1.	Eliminate the obvious! Get a cordless one then the wire (the thing
that was reused) is eliminated.

2.	Disconnect the doorbell and megger the wire establish its faulty
(resistive probably) and replace the wire.

3.	Remove the batteries and fit a battery eliminator the wire is then
not important until it fails completely.

4.	Remove the lamp from the bell push that causes the battery to
discharge.

Cant think of anything else there are only four parts in a doorbell the
battery, the bell, the switch and the wire.

Subject: [EE]: Help troubleshooting door bell

What would you do in my situation here?  We bought a door bell that runs on
batteries and I connected it to the wires that lead to the button outside.
Within a few days the batteries are dead, so it seems there is some sort of
short or something like that.  We just found out the previous owner had a
problem with the door bell, too, probably the same thing.

I'm kind stuck about how to figure out the problem and fix it.  Would anyone
mind please giving me some hints?  

Thanks!
Lindy
