Mosfet Voltage Regulator for Polaris Ranger, RZR and Sportsman
Polaris Ranger 500 and 700, RZR 800, Sportsman 500, 700 and 800 - 2007 to 2010 - RMSTATOR RM30336
This is an advanced MOSFET voltage rectifier regulator for the Polaris Ranger 500 and 700, RZR 800 and Sportsman 500, 700 and 800 built between 2007 and 2010. It is supplied under RMSTATOR part number RM30336 and is a direct replacement for the OEM unit, cross referencing to Polaris 4011925, 4012384 and 4011569. Installation is plug and play, so it goes straight into the original mounting position and connects to the standard harness.
The important difference here is the MOSFET design. Traditional diode style regulators shed excess charging output as heat, which is why so many of them cook themselves to death on hard working utility machines. A MOSFET unit switches rather than burns off that energy, so it runs considerably cooler, delivers power more efficiently and puts less parasitic load on the engine. It also carries overheat protection: if it does get too hot it shuts down temporarily and recovers, instead of burning out permanently. The practical results are cooler running, better fuel efficiency, longer battery life and optimised power delivery compared with a traditional diode style regulator. Dispatched from the UK.

Frequently Asked Questions
What is the advantage of a MOSFET regulator over the standard one?
A traditional diode style regulator disposes of surplus charging output as heat, and that heat is what eventually destroys it. A MOSFET unit switches the excess instead, so it runs at cooler temperatures, delivers power more efficiently, is easier on the battery and puts less drag on the engine. This unit also has overheat protection, so in extreme conditions it shuts down temporarily and then recovers rather than failing permanently.
Will it fit without modification?
Yes. It is a direct replacement for the OEM unit with plug and play installation, using the same three plug, eight pin arrangement. Check the number on your existing regulator against 4011925, 4012384 or 4011569 before ordering, as Polaris used more than one regulator across this range.
What is included?
The MOSFET voltage regulator rectifier itself, with three plugs and eight wires at 90 mm and 145 mm, ready to connect to the standard harness. No additional hardware is listed for this item, so retain the original mounting bolts.
How do I know my original regulator has failed?
Measure the charging voltage at the battery with the engine running. It should sit around 14.5 V +/- 0.5 V. Anything stuck at resting battery voltage means it has stopped charging; anything well above 15 V means it has stopped regulating. On these Polaris machines the other tell tale is a regulator body that is far too hot to touch after a working session, along with batteries that go flat repeatedly.
