Voltage Regulator Rectifier For Polaris Ranger 500 RZR 800 EFI 4012748

Voltage Regulator Rectifier for Polaris Ranger 500 RZR 800 EFI

This voltage regulator rectifier for Polaris replaces OEM 4012748 and keeps your charging system stable by converting stator AC output to regulated DC for the battery and electrical accessories.

Overview

This voltage regulator rectifier for Polaris is a direct-fit charging component for Ranger 500, RZR 800, and EFI models. The voltage regulator rectifier for Polaris manages current from the stator so the battery stays charged and lights, gauges, and fuel injection receive steady voltage. It suits riders replacing a failed regulator or servicing a machine before the season starts.

Specs At A Glance

Good To Know

Q: How do I know my regulator rectifier failed? A: Common signs include a battery that will not hold charge, dimming lights, or a machine that dies after jump-starting. Testing stator output and regulator voltage with a multimeter confirms the fault.

Q: Does this fit EFI and carbureted machines? A: This unit is listed for the EFI applications named in the title. Verify your model, year, and factory part number 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.
