MOSFET Voltage Regulator Rectifier for Polaris Sportsman 450 HO / 550 / 570 X2 / 850 XP / 1000 2010-2020 | OEM# 4012678
MOSFET Voltage Regulator Rectifier for Polaris Sportsman 450 HO / 550 / 570 X2 / 850 XP / 1000 2010-2020 | OEM# 4012678
When using this regulator on 2016-2018 Polaris Sportsman 570 models, please pay close attention to the stator and regulator wiring harness routing. The OEM wire routing was very poor, and allowed the harness to rub against the motor, damaging the insulation and damaging the charging system. We recommend routing your stator/regulator wiring outside of the frame rail, and securing the harness to the frame with zip ties. This should prevent any future damage to the wiring harness.
Battery condition is extremely important. No voltage regulator can work correctly with a bad or weak battery. Always fully charge your battery before performing any charging system tests or replacing parts. If there is any doubt, have the battery load tested or replaced.

Brand new Mosfet voltage rectifier regulator
STOP BURNING YOUR REGULATOR RECTIFIER !
It is time to update or replace your voltage regulator with the advanced MOSFET type.
It runs cooler than all OEM diode style regulators. In addition, this rectifier has overheat protection, rather than burn up it will simply turn off for a while and cool off.
- Direct replacement to your original unit
- Plug-and-play, direct fit, easy installation
- The quality exceeds the OEM equipment
- Improved heat sink and charging capabilities
- Higher grade of electric components
- All shipped products are tested
All item pictures are accurate, if in doubt, do not hesitate and compare our item to your original part.
Why use Mosfet Enhanced technology?


Runs cooler
Runs much cooler than the traditional Shunt voltage regulator rectifier.

Saves gas
Less load on the stator, less work, less fuel is used and you save.

Regulated energy
The power charging your battery is steadier and smooth.

Extended battery life
Extends the battery’s life and cold cranking capacity.

More engine power
Removes stator load resulting in more engine power.

Optimized power
Optimize power delivery by switching the stator coils on or off.
