If you had the meter on the ac range (as you should have to read the
voltage on the transformer), you picked up a stray voltage...or not. If
not, then more investigation is necessary. I believe somewhere in the
thread, you stated the transformer was open on one side or the other.
If that's the case, you picked up a stray reading...phantom reading
which is indeed real, but not useful with respect to a determination of
your problem.

OK, but why would I put the meter on the AC range when the transformer
is supposed to be outputting rectified voltage?

A transformer doesn´t output rectified voltage. It outputs AC voltage,
which is rectified and filtered by the diodes and capacitors following
the transformer. That´s why there are diodes, capacitors and voltage
regulators after the transformer: to convert the AC unregulated voltage
of the transformer into regulated DC.

OK, so why would I put the meter on the AC range to check the
regulated DC voltage coming out?
