Does the bell push light go out when you press the push?

Normally the bulb is wired in parallel with the push contacts so the fact that it is on indicates you do have a complete circuit and that the transformer is working. But it should go out when you press the push as the contacts will short-circuit the bulb

Also try disconnecting the push wire from terminal C1. Then take another bit of wire (any electrical wire will do) and connect one end to terminal V/AC (along with the other wires that are there). With the transformer on, touch the other end of the 'extra' wire to C1. Anything? Touch it on C2. Anything then? Your extra wire is, of course, acting as the bell push and its connections.
