range of 2002–2003 Harley-Davidson touring models. It fits Road King, Road King Police, Road King Classic, Electra Glide (standard and Classic), Electra Glide Police, Road Glide, and Ultra Classic variants listed by factory model code.

• Road King FLHR, FLHRI (2002–2003)
• Road King Police FLHPI and Road King Classic FLHRCI (2002–2003)
• Electra Glide FLHT, FLHTC, FLHTCI, FLHTPI (2002–2003)
• Road Glide FLTRI and Ultra Classic FLHTCUI (2002–2003)

How does this part improve charging and electrical reliability?

The regulator rectifier takes the AC current produced by your stator and converts and regulates it into steady DC to charge the battery and run electronics. A failing unit can cause undercharging, overcharging, or erratic electrical behavior; replacing it with a properly spec'd unit restores stable voltage control.

• Converts alternator AC to regulated DC output
• Helps maintain proper battery charge levels during idle and riding
• Prevents voltage spikes that can damage accessories and the battery
• Designed to meet OEM electrical connection and mounting points

What should I check before buying and installing the regulator?

Verify the part number and visually compare the connector type, mounting holes, and wiring to your original regulator. Also inspect for symptoms of regulator failure—dimming lights, battery drain, or charging voltage outside the manufacturer’s range—so you confirm replacement is necessary.

• Confirm part number 74505-02 matches your old unit
• Compare connectors, mounting pattern, and physical dimensions
• Measure charging voltage with a multimeter before and after replacement
• Check stator health; a bad stator can damage new regulators

Is installation difficult and what tools are typically required?

Installation is straightforward for a mechanic or a rider with basic mechanical skills and standard hand tools. The unit mounts to the frame or designated bracket and connects to the factory harness; follow service manual torque specs and wiring routing for a safe fit.

• Common tools: socket set, torque wrench, screwdrivers
• Disconnect battery before starting to avoid shorts
• Securely fasten mounting bolts and ensure connectors are fully seated
• Verify charging voltage after installation during an engine run

Who this is for: The OLIFANT 74505-02 is aimed at owners and technicians of 2002–2003 Harley-Davidson Electra Glide and Road King touring motorcycles who need a reliable, direct-fit regulator rectifier replacement. It suits riders repairing charging-system failures, performing routine electrical maintenance, or restoring touring bikes to dependable operation. Always match the part number and inspect related charging components before installation to ensure a successful repair.
