Good To Know

Q: How do I know the stator needs replacing? A: Common signs include a battery that will not hold a charge, dim or flickering gauges, and weak or no spark. Testing charging output with a multimeter confirms whether the stator is the cause.

Q: Does this stator require any modification to install? A: It is built as a direct replacement for the OEM unit, so it mounts in the factory location and connects to the original wiring. Check your machine's serial number and existing part number before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
