Up in the attic. Have to bring hot wire to junction box with three legs
going out. Each leg goes to ceiling light of different rooms. YES, I
can power them up and the wall switch in each room turns on its
respective light. BUT, what's an easy way to test that I don't have hot
and neutral reversed. The old romex in the attic (two wire, cloth
wrapped) is NOT color coded in any way.

Do I simply drag a neutral wire from a different circuit and probe the
bulb socket in each room? Is there an easier way? My A.C. voltmeter
obviously does not indicate polarity.

All replies appreciated. Sheetrock guy is coming tomorrow a.m. and I
have to solve this today!

better, drag a wire from a good ground (water pipe) and check voltage
against that. Heck, if you're in the attic, why not just add
supplemental grounds and/or pull new romex to replace the old cloth NM?
If you can't pull the whole circuit, do what you can and then wire a
supplemental ground from where you started repulling. Best would be to
take it back to the breaker box but if you can't do that any ground
point is acceptable per code (unless they've changed it recently.) Only
thing that *wouldn't* be acceptable would be to repull some of a circuit
so it would appear to be grounded but to not actually connect the ground
wire to a real ground.
