You should see an AC signal from the transformer. It sounds OK.

also shows when it's not connected to anything).
Well, showing 0.0 ohms indicates a short circuit and "1" would indicate an
open circuit - two very different things. If it was a short circuit, the
transformer would blow its fuse when it was connected, so it sounds more
like an open circuit - a break in the cable.
You didn't indicate what the problem was. No heat? I would guess a
broken cable. Is it already installed in the aquarium? Did it ever work?
If you can?t respond today (11/22) I can?t be of much more help - I'll be
away until Dec 4.
