Specs At A Glance

Good To Know

Q: How do I know if my regulator has failed? A: Common signs are a battery that will not hold charge, flickering or dim lights, and a battery that gets hot or boils. Testing charging voltage at the battery with the engine running is the quickest way to confirm.

Q: Does this replace the stock unit directly? A: It is built to fit the listed Polaris models and match the 4012192 reference, using the same connector and mounting points. Confirm your machine's 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.
