Stator for Yamaha YFM 350 Wolverine 1995-1999
Yamaha YFM 350 Wolverine, 1995-1999 - RMSTATOR reference RM01377
Brand new aftermarket stator for the Yamaha YFM 350 Wolverine, built as a direct replacement to your original unit. It is plug-and-play, a direct fit and an easy installation - the 35 mm by 93 mm by 16 mm core sits in the original position and the eight-wire harness ends in the original two plugs, so no cutting, splicing or re-pinning is needed.
The unit uses the highest grade lamination materials and copper windings rated to 200 degrees Celsius, with the pick-up coil integrated. A second set of connectors is supplied as well as the stator side: on machines of this age the harness-side connectors are often melted, corroded or defective, and they are a major cause of repeat electrical faults. All units are tested before shipment. This part carries the reference RM01377 and cross-references Yamaha OEM part number 4KB-85510-00-00.

Frequently Asked Questions
Will it fit without modification?
Yes. It is a direct replacement to your original unit on the YFM 350 Wolverine, with the original core size, the original grommet position and the original two-plug, eight-pin harness, so it is plug-and-play with no wiring changes.
What is included?
The stator assembly with its pick-up coil, two sets of connectors, and the rubber grommet. All units are tested before shipment.
Why are two sets of connectors supplied?
Because the harness-side half of the connector on machines of this age is very often melted, corroded or otherwise defective, and that is a major cause of repetitive electrical issues. Replacing both halves at the same time removes the fault path rather than plugging a brand new stator into a damaged socket.
How do I tell whether my old stator has failed?
Typical signs are a battery that will not hold charge, dim or flickering lights, weak or intermittent spark and no rise in charging voltage with engine speed. Measured cold, the alternator windings should read 0.4 ohms +/-20%, the pickup 450 ohms +/-20% and the source coil 330 ohms +/-20%. An open circuit, a dead short or continuity between any winding and the stator body confirms the unit has failed.
