OLIFANT Voltage Regulator Rectifier for Harley Touring 2009–2014 - 38A, 14.7V Stable Charge

OLIFANT Voltage Regulator Rectifier is a direct-fit electrical replacement that stabilizes charging voltage for Harley-Davidson 2009–2014 twin-coach models.

This replacement regulator-rectifier is engineered to restore and maintain proper charging system performance on a range of Harley-Davidson touring motorcycles. Designed to match the original equipment fit and electrical characteristics, it converts alternator AC to stable DC while regulating output around a 14.7V set point. The unit supports negative polarity systems and delivers up to 38 amps, making it suitable for stock and commonly accessorized rigs.

Will this OLIFANT unit fit my Harley Touring model?

Yes — the part is made to replace factory regulator-rectifiers used on many Harley touring bikes from the listed years. Confirm compatibility by cross-referencing the part numbers and your bike year/model before purchase.

• Fits Electra Glide models 2009–2014
• Fits Street Glide and Road Glide 2009–2014 (Road Glide listed through 2013)
• Compatible with Road King, Tri Glide, Ultra and select CVO 2009–2014
• OE part numbers referenced: 7450509, 74505-09A, 7450509A

How does the regulator-rectifier protect my motorcycle's electrical system?

The device performs two functions: rectifying alternator AC into DC and regulating voltage to prevent over- or under-charging the battery. Maintaining the set point around 14.7 volts helps protect electronics, battery life, and lighting systems without altering stock electrical behavior.

• Rectifies three-phase alternator output into DC power
• Regulates output at approximately 14.7V to avoid voltage spikes
• Rated at 38 amps to support charging plus accessories
• Built for negative-ground electrical systems typical on these Harleys

What are the key specifications and installation considerations?

The OLIFANT unit follows the original polarity and voltage specifications so it installs in place of the factory part with the same wiring orientation. Installation generally requires basic hand tools and secure mounting to a grounded surface; torque and connector cleanliness matter for consistent performance.

• Voltage: 12V system, set point ~14.7V
• Polarity: negative-ground system compatibility
• Current rating: 38 amps continuous
• Direct-fit: designed to replace OE part numbers listed above

How long should I expect this part to last and how can I maximize lifespan?

Lifetime depends on riding conditions, heat exposure, and electrical load. Proper mounting for airflow, clean connectors, and avoiding excessive aftermarket accessory load will extend service life and keep charging stable.

• Mount where OEM unit sits to ensure adequate cooling
• Keep connectors dry and corrosion-free with dielectric grease
• Verify battery health; a weak battery stresses the regulator
• Limit accessory draw within the 38 amp rating or add a secondary power source

Who is this for? If you own a Harley-Davidson touring motorcycle from 2009–2014 (including Electra Glide, Street Glide, Road Glide, Road King, Tri Glide, Ultra or CVO variants) and you need a reliable charging system replacement that meets OE form and function, this OLIFANT regulator-rectifier is tailored for that purpose. It's aimed at riders who want a direct-fit, specification-matching replacement that supports typical touring electrical loads and maintains stable battery charging without modification.
