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!

I always have my little inductive tester with me to figure out which wire is
hot. You just touch it to the insulation and it only gives an indication on
the hot wire. It can also read through the outer jacket on Romex. I've
used several brands over the years, but have found the Fluke model to give
the least amount of false readings.
