That's understandable. ?The boxes are not grounded in a knob and tube
wiring
system and the other wires are not neutral conductors. ?Run a long wire
from
a metal water pipe or from the neutral bar in your fuse box and use that
as
the second conductor for your tester. ?You should be able to find the hot
that way.

Thanks again. ?I tried that and it didn't work. ?I connected the wire to a
metal cold water pipe near each of the switches and tried using that as the
second wire for the test. ?So, something else is apparently goofed up
somewhere. ?I'm going to buy one of those voltage testers today and see if I
have any luck with that. ?I doubt it, but it's worth a try.

use a 25 watt light bulb never a digital VOM it will give you unusable
readings by capitance coupling

He is going to get an inductance pocket tester which is about all that
will work with knob and tube. (and a "for sure" bonded water pipe)
