Wow. So, bottom line is, an analog meter is the only thing you can
really trust?
I believe there was a trick to make a digital meter NOT show phantom
voltage, but i don't remember what it is.
Simple: put a large-ish resistance (say, 50-100K ohms) across the
leads to reduce the input impedance. This will shunt any phantom
(induced) voltages away from the meter.
A light bulb is better else you may forever have imprinted on your memory
the smell of a burning resistor.
