Ignition Systems

These systems use a capacitive discharge (CD) coil. With CDI ﬁ xed timing, 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. MDI adjustable timing uses a digital microprocessor which is located in ignition modules. Ignition timing

varies depending upon engine speed with this system.

A typical ﬁ xed ignition system consists of:

● 1 magnet assembly which is permanently afﬁ xed to ﬂ ywheel.

● 2 electronic capacitive-discharge or magnetic discharge ignition modules which mount on engine crankcase.

● 1 kill switch (or key switch) which grounds modules to stop engine.

● 2 spark plugs.
