Here is a rather odd one that happened to me.
While watching TV (newer magnavox tv with a L1 chasis + S4 chasis)
I happened to reorient the TV Antenna and touched it against a metal pipe
from the Fuse Box. TV died instantly. I blew a 1.5 ohm resistor and 2 diodes
on the power supply.
After the TV was fixed I measured 125 volts AC off of the Antenna on the
S4 chasis TV and 75 Volts ac off of the L1 chasis to ground. If I reveresed
the leads on the meter I didn't measure a thing?? This is AC so It shouldn't
mater which way you hook the meter up. (Yes, I did try 2 different kinds of
meters 1 Simpson and I forget what the other is.) These are non digital
meters (which I should try using.)
I tried measuring voltage (ac) from the Ground of the outlet to the
pipe from the fuse box and got 5 to 10 volts ac where there should be none.
Is this a ground plane problem or just something not hooked up right in
the house. A friend of mine siad that the voltage from ground (of the
outlet) to the pipe from the fuse box could be because of the way the
electric stove is wired. Some weird way how the electric code differs from a
house and a commercial place.
