Compatible Models
We do our best to list all compatible models. Although this may be the part you need, your exact model may not appear below.
Compatible equipment / model
- Polaris Sportsman 570 — 2014-2020 compatible applications with 19 mm stator and matching connectors
Product Overview
A Sportsman that repeatedly drains the battery, loses charging voltage when hot, or overcharges may have problems in both the stator and regulator. This paired kit is useful when testing confirms charging-system failure or when heat damage makes replacing both components sensible.
The verified stator design applies to engines built after the specified production change and uses a 19 mm stator. Measure and match the original before installation.
Key Features & Performance
- Generator stator and MOSFET regulator/rectifier
- Paired charging-system repair
- MOSFET-style voltage control
- Aftermarket kit for compatible Sportsman 570 applications

Frequently Asked Questions
Q: Why replace the stator and regulator together? A: A failed or overheating component can stress the other, but both should be tested.
Q: Does the 19 mm measurement matter? A: Yes. The kit is tied to the matching stator design.
Q: Can a bad battery damage charging parts? A: A failed battery or poor connection can overload or confuse diagnosis.
Q: What voltage should I see? A: Use the Polaris service specification and test at the prescribed engine speed.
