Ok, Hydrocars.
I have made an attempt to replicate what you draw.
I have tried some coils and capacitors and a diode.
Drawing nr. 3
Step number 1 i have on my breadboard.
When i short the AP, i get a spark / bang.
And then i blew up my mosfet.....kak
I used the primary of my ignitioncoil with similar capacitors as you showed.
What is next?
