I don't really want to get into the "upside down" debate, but just remember in the future to select the correct polarity when capturing secondary for the sake of posting. It helps that everyone is viewing the waveforms in the same way, also, when you have the incorrect polarity chosen, it will clip off the true spark KV. The waveform at the top is yours but inverted.

Thanks Preston for the reply I am still trying to learn all of this, I wish i would have caught the "upside down" waveform before I posted on here, but I will check the next one before I post it. Thanks again for your input

No worries, that's what the test board is all about.
