This stator is constructed to provide the ignition system with a stable electrical source during starting, acceleration, idle operation, and sustained running. This style of stator is also associated with a 12-amp charging configuration, so clean electrical output and connector integrity are especially important. 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.
• High-temperature insulation helps protect the windings from heat cycling inside the engine cowling.
• Precision-wound copper coils are used to promote efficient voltage generation and stable output.
• Marine-grade lead wires and molded connectors help maintain dependable contact in a high-vibration environment.

Key Functional Details

• Helps the ignition system recover from weak output, hard starting, and cylinder drop-out symptoms.
• Supports dependable starting by delivering the voltage needed by the ignition module.
• Helps correct intermittent spark loss caused by heat-sensitive stator windings.
• Supports smooth acceleration by helping the ignition system maintain consistent energy.

Problems a Weak Stator Can Cause

• Unstable ignition output
• Weak or intermittent spark
• Random cylinder drop-out
• No-start conditions
• High-rpm breakup

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