OLIFANT Voltage Regulator Rectifier for Arctic Cat 400/500/375 (2000–2009) — OEM-fit 7-wire, 3+4‑pin

OLIFANT's Voltage Regulator Rectifier is a direct-fit electrical replacement for Arctic Cat 400, 500 and 375 ATV models (2000–2009) that stabilizes charging output and plugs into OEM connectors for straightforward installation.

If your ATV's battery is overcharging, undercharging, or your lights are flickering, this replacement regulator rectifier restores proper voltage control so the electrical system runs reliably. Built to match the factory connectors and wiring layout, it replaces aging or failed units on a range of Arctic Cat models without major modifications. The unit is intended for routine mechanical replacement and electrical repair—no performance promises, only correct fitment and electrical regulation support.

Which Arctic Cat models does this regulator rectifier fit?

This OLIFANT unit supports multiple Arctic Cat ATVs across model years and trim levels. It lists compatibility explicitly for common 400 and 500 series machines plus a 375 model, covering both two- and four-wheel variants where applicable.

• Arctic Cat 400: 2001–2008; includes TRV 400 (2006–2008), TBX 400 (2004–2006), DVX 400 (2004–2008)
• Arctic Cat 500: 2000–2009; includes TRV 500 (2003–2008), TBX 500 (2002–2006)
• Arctic Cat 375: 2x4 and 4x4, model year 2002
• Reference numbers: 3402-682, 3530-028, 3530-059 for cross-checking fit

How does installation work—will it fit my ATV without changes?

The part is designed as an OEM direct fit, using the same plugs and wire count as the original. You can expect a plug-and-play swap in most cases, but basic electrical safety and connector checks are recommended before finalizing the installation.

• Connector configuration: 3-pin plug plus 4-pin plug
• Wiring: 7 wires total to match factory harness routing
• Mounting: uses original mounting points—no drilling or splicing typically required

What performance or electrical behaviors should I expect after replacement?

Replacing a worn regulator rectifier should normalize charging voltage and reduce symptoms such as battery drainage, dim or erratic lights, and intermittent electrical faults. It manages voltage coming from the stator to the battery and electrical system without altering engine performance.

• Stabilizes charging voltage to the battery and accessories
• Helps prevent overvoltage spikes that can damage electronics
• Reduces flickering lights and inconsistent electrical readings

What should I verify before buying this replacement part?

Confirm your ATV's model year and original regulator reference numbers, and inspect the connector type on your harness. Matching the 3-pin plus 4-pin plug layout and verifying one of the listed reference numbers ensures you receive the correct unit for a trouble-free swap.

• Check your OEM reference: 3402-682, 3530-028, or 3530-059
• Confirm plug arrangement on your vehicle: 3-pin + 4-pin with 7 wires
• Compare mounting points and physical dimensions to your existing unit

Who is this for: Owners and technicians working on Arctic Cat ATVs from the early 2000s who need a reliable, direct-fit replacement regulator rectifier. It's aimed at riders troubleshooting charging system issues or performing routine electrical maintenance—mechanical skill for safe electrical disconnection and reconnection is required. If you value OEM-style fitment and straightforward installation, this OLIFANT regulator rectifier provides a compatible option for restoring proper electrical regulation on supported Arctic Cat models.
