Electronic 12V DC Capacitive Discharge Ignition (CDI) Circuits

Last Updated on February 16, 2021 by Swagatam 299 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 […]
