    HERE’S HOW IT WORKS
    Capacitor Discharge means that a capacitor is charged
    for a brief moment and when it discharges, the spark
    plug fires. To charge the capacitor, battery (or magneto)
    power Q is first stepped up to 400 volts by a dc-to-dc
    converter o This voltage is then stored in capacitor
    Q. The capacitor Q is controlled by a thyristor Q
    which functions as an electronic switch. It has a built-in
    gate that is opened by voltage pulses supplied by a
    signal generator Q mounted on the generator rotor
    shaft. The voltage pulses are the timing pulses. When
    a voltage pulse opens the thyristor gate, the 400 volts
    stored in the capacitor Q is applied to the primary
    ignition coil The secondary ignition coil @ steps
    up this voltage to 30,000 volts and fires the spark plug
    0. The spark plug 0 has a built-in booster that steps
    the voltage up even more.
    The superior advantage of CDI is that it never needs
    to be adjusted or timed — no moving parts to wear out —
    and it greatly improves low-end pulling power without
    sacrificing high rpm output. The result is a constant
    ignition system that eliminates miss-fire and provides a
    stronger power impulse with each rpm.
