Open neutral. Induced voltage.


Digital meter are very high input resistance and can easily indicate
phantom voltages. Neon lights are not as bad but also can indicate. Plug
in receptacle testers also operate at very low current. If they indicate
an outlet is bad it probably is. If they indicate an outlet is good it
isn't necessarily. They particularly can't be relied on to test for a
good ground.


That would definitely explain zero voltages when breaker is off. And if
I short neutral and ground there's only 0.06 mA flowing.

So: given the induced voltages and wire guage is it possible to figure
out approximately how far back is the break in the neutral wire?


I don't thinks so.

Look in other boxes with devices on the same breaker. It will probably
be toward the panel. Likely possibilities are back-stabbed receptacle
through connections (good idea to convert them all to connection under
screw) or loose wire in a wire nut.
