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.
