Need help with no spark

So jump across the two terminals that go to the ballast??

Yes, pull the wires off, use a short jumper wire and push it into each socket creating a connection like the ballast does.

I thought they say not to eliminate the ballast with the stock ignition or you can blow out the control box and/or coil...

It won't hurt a thing Karl, it's just leaving it that way and driving it that it "might" damage the coil or whatnot. I had to do it once on my 68 Barracuda, and I drove it about 200 miles with no ill effects.

Like I said, I doubt that's it because you said you had voltage on both sides when you checked it, but anything is worth looking at.
