Electrical System and Components
Electronic Magneto Ignition System, CH11-15 Engines
These engines are equipped with a dependable
electronic magneto ignition system. The system
consists of the following components:
• A magnet assembly which is permanently
affixed to the flywheel.
• An electronic magneto ignition module which
mounts on the engine crankcase.
• A kill switch (or key switch) which grounds the
module to stop the engine.
• A spark plug.

Operation
As the flywheel rotates and the magnet assembly
moves past the ignition module, a low voltage is
induced in the primary windings of the module.
When the primary voltage is precisely at its peak, the
module induces a high voltage in its secondary
windings. This high voltage creates a spark at the tip
of the spark plug. This spark ignites the fuel-air
mixture in the combustion chamber.
The timing of the spark is automatically controlled by
the module. Therefore, other than periodically
checking/replacing the spark plug, no maintenance,
timing, or adjustments are necessary or possible with
this system.
In the event starting problems should occur which
are not corrected by replacing the spark plug, refer to
the following Troubleshooting Guide for trouble
analysis procedures.
