Kobuchi,
The voltage readings don't make sense, given the info you've supplied. More data is needed. This text based forum is not made to handle this. You get high marks for asking the question. The recommendation to bring a pro to the job site is not a rebuke -
you have a bad opinion of people like myself.
The problem, as you state it, in my experience, has all the earmarks of a really good puzzle worthy of even the best electrician. Caution flags are raised by the symptoms. Don't let this one coast. No shame in passing the baton.
