Shorted doorbell transformer? (alien.top)

Moved into new house and previous owner took their ring with them and left exposed wires where a doorbell would be. Had no idea if the doorbell even worked (never thought to test it) friend offered to hook up a new ring for me and I think he shorted the transformer as, during install, it got insanely hot and smelled like it was burning. Ring never worked during install. He unhooked everything and we hunted for the breaker to shut off transformer. Transformer is in a hall closet about 8 inches from a light on a switch, so likely same circuit. We flipped every breaker and not one turned off the light. Only the main shut it off. After reversing everything he did and waiting for the transformer to cool down and the burning smell to go away, he said we could test the bell by simply touching the 2 exposed wires for the doorbell together to complete the circuit. We tried that and no sound. Did the transformer fry? Is it common to be wired to the main? House built in 2016.

Disconnect bell wire wire from transformer and measure voltage at the screw terminals. Should be 24VAC. If nothing, internal fuse link in transformer is open. Transformer is toast.

Tested and it is dead. Time for replacement
