I’ve just installed a Ring 2 doorbell for my father in law.
The battery was fully charged and the Ring doorbell is working fine.
Unfortunately the mechanical internal chime is no longer ringing.
Then I touch the 2 wires together, it works fine.
As soon as I connect the wires to the Ring doorbell and press the button, the internal bell no longer chimes.
When I installed the same doorbell at my own property I did not have this problem.
Any advice would be gratefully received.
