What is a Capacitor Discharge Ignition (CDI) & Its Working
The trigger circuit is a switch, probably using a Transistor, Thyristor, or SCR. This triggered by a pulse from the Hall Sensor on the stator. They only allow current from one side of the circuit until they are triggered. Once Capacitor C1 is fully charged, the circuit can be triggered again. This is why there is timing involved with the motor.
Capacitors
In the low-frequency passing, subwoofer circuit, high-frequencies can mostly be shunted to ground through the parallel capacitor. A very simple example of an audio crossover circuit. The capacitor will block out low frequencies, while the inductor blocks out high frequencies. Each can be used to deliver the proper signal to tuned audio drivers.

The "P" in P-lead comes from the primary winding in the magneto''s coil. To deactivate the magneto, the primary winding is grounded. An ignition switch opens and closes the P-lead circuits to a suitable ground. The internal workings of an Off/R/L/Both ignition switch contain the required connections.
21.6: DC Circuits Containing Resistors and Capacitors
RC Circuits. An (RC) circuit is one containing a resisto r (R) and capacitor (C). The capacitor is an electrical component that stores electric charge. Figure shows a simple (RC) circuit that employs a DC (direct current) voltage source. The capacitor is initially uncharged. As soon as the switch is closed, current flows to and from the initially uncharged capacitor.
