OLIFANT Voltage Regulator Rectifier for Harley Electra Glide & Road King 74505-02 — Direct-Fit Replacement, Stabilizes Charging

OLIFANT 74505-02 is a direct-fit voltage regulator rectifier built to replace the OEM unit on select 2002–2003 Harley-Davidson Electra Glide and Road King models, stabilizing charging output and protecting the battery and electrical system.

This replacement regulator-rectifier is designed as a bolt-in unit for several Harley touring bikes from the 2002–2003 model years. It converts alternator AC to regulated DC and helps maintain steady charging under typical riding conditions. Before installing, compare the part number and connector shape with your existing module to ensure compatibility.

Which Harley models does this part replace?

The OLIFANT 74505-02 is compatible with many 2002–2003 Harley touring motorcycles, covering Electra Glide and Road King family variants including standard, classic, police, and Ultra Classic trims. Compatibility centers on matching the original part number and harness connections. If your bike originally used 74505-02, this replacement is intended as the direct substitute.

• Electra Glide models: FLHT, FLHTC, FLHTCI, FLHTPI (2002–2003)
• Road King models: FLHR, FLHRI, FLHPI, FLHRCI (2002–2003)
• Road Glide and Ultra Classic fits: FLTRI, FLHTCUI (2002–2003)
• Always verify the part number on your original regulator before purchase

How does this regulator-rectifier affect charging and electrical reliability?

This unit converts the alternator's alternating current into usable direct current and moderates voltage to safe levels for the battery and electronics. A functioning regulator-rectifier reduces risk of overcharging and prevents dim or fluctuating lights caused by inconsistent output. It won’t fix unrelated wiring faults, so confirm overall electrical health during diagnosis.

• Converts AC from stator to regulated DC to charge the battery
• Helps prevent battery over-voltage and component stress
• Smoother, steadier headlight and accessory illumination
• Replace only after checking connectors and harness condition

What should I check before buying and installing the OLIFANT 74505-02?

Prior to purchase, inspect your motorcycle’s current regulator for the stamped or printed part number and compare connector types and mounting points. Check the stator and battery condition since a bad stator or damaged wiring can mimic regulator failure. If you’re unsure, have a mechanic test charging voltage at idle and while revving.

• Match OEM part number 74505-02 and connector configuration
• Test charging voltage and stator output with a multimeter
• Inspect harness, fuses, and ground connections for corrosion or damage
• Consider professional installation if you’re not experienced with motorcycle electrics

What are the practical benefits of installing this replacement part?

Installing a correctly matched regulator-rectifier restores the charging system’s ability to maintain battery health and deliver stable power to lights and accessories. Riders will typically notice steadier electrical performance and reduced risk of battery drain or electrical component stress. It’s a cost-effective preventative step when electrical symptoms first appear.

• Restores reliable charging and improves battery longevity
• Stabilizes lighting and accessory performance during rides
• Direct-fit design minimizes wiring changes and installation time
• Replacement part number aligns with original equipment specifications

Who is this for: The OLIFANT 74505-02 regulator-rectifier is for owners and technicians maintaining 2002–2003 Harley-Davidson Electra Glide, Road King, Road Glide, and Ultra Classic models who need a compatible direct-replacement charging module. Choose this product if your bike shows charging irregularities and the original part number matches 74505-02 — and if you want a straightforward swap that restores regulated DC output without custom wiring.
