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?
