When looking at how to arrange the negative side connection ports on the circuit board I realised that if I connect the capture capacitor to the main negative rail of the generator then I am effectively bypassing the cap dump circuit which switches the negative line back to the batteries in order to release the stored charge. I have shown this in the attached pic and where the cap dump circuit is traditionally connected to an independent coil. In my case the HV pulses are being generated in relation to the battery negative/ground (FET Source) and so I can't connect the negative of the capture cap to that as it will discharge straight away.
I wondered if you can think of a simple solution to this?

Jules
