Thanks Bomb! Ive seen that onlinepot diagram 10 times and it never registered that I have the black & white wires crossed in my diagram. Exactly the information I needed.

NOTE TO READERS: My hand drawn diagram above is incorrect and possibly dangerous - the black & white wires from the wall outlet need to be swapped white goes to common (yellow on my ballast), black to 120v tap on the transformer (black & yellow wire on my transformer).

In the interest of safety, a MOD may want to delete this thread of mine altogether. I would hate to have someone use my diagram and have catastrophic results.
