This is how to test an unknown disconnected transformer.

If the 40W lamp is fully bright, don't try the other wattages.
Either you have a short or the XFMR is sill connected.

Sorry to tell you but to test relays in a circuit you cant draw for us to see
is to much for you to try without vocational training.
