Voltage Regulator Rectifier for Yamaha YFM 350 Warrior and Wolverine
Yamaha YFM 350 Warrior and Wolverine YFM350, 2002-2005 - Part Number RM30315
A brand new voltage regulator rectifier for the Yamaha YFM 350 Warrior and the Wolverine YFM350 built between 2002 and 2005. It is a direct replacement for the original unit: the single five-pin plug, the 50 mm wire tails and the 67 mm centre to centre mounting holes all match the factory part, so it is plug-and-play, a direct fit, and easy to install with no assembly required.
The regulator is the component that turns the stator's alternating current into direct current and holds the charging voltage at a safe level for the battery. This unit is built with a higher grade of electric components than the original, with an improved heat sink and improved charging capabilities, so the quality exceeds the OEM equipment. Heat is what kills a regulator on these machines, so the larger finned body matters in service. All products shipped are tested.

Frequently Asked Questions
Will it fit without modification?
Yes. It is a direct replacement to your original unit - plug-and-play, direct fit, easy installation, with no assembly required. The single plug carries five pins and five wires, and the mounting holes are 67 mm centre to centre, exactly as on the original.
What do I receive?
One brand new voltage regulator rectifier with a 50 mm wire tail and the five-pin plug already fitted. Every unit is tested before it is shipped.
How can I tell the old regulator has failed?
With the engine running, the charging voltage at the battery should settle at about 14.5 V. A battery that will not hold charge, lights that surge with revs, or a battery that gases and boils because voltage is running away above 15 V are the usual signs. A regulator body that is scorched or too hot to touch after a short ride is another.
Does it fit both the Warrior and the Wolverine?
Yes, for the 2002 to 2005 model years. Both machines use the same regulator rectifier, listed by Yamaha as 4KB-81960-10-00. Check that number on your original unit before ordering.
