The stator acts as the electrical foundation of the ignition system, producing the current needed to feed the ignition module and support consistent firing. The design priorities are especially important on Johnson/Evinrude applications where ignition stability depends on clean stator output.

Stator Design

• Laminated core sections help concentrate magnetic flux from the flywheel magnets for reliable electrical production.
• Marine-grade lead wires and molded connectors help maintain dependable contact in a high-vibration environment.
• Precision-wound copper coils are used to promote efficient voltage generation and stable output.
• Epoxy encapsulation helps shield internal windings from moisture, vibration, and corrosion.

Key Functional Details

• Helps correct intermittent spark loss caused by heat-sensitive stator windings.
• Supports dependable starting by delivering the voltage needed by the ignition module.
• Designed for use in wet, hot, and vibration-heavy marine engine compartments.
• Helps reduce high-RPM breakup caused by weak or unstable stator output.

Failure Symptoms to Check

• Charging output problems where the stator also supports charging circuits
• Unstable ignition output
• Engine misfire under load
• Hard starting
• Random cylinder drop-out

For best results, stator output should be verified with the proper service-manual resistance and DVA voltage tests before installation.
