sorry, more questions.

In the early schematic there was no resistor in parallel with the high voltage cap, but R11 (10meg) is there now. Also R9 has been added (10k). Could you just let me know the function. I'm guessing R11 is to discharge the cap when the ignition is not turned on, and R9 is to limit the switching current through T1, but maybe I'm wrong!

Cheers,
Rich
