Geez, now I'm really scratching the twins. Upon testing with a
tester, I don't get anything. When I hook up a test wire and run it
to a spare lamp, the lamp lights. Apparently, the transformer is
still good. I can see no user serviceable fuses or resets. I'm
going to pull the cover and look inside, but at least I don't have to
go buy another one.

Probably needs a load to do its thing.
