Ed,
I suppose you have done this already and you can flame me if I
am stating the obvious but there is one thing that might account for
all this (did I hear a bell ring?).......

If your secondary is OK, one thing that might have been altered quite
drastically in the rewiring process is your tune. I can't think of a
single other reason why your system is performing so poorly. Unless
you have formed a shorted turn in close proximity with the primary,
the strap shouldn't affect the system noticeably.
