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.
doco Reviewed by doco on . Raw MH Ballast Wiring I think this really belongs in Growroom Setup but I don't seem to be able to post my diagram in that forum so here it is: I picked up a raw MH ballast with capacitor and I'm ready to wire it up. Can you guys look at this diagram and confirm or correct what I have in mind? Don't wanna smoke a new bulb or my house if I can help it. Rating: 5
