Well, all is working now. I had blown a fuse messing with the wires. I think that I blew the fuse on the neural, so nothing made sense. All the guides on the internet assume that your neutrals are not fused, but as I said before, this is an older home... Anyway it works well now, I had to swap in an old light bulb instead for 4 LED bulbs to get consistant responses. Thanks for the help!

Ok, I can try unscrewing the light bulbs and see if only one line shows voltage. That makes sense. I'll report back tomorrow.

I don't know is this is the right spot for this, but.... I am trying to install a Aeon Labs Nano Dimmer that doesn't require a neutral, but I need to differentiate between line and load. I have K&T wiring and just have two unmarked wires. When you touch them together, the light comes on, when you separate them it doesn't. I expect that it is NOT a switch loop, but rather a hot from somewhere that stops at the switch and then continues on to meet the neutral at the lamp. K&T wiring was done like that, as it doesn't come in the form of a cable and you didn't have to parallel the lines back then. I can't tell which is line and which is load. I tried a multimeter to a ground and both show to have voltage relative to the ground. How to tell which is which? I know at least one of the wires should run back to the fuse box and one to the lamp. This house is about 95 years old, we have fused hot and neutral lines. Will I mess up the Dimmer if I install backwards? Any suggestions?
