Odd behavior of a switch


W. eWatson

Jan 1, 1970
We have three light switches in a hall way, and stairs that lead down to
the lower level. One switch is on a wall, and two others on the
opposite wall. The walls are perpendicular to the hallway.

One of the switches stopped working, so we replaced it. At first it
didn't work, but now it does. I think we are OK.

However, for some years we've had mice get in to the walls. We've had
some concern that they may have damaged the wires. We live in a rural
area. Without opening walls what might be a good way to find damage?

I had a lot of the property cleared last year around our house to give
us a wider buffer for fire protection. Apparently, the mice didn't like
that, since it made them easily seen. We haven't had a mouse problem for
8 months.

I had the same experience with an old van where wood rats got into the
engine and caused some electrical damage. That is, I parked it in an
area that had little cover around it. No rats for over a year.
