Yikes! Okay, guys, thanks for the knowledge.

I checked the ground-plug-to-case on both machines and back from the
extension cords to the wall, and like, there's 0.5 ohms (even in the
trivial case).

There is something not quite right. The two items which have 101V between
them can't be commened to somewhere via a resistance of only 0.5 Ohms.


They don't have 0.5 ohms between each other, they each have 0.5 ohms to
the ground/earth pin of their wall outlets.


Right, that's what I wanted to say.


So the wall outlets have 101 Volts difference between them. Not hard to
do if they're fed from different secondary windings from the same power
transformer and/or one of the outlets has some dodgy ground/earth wiring.


And this gives me a clue of what I have to do - check each socket's ground
line against the radiator (I'll need a long line to do it).
