Voltage Regulator Rectifier for Kodiak 400 450 YFM400

This voltage regulator rectifier for Kodiak 400 and 450 fits YFM400 2X4 and 4X4 models from 2000 through 2006, regulating stator output so the battery charges and the lights stay steady.

Overview

This voltage regulator rectifier is a replacement charging component for the Kodiak 400 and 450 lineup, including YFM400 2X4 and 4X4 machines. It turns AC voltage from the stator into regulated DC power that the battery and electrical accessories can use. Owners fit this regulator rectifier when charging stops or voltage runs out of spec.

Specs At A Glance

Good To Know

Q: What symptoms mean the regulator rectifier needs replacing? A: A battery that will not stay charged, bulbs burning out, or voltage readings that swing too high or too low all point to a bad regulator rectifier. Check stator output first to rule it out.

Q: Does this fit both 2X4 and 4X4 Kodiak models? A: It is listed for YFM400 and YFM450 Kodiak machines in both drive configurations for the stated years. Confirm your model and year against the fitment list before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
