Stator for Polaris 500 ATV and Utility Models
Polaris Big Boss, Magnum, Ranger, Scrambler, Sportsman and Worker 500 - 1997-2001
This is a brand new stator for the Polaris 500 range of the late 1990s, covering the Big Boss, Magnum, Ranger, Scrambler, Sportsman and Worker. It is a direct replacement for the original unit and fits plug and play, with no rewiring or modification. The stator carries the alternator windings that charge the battery, the pick-up coil that triggers the ignition, and the two source coils that feed the CDI, so a fault in any one of them can leave the machine dead.
The windings are the highest grade of copper, rated to resist 200 degrees Celsius, on the highest grade of lamination material. The unit is 114 mm across the outside, 51 mm inside and 20 mm thick, with nine wires and ten pins. The pick-up pulsar coil, the connector and the rubber grommet are supplied fitted. Every published resistance figure is listed in the table below, so you can test your original with a multimeter before ordering. Every unit is tested before it is shipped.

Frequently Asked Questions
Will this fit without modification?
Yes. It is a plug and play direct replacement for the original stator on the listed Polaris 500 models, using the original mounting and the original connectors. Check that your existing unit carries Polaris part number 3085561 or 3086821 before ordering.
What is included?
You receive the stator with the pick-up pulsar coil, the connector and the rubber grommet fitted. The flywheel, the cover gasket and the CDI are not included.
How do I know my stator has failed?
Test each circuit in turn with a multimeter. The alternator winding should read 0.6 ohms plus or minus 20 per cent from yellow to yellow/red, the pick-up 100 ohms plus or minus 20 per cent from white to white/red, the first source coil 450 ohms plus or minus 20 per cent from green to red/black, and the second source coil 3.8 ohms plus or minus 20 per cent from green to black. Any open circuit, any short to earth, or a reading well outside those bands means the stator has failed.
The bike charges but will not start - could it still be the stator?
It can be. This stator carries four separate circuits and they fail independently. A good alternator winding will keep the battery charged while a failed pick-up or source coil leaves the CDI without a trigger or without power, so the engine cranks but never fires. Test all four circuits before condemning the CDI.
