Hello coilers. I've got a 3.3nF capacitor with 40KV DC (Cera-mite). The guy who selled me this said, that I can use 9KV AC with this capacitor. He works very well with a NST. But can I use a car ignition coil with the capacitor as well? The arc from the coil is approximately 1.5 - 2 cm long and has an orange color. Thanks a lot yours Tom
