Specs At A Glance

Good To Know

Q: How do I know if my ignition module has failed? A: Common signs include no spark, erratic firing, or an engine that cuts out once warm. Testing the stator and coil first helps confirm the module is the faulty part.

Q: Does this module need any programming after install? A: No, this is a plug-and-play replacement for the original unit. It connects to the factory harness without additional calibration.

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