OLIFANT Voltage Regulator Rectifier for Arctic Cat 400/500/375 (2000–2009) — OEM Direct-Fit, Heat-Dissipating

OLIFANT Voltage Regulator Rectifier replaces the factory unit to stabilize charging and protect the electrical system on compatible Arctic Cat 400, 500 and 375 ATVs from model years 2000–2009.

If your Arctic Cat is experiencing dimming lights, battery overcharge, or intermittent electrical problems, a failing regulator/rectifier is often the cause. This aftermarket OLIFANT unit is built as an OEM direct-fit replacement for multiple Arctic Cat models and model years, offering the same connector layout and mounting points for straightforward installation. It corrects alternator output by converting AC to DC and regulating voltage to safe levels for the battery and accessories.
