Reply to comment by Cappuccino_Crunch in I have a question on wiring for a ceiling light. by Cappuccino_Crunch

The issue is the neutral at the switch showing voltage. That shouldn’t be happening. What else is on that circuit?

So I pulled out our map for the electric that we made. https://imgur.com/a/51ir7wO. I'm working on 28. I'm guessing that open neutral is what the plug tester read when we went around testing the outlets. I have a bad feeling lol.

Work your way backwards through that circuit to find where the issue with the neutral is.

Is that what's causing my issue? And work back towards the main from the point where it says open neutral?

Yes. Somewhere upstream, the neutral is crossed and is picking up voltage.

Thanks man you've been super helpful. My question is why doesn't the rest of the outlets show that open neutral on the circuit downstream? Is it because I separated the two circuits at the switch?

That I’m not sure. Something like that is hard to diagnose without being there and seeing it.

Alright cool. I'll open that outlet tomorrow tomorrow and the ones upstream to figure out how to fix the neutral.

Now I'm at a loss. Gonna call in a pro now.

Actually, I think I see the problem. Disclaimer: I’m not an electrician, just a somewhat experienced amateur, but for the life of me, I don’t see why that neutral is bundled and capped with those hot wires. That’s likely where your neutral picking up that voltage is coming from.

I will gladly step aside and admit defeat if a professional wants to contradict this answer.

Ok. So what should I do with that neutral? There's three bundles in there. Two go to a light switch/fan plate that operate on two different breakers.

Ok, disregard my previous comment. How many b/w pairs are in that box? There should be 4: two on the hot side of each circuit and two that lead downstream.

Disconnect and separate everything. Then organize the wires by pair. Then, test to see which is the hot coming in from each circuit. Then you’ll have to do a little trial and error to see which of the downstream pairs goes to the light vs the switch.

Confirm this and let me know.

I only have three pairs. This seems like a good stopping point for me actually lol. Running a switch to a light seems pretty easy. I appreciate the help though.

Is that a split outlet? In other words, does the switch control one half of it and the other half is on the other circuit? If so, I have your solution.

The circuit that the switch is on was designed to terminate at that spot. With the power and the switch on, find the hot wire for that circuit. Then, connect that pair to either the top or bottom of the outlet.

With the remaining two pairs, you’re going to have to make two pigtails. Take a spare piece of black/white wire accordingly and cut off about 9-10”. Strip the ends and with a wire nut, bundle the two black wires in the box together with one pigtail, and do the same with the white. Connect the other side of the pigtails to the open half of the outlet accordingly.

I'll just call an electrician tomorrow to figure out this neutral issue. Is that what's causing the light fixture to not work? If so I'll do the hook up myself since that part is pretty easy
