Specs At A Glance

Good To Know

Q: Does this exciter coil need any modification to install? A: No, it mounts in the stock stator location and uses the factory wiring connection. Confirm your engine's stator plate matches the 21049-3007 layout before ordering.

Q: How do I know my exciter coil needs replacing? A: Weak or no spark, hard starting, and misfires under load are common signs of a failed exciter coil on a JS 550. Testing the coil with a multimeter against factory resistance specs confirms the fault.

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