I recently got a call to trouble shoot a light. No big deal, until I got there. The house is old and has knob and tube wiring in the attic. The light that I am to trouble shoot they are not sure when it quit working, but they think that it used to work. I found romex going to a single gang double switch from the porch light that was not hooked up with two black wires in it and no neutral. I don't know where the neutral goes or comes from obviously bad news. After some investigation and frustration I came to the realization that I need to figure out a new plan of attack. I was going to get power from the switch that is already in the box, this is the knob and tube. When the light is off I have power to the switch and non off the switch leg, when I turn the light on there is no power at the switch at all. All the switches in the house do this (there are only four). As I don't have many years under my belt and most all of it is comercial/genset this is my first knob and tube experience and I am lost. Any help would be great.
