How does this regulator rectifier improve charging and electrical stability?

The regulator rectifier converts generator AC to regulated DC and prevents overcharging or undercharging of your ATV battery. Replacing a worn unit restores consistent voltage to lights, ignition and accessories, reducing electrical faults and extending battery life.

• Converts stator AC to stable DC for reliable battery charging
• Maintains correct system voltage under variable RPMs
• Prevents voltage spikes that can damage electrical components

Is installation complicated and what connector does it use?

Installation is straightforward for anyone comfortable with basic ATV wiring and bolt-on parts. The OLIFANT regulator rectifier arrives with the compatible 4-wire plug (4 wires/plugs) to mate with the factory harness—no cutting required on correctly equipped models.

• Direct-fit replacement matching original plug pattern
• Mounts using existing bracket points on compatible Polaris models
• Recommended: confirm connector type and OEM ref numbers 2203636 or 4060173 before purchase

What should I check before buying or fitting this part?

Verify your ATV’s year, model and whether the original regulator used a four-wire plug. Compare the OEM reference numbers to ensure compatibility and inspect your stator and wiring for damage—replacing a regulator while the stator is faulty will not fully resolve charging issues.

• Confirm vehicle year and model against the fitment list above
• Match OEM reference numbers: 2203636 and 4060173
• Inspect stator and harness for corrosion or broken wires before final installation

Who is this for: This OLIFANT Voltage Regulator Rectifier is intended for owners, mechanics and restoration specialists working on late‑1990s to early‑2000s Polaris 500-series ATVs and utility machines who need a reliable, direct-fit replacement. It’s ideal when you observe charging irregularities, battery drain after rides, flickering lights, or inconsistent electrical performance and you want a part that matches factory wiring and OEM reference numbers for a quick swap.
