My family has just moved to an older home, and I've been tasked with repairing the doorbell(s).
We have two doorbells, both connected to the same (for lack of a better word) ding-dong-thing.
:) I measured the voltage drop across the two screws on the transformer, and it read ~16V(AC) (+/- 0.5 VAC). So, I know the transformer is working.
When I measure the voltage drop across the terminals on the switches, the one on the back door reads ~3VAC, and the one on the front 0VAC.
So I conducted my preliminary Google search, and the results I found basically said to give up at this point and call an electrician, as there's probably a break in the wire somewhere.
However, this is a one-story house with primarily unfinished basement, so I think I probably stand a good chance at finding a break in the wire.
My question is twofold:
- Is it correct to assume that the problem is a discontinuity in the wires somewhere?
- How should I proceed to find a break in the wire?
