Electronic 12V DC Capacitive Discharge Ignition (CDI) Circuits

Last Updated on May 16, 2026 by Swagatam 304 Comments

enhanced CDI

In the following post I have explained a simple yet enhanced 12V capacitive discharge ignition system which derives its operating voltage from the battery instead of the alternator for generating the igniting sparks. Since it works independently from the alternator voltage, without depending on a pickup coil signal, it is able to function more efficiently […]
