I bought the stud-mount diodes Randall suggested from Surplus Electronics.
They arrived yesterday and I put them in. But the outputs were pretty much
the same as before I changed the diodes. Max DC out in "Charge" was only
around 11 volts, with 4 to 6 volts AC, which I took as indicating a bad
diode as before.
After stewing all night and checking this and that, I finally had a
fortuitous stroke of near-average intelligence, attached it to a battery,
and checked again. D'oh - it's fine.
Are open-circuit voltages in battery chargers always misleading? I didn't
expect the transformer output to go up with a load. Doorbell and toy train
transformers don't seem to do that.
Anyway, it's working again - thanks to all!

here's some that should be good enough. 60 amps continuous, over 1000 amps
peak. $3 each.
