David-
Biggest source I have for ex is 13.8. I could make a voltage doubler or quadrupler and see if that does anything. I tried it with just two caps with the bleeders cut off and not connected to the rest of the bank and I don't get any sparks from them. When I short it out after charging for around 20-30 seconds. This sucks. Just finished it today and tested it for a couple hours of an on while tuning it to get about 12-13" arcs to air. Only ran it for 8-10 sec each time. Soon as I hooked that variac up it did this.. Guess I'll buy more caps and see if that works. In the event I replace the caps and still nothing happens do you got any other ideas what it could be?
