RM30N03 Voltage Regulator Rectifier
Polaris Magnum, Sportsman, Xplorer, Xpress and Big Boss 400 / 425 / 500 - 1994-1999
The RM30N03 is a brand new aftermarket voltage regulator rectifier supplied as a direct replacement for the original Polaris unit fitted to the Magnum, Sportsman, Xplorer, Xpress and Big Boss in 400, 425 and 500 cc form between 1994 and 1999. It is plug-and-play and a direct fit, so installation is easy and there is no assembly required - the five individual plugs connect straight into the existing loom.
A higher grade of electrical components is used throughout, together with an improved heat sink and better charging capability, so the quality exceeds the OEM equipment it replaces. Every product shipped is tested before dispatch. The RM30N03 is rated to a generous 50 A / 500 W maximum charging current with a minimum charging voltage of 14.5 V plus or minus 0.5 V, and its five leads are cut to the original lengths of 190, 180, 165, 145 and 140 mm so the unit sits and routes exactly as the factory part did.

Frequently Asked Questions
Does this fit without modification?
Yes. The RM30N03 is a direct fit, plug-and-play replacement for the original unit on the listed Polaris models. No assembly is needed, and because each of the five wires carries its own plug there is nothing to cut, splice or solder - you simply unplug the old regulator and connect the new one.
What is included?
One RM30N03 voltage regulator rectifier with its five wires and five plugs already fitted, in lengths of 190, 180, 165, 145 and 140 mm. Each unit is tested before it is shipped and arrives ready to install.
How do I tell my old regulator rectifier has failed?
Typical warning signs are a battery that keeps going flat or will not hold charge, charging voltage at the battery that never reaches around 14.5 V, an over-charged battery that boils or swells, lights that dim or flicker as engine speed changes, and a regulator body that becomes too hot to touch. Burnt, melted or corroded plug terminals point to the same fault.
How do I confirm this is the right unit for my quad?
Check the number moulded or printed on your existing regulator against the Polaris references 4060133, 4060113 and 2205046, and confirm the physical match: a 75 by 90 by 17 mm body with five separate plugs. If your machine falls outside 1994 to 1999, use the part number to verify before ordering.
