2-Position Ignition Key Switch for Yamaha ATVs
Yamaha Big Bear, Warrior, Wolverine, Kodiak, Grizzly and Banshee 250, 350, 400 and 600, 1993-2008 - Part Number RM05001
A brand new aftermarket two position ignition key switch for Yamaha ATVs built between 1993 and 2008, covering the Big Bear, Warrior, Wolverine, Kodiak, Grizzly and Banshee in 250, 350, 400 and 600 cc form. It is a direct replacement to your original unit - plug-and-play, direct fit and easy to install, with a 35 mm barrel that drops into the existing panel cut-out.
The switch works in two positions, off and on, and carries four wires through a single plug. Two keys are supplied cut to the new barrel and the mating connector is included, so a plug that has gone brittle or green on the machine side can be renewed at the same time. Yamaha listed a long run of superseded numbers for this switch across the model range - all of them are set out in the cross reference table below, so the number stamped on your original unit will confirm the fit. All products shipped are tested.

Frequently Asked Questions
Does it fit without modification?
Yes. It is a direct replacement to your original unit - plug-and-play, direct fit, easy installation. The 35 mm barrel and 50 mm body match the original, and the four wires run to a single plug that connects to the existing loom.
What comes in the box?
The ignition key switch, two keys and a connector. Every unit is tested before it is shipped.
How do I know my old switch has failed?
The usual signs are an engine that dies over rough ground, an ignition that only makes contact when the key is jiggled, or a machine that is completely dead with a known good battery. Checking continuity across the switch terminals in the on position will confirm it - intermittent or absent continuity means the contacts inside have corroded or burnt.
My original carries a different Yamaha number - will it still fit?
Very likely. Yamaha superseded this switch several times across the range and nine of those numbers are listed in the cross reference table above. If the number stamped on your original appears there, this is the correct part.
