Paul,

Found this CDI design from 1999. Thought it might be useful as it
includes the transformer windings.

Yes I have one. Look in the Aussie-CD folder in that thumb drive I gave you.
Aden Lindsay gave me one way back. I forgot I had that transformer.

It was unreliable. I kept burning out power FET's.  However I can use that
transformer to test my micro processor control design.
Perhaps the problem I had was the way I was powering the system.
I was using a 12 volt power supply that was probably partially shutting down
with a current limiter. A 12 volt battery would not have that problem.
