With no load.

It used to put out plenty. I've only used it a little bit since then.
If windings in secondary were shorted, output voltage would go down,
but what would make the secondary short?

Left outside, plugged in and charging a crummy battery, for about a
week, but covered from the rain and it didn't rain anyhow.


Are you sure it's the transformer?
What does the secondary read when disconnected from the rest of the
charging circuit?

Rectifier bridge(a module or 4 diodes pack) can have a leg open or short.
