Glad it did not zap you.

Would a fly back work?

Yes, a flyback transformer would also work,...but I don't have one of those in my spare parts box either. So, I'ld need to order a flyback and incur the same week to 10 day shipping delay. Having a short inside the coil's insulation is pretty rare,...hopefully it's a one-time occurrence for me.

If it happens again, the old school neon sign transformers work well.

Shortly after typing my last post where I mentioned how rare it is to have coil wires inside a transformer develop a short, I remembered that I never had a problem with the coils (aka transformers) on the two previous high voltage boards, which suffered shorts on the high voltage circuit boards, but the coils were undamaged. So I dug through my spare parts box, and lucky me, the coils on the dead circuit boards were the same as the shorted coil. I was able to replace the shorted bad coil with a good one from the bad circuit board, and now my ignitor board is back up and working

So out to the test stand to make a little steam.

Well, a little steam was all I could get. The burner flame keeps going out periodically, causing an auto re-start sequence. So, I'm sitting in front of my computer trying to understand why this is happening.

I've got some ideas,...so back to the test stand for a little investigation.
