Doorbell Help

I am trying reinstall a doorbell. I have 120 from the breaker to the transformer. Then when I hook up the wire to the doorbell and chime the transformer is blowing.

I had tested the continuity of the line to the bell, as well as the line to the chime. Everything looks good.

I have tried to wire the bell straight to the transformer bypassing the chime ...blows the transformer. I have tried a differnet set of wires in the run....blows the transformer.

Any ideas?

For your understanding, you need to have 1 wire from transformer to trans. screw on chime. 1 wire from trans. to button. 1 wire from button to front or back door screw on chime. Understand when I say wire I mean conductor as you probably have twisted pair wiring with multiple conductors.
Curious, you say you have both bell and chime on the same door button?
Usually a bell or buzzer is 10 volts and chime is 16 volts.
