Electronic Magneto Ignition System
The 4 and 5 kW generator sets are equipped with a
dependable
electronic
(Figure 3-6) containing the following:
D A magnet assembly which is PERMANENTLY
affixed to the flywheel.
D An electronic magneto ignition module, which is
mounted to the #1 side cylinder barrel.
D A controller which stops the engine by grounding
the ignition module.

Figure 3-6. Electronic Magneto Ignition System
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.
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 plugs,
igniting the fuel-air mixture in the combustion chambers.
Other than periodically checking/replacing the spark
plugs, no maintenance, timing, or adjustments are
necessary with this ignition system.
