In reply to post 214, I would NOT like to see this thread split up between Kettering and CDI, and would like to keep the thread intact. I believe that the main source of confusion is the difference in design and coil requirements between Kettering and CDI spark generation circuits. I agree with post 220 that this confusion will continue whether or not the thread is split.

I believe that the confusion could be reduced or eliminated if an EE or manufacturer could briefly describe the design and coil differences between the two circuits so that we all could be on board here.
