Mosfet Regulator for Polaris RZR 900/1000 | Ranger 570/1000 | Sportsman | ACE | General 2012-2021 OEM# 4015231 | 4015215

CAD$ 214.00
Availability: In stock

Important notice: This product is a relocation kit to Polaris Recall Z-16-01-C (OEM # 2206620, 2206367, 2206473). We strongly recommend changing the location of the regulator to avoid it to overcharge due to dust, mud and rocks. If you need the regulator only please purchase the part number RMS021-107099.

Battery condition is important. No regulator can make up for a bad or weak battery. If in doubt charge your battery and have it load tested, or simply replace it. ALWAYS START WITH A FULLY CHARGED BATTERY !

RZR Regulator Relocation Instructions

Step 1:

Remove original and mounting bracket from driver side rear wheel well area. Bracket is mounted to body with 10mm nut/bolts, accessible from inside the cab and underneath. Remove regulator from bracket with 10mm nut/bolts. We suggest reusing the bracket for your new regulator mount.

Step 2:

Separate Red & Black battery connections, made at starter solenoid and chassis bolt. 2-wire sealed and locking connector version not shown. Unplug just like Stator connector above. Remove rear seats on 4-seat models. Remove rear access hatch. Unplug regulator’s stator and battery connections. Stator connector is the 3-wire sealed and locking connector. Depending on which regulator you have, the battery connection is either Black & Red wires with ring terminals, or a 2-wire sealed and locking connector. Separate Black & Red wires with ring terminals: Black wire is battery -, grounded to a chassis bolt. Red wire is battery +, connected to the starter solenoid. 2-wire sealed and locking connector with Black & Red wires: Unplug connector.

Step 3:

Plug in regulator relocation harness, similar to previous step.

Step 4:

Remove shifter tunnel housing that covers front driveshaft for access. Route relocation harness along driveshaft tunnel towards front of vehicle, using wire ties to secure along the way.

Step 5:

Reusing original regulator mounting bracket, mount new regulator in front underhood area. Keep regulator as high as possible, away from heat-generating sources, and away from tires and potential mud, water and debris. In these pictures we’ve reused 2 empty holes located in the firewall on the drivers side that are spaced perfectly for the mounting bracket. We have reused the original mounting bracket hardware. Plug in the relocation harness to the regulator. The connectors are Black and Grey, color-coded to their connections on the regulator. Make sure to push in connectors until the locking tab clicks into place to secure the connection.

Step 6:

Reinstall driveshaft tunnel, rear access hatch, and seats. You are ready to ride!

RMSTATOR renowned MOSFET voltage regulation design
Significantly decreases internal operating temperature with highly efficient MOSFET transistor regulation circuit. This technology runs much cooler than the OEM silicon rectifier regulation circuit and requires much less power to operate.

Automotive grade wiring harness with OEM-quality heavy-duty connectors
Made with the same Delphi connectors as OEM Polaris parts, our wiring harnesses are manufactured in a factory with controlled quality processes. They use the same Cross-Link braided copper wire as the OEM parts, and resist heat, oil, acid, gas and more with very low electrical resistance.

Plug & Ride design
Our voltage regulator housings are manufactured to OEM specifications for a fast and easy installation.

All item pictures are accurate, if in doubt, do not hesitate and compare our item to your original part.

WARNING : This product is suitable for certain 2016-2017 models whose regulator connects directly to the main harness of the vehicle without conversion harness.

If you own a 2016 RZR 1000 or any other RZR from a year prior to 2016, you must use a conversion harness to install this regulator.
