Electrical System
Fixed Ignition System
This system uses a capacitive discharge (CD) coil. Ignition timing and spark remains constant regardless of engine
speed. Timing of spark is controlled by location of fl ywheel magnet group as referenced to engine TDC. A typical fi xed
ignition system consists of:
● 1 magnet assembly which is permanently affi xed to fl ywheel.
● 2 electronic capacitive-discharge ignition modules which mount on engine crankcase.
● 1 kill switch (or key switch) which grounds modules to stop engine.
● 2 spark plugs.
