Most of my wiring is updated, but I have a few light fixtures left on knob and tube. I was going to replace a light fixture, but I can't figure out which line is hot vs. neutral -- the wires both have the same colored loom.
I have a cheap voltage tester, and when I got it close to either wire (which are about an inch or two apart from each other), the device goes crazy -- I'm assuming the wires are too close for the tool to distinguish which on is hot.
Anyway, any tips on how to decide which wire is hot vs. neutral? I want to install my new light, but don't wan't reverse polarization issues.
Thanks for the help!
