Flywheel Magneto Ignition System

An AC ignition system using a generating coil (commonly called a source coil or exciter coil) and either a pickup coil (used in a Capacitor Discharge Ignition) or contact points (used in an Energy Transfer Ignition) as well as a magnetic flywheel to provide primary ignition current and switching. An external ignition coil is used to step up the voltage in order to produce a spark at the sparkplug.
