Check the transformer with meter.. Bad transformer to start with ?? Did you burn it up on the install. If you shorted the line voltage you killed the 24 v side. If you short the 24v side you kill the line voltage side

Did you get the primary and secondary crossed?

Check the resistance of each winding.
If they don't read infinity see if you can get ~27vac out of the open-circuited low voltage winding with the primary winding being powered.

It doesn't sound good, so far. If you get another 'former, fuse it before installing.
