Cause/Effect
With this being the case the Diode side is just acting like a larger resistance and lower potential than the spark gap side. If this works like the diagram, wouldn’t this discredit the idea that the LV is following the HV over the spark gap? It would appear to me that the effect is caused by like polarity charges (one LV and one HV) colliding at the plug gap. Unless HV jumps the gap at which point the LV high amp side overcomes the HV (Reverse direction) and uses the HV bridged spark gap as a path to ground or N in this case. Any other ideas how this is possible?

In my tests, the cap (22uf 250V, couldn't find a 12.5uf) made NO difference in anything, no matter which configuration it was wired in. I even changed the coil configuration to discharge - instead of +, still no good. Each time I flip on the inverter, the "continuous" spark at the plug just sits there going crazy. After about 5 seconds, the inverter starts to squeel so I flip it back off. I never even activated the discharge from the coil during this, since I instantly fried the inverter by discharging the coil into it yesterday. And does anyone know what kind of cap Mr. Bill is using in that video? That thing is huge. Is it a non-pollarized or something, or just really old? I didn't fry any inverters today, came close about 10 or 15 times though!
