I'm trying to hook up a new light fixture and when I removed the old one, what I saw confused me.
The taped wire on the far left seems to be coming from the switch, I've tested with a voltage reader by turning on and off the power and testing from a distance with a wooden yard stick.
The bundle of black wires second from the left was within the box already when I took the old fixture off.
The remaining two wires are seemingly a neutral on the far right with the yellow cap (no voltage with power), and a hot that's constantly on.
When I first hooked up the fixture, I could power the fixture from the switch, and it seemingly worked fine. I had only hooked up the switch wire to the black from the fixture and capped off the remaining hot thinking it was from a fan the previous owners might have had. I then noticed that two rooms did not have power, realizing that the remaining hot needed to be hooked up, somehow.
I've tried seemingly every combination I can think of, even tripping the breaker at one point due to I think a live and neutral being capped together.
A couple of observations I've made:
- If I connect the fixture black to the continuously hot black, the lights flicker, and the upstream rooms also flicker on and off, and the light switch doesn't work
- If I connect the fixture black to the switch black, the light no longer turns on and off from the switch and nothing is on downstream from the fixture. Note: I can still turn the switch on and off and read voltage through my jury rig that is extremely dangerous I'm sure.
- If I connect all three live wires together (fixture black, box continuous hot, and switch hot), it's similar to #1
My questions are:
- What are these bundles of three random black wires?
- Did the circuit tripping end up short circuiting the switch, and that's why everything else is no longer working?
