Re: BIGGG COIL'S NEW PROBLEM

Ed,
I just got some 1.0 mF 2500WVAC MO caps that I am planning to use to drive an ignition coil the way you describe off the 120 mains in series with a 600 watt dimmer. You say you pulled 30 amps. Did this trigger your circuit breaker? Are there any "anomalies" I need to look out for that you can warn me about? My ignition coils are very robust racing coils from my drag racing days. Three of them are rated at 50 kV and one is rated 60 kV. They are much larger than standard coils and contain a lot of cooling oil. I believe I can stress them pretty hard without worrying about burning them up. Even if I kill one, I have 4! You mention line glitches. Do I need to put an EMI filter between the plug and the dimmer to protect my house wiring? Any advice will be greatly appreciated. Regards.
Paul
