🔌 Function

The stator produces ignition charge voltage and alternator output beneath the flywheel. It supplies the ignition system and charging circuit with the electrical energy required during engine operation.

⚠️ Common Signs of Failure

• Weak or missing spark
• Battery not charging
• Engine misfire under load
• Spark loss after engine warms up
• Low or unstable charging voltage
• Tachometer signal issues
• Burnt windings or damaged stator leads
• Low high-speed or low-speed stator output during testing
