The flywheel generates electricity through the rotation of its magnets around the stator, inducing current in the copper coils. This energy is used to power the ignition system, allowing the high-voltage coil to generate the spark at the spark plug, necessary for engine combustion. Make sure the wires running from the flywheel to the regulator and other electrical components are in good condition, free of wear and tear or sulfation. The flywheel is the power source that makes everything work.
