Chris: I have not been "keeping up" with every detail of this thread, but
HERE, it seems you had simply "reversed" one of the windings! Swap the leads
on ONE of those two windings to be parallelled, and check again! (First, you
might want to MEASURE the AC voltage, no load, on each. Should be "close",
but not necessarily "exactly the same". Another test: Connect ONE end of
each winding to be parallelled, then measure the AC voltage between the two
"loose ends". Theoretically, assuming both windings were EXACTLY equal, this
should be ZERO V. AC.
