my house is 1988. there was a door chime in our hallway and two buttons, one front one back. when I opened the bell, I saw three wires. I assume one to front, one to back bell and one to transformer. how come, when I put my meter to all three wires, it shows NO power? yes, the breaker is on. (I untied all the wires)
any ideas or thoughts?
thanks
