We recently moved into our first home (built in 1950's). We are looking to replace the door bell (well the chime part hanging on the wall). Everything works fine, we just don't like the look of the original one and want to replaqce it with the simple white chime box. I have removed the cover (to the original) and it consists of just 3 terminals, front, terminal, and rear. I figure these are for front door, power, and backdoor. These three wires are simply coming out of the wall (with a wire nut). The original chime appears to be a NuTone from 1956. My new door chime says to ensure I'm hooked to a 16V transformer. I don't see anything there now as there are just wires coming out of the wall and a wire nut. Looking at the new chime it doesn't appear doorbell technology has changed much (as it has the same
3 terminals), can I assume there's a 16V transformer in the wall somewhere? Is there a way short of buying a voltage meter to tell? Thanks!!- posted
