Voltage Regulator Rectifier RM30Y14 for Polaris Sportsman and Ranger

Polaris Sportsman 600 and 700, Ranger 425 and 500, 2004 model year

This is a brand new voltage regulator rectifier, part number RM30Y14, built as a direct replacement for the original unit fitted to the Polaris Sportsman 600 and Sportsman 700, and the Polaris Ranger 425 and Ranger 500, in the 2004 model year. It is plug-and-play and a direct fit, so no assembly is required before installation. The unit is built with a higher grade of electrical components than the original part and the quality exceeds the OEM equipment it replaces. Every unit is tested before it is shipped.

The regulator uses five plugs with five pins in total and staggered lead lengths of 160 mm, 140 mm, 125 mm and 115 mm. It delivers a minimum charging voltage of 14.5 V plus or minus 0.5 V, handles up to 25 A / 300 W of charging current, holds open circuit voltage below 15 V and works from -20 C to 85 C. Wiring is straightforward: the red wire is the battery positive output, the brown wire is the battery negative or ground output, and the yellow wires - with any stripe - are the stator AC input and are interchangeable, with no polarity to observe. Please note that Polaris fitted more than one regulator to 2004 machines; this RM30Y14 is the unit that replaces OEM part numbers 4010929 and 2204317, so check your original part before ordering. Before fitting, check the AC output of the stator, replace any burned or corroded connectors, check and repair melted wiring, and use hi-temp dielectric grease on all connectors. Battery condition is critical - always fully charge the battery before carrying out any charging system tests. Risk of electric shock: disconnect the battery before servicing.
