Re: 3 way switch blues


Okay that makes sense, One black is power coming in. See in this picture they have connected white to black in both lights.

Re: 3 way switch blues


If you didn't touch the switch boxes then don't mess with them now.
At the lights consider the 'tan' to be white. Connect all the blacks together including the fixture.
Connect all the whites together including the fixture.
If you have no voltage black to white, but have it black to ground, when the switch is flipped then you have an open white somewhere else.

Its 2 cables that come into the box. No the black isn’t pigtailed to anything. The two whites from both cables are pigtailed together and both grounds from both cables are also pigtailed together

Black to ground shows 122 volts, black to white shows 0 volts

I also used the little plug in to check all the outlets and they were all good. The only other thing besides this setup on this circuit is a ceiling fan

Ceiling fan has black and blue going to the black hot. White to white and ground to ground and it works perfectly. The outlets also work perfectly, only the hall lights don’t work

Open neutral somewhere for sure.

Somewhere there is a neutral either loose in the splice or actually broken from being moved.

Re: 3 way switch blues


At one of the switches (we don't know which one right now and we don't care) the 2-wire cable with a black and white wire is the power in cable. The black is hot and the white is neutral. The 3-wire cable goes to the other switch. We are not worried about the ground wire, it is there for a reason but it is not part of the circuit. The white neutral of the 2-wire cable is connected to the white of the 3-wire cable. So the white of the 3-wire cable is used as a neutral. The hot black of the 2-wire cable is connected to the common screw of the switch. The common screw is a different color than the traveler screws. The red and black of the 3-wire cable are your travelers and are connected to the traveler screws of the switch. It doesn't matter which traveler wire is connected to which traveler screw. When the switch is in one position a connection is made between the incoming hot black wire and one of the traveler wires. When the switch is in the other position the a connection is made to the other traveler wire.

At the other switch the white of the 3-wire cable (neutral) is connected to the white of the 2-wire cable which goes to the first light fixture. The black and red traveler wires are connected to the traveler screws of the switch. The black of the 2-wire cable is connected to the common of the switch. When the switch is in one position, one of the traveler wires is connected to the common terminal. When in the other position the other traveler wire is connected to the common. When both switches are in such a position that the same traveler is connected to the common of each switch the light burns.

If one switch is changed the light goes off. If both switches are changed the light comes on again.

There is nothing wrong with your wiring at the switches except that the ground wires should have a wire nut on them to prevent them from separating.

At the first light fixture the two whites should be connected together and connected to the light fixture. The two black wires should be connected together and connected to the light fixture.

At the second light fixture the black and white wires should be connected to the fixture.

If the light didn't burn when you put them back up that means you didn't make a good connection at the first light. If you were able to run an neutral from somewhere else and the light burned, that means that the poor connection was in the white wires.

The neutral connections in the switch boxes all look good.

Check your neutral (white) connections in the first light fixture.

Re: 3 way switch blues


Now you are talking about a fan/light.

If the fan/light and the hall ceiling light are on the same circuit (and very well could be) look in the box of the fan/light for another white wire that has been disconnected.

I didn’t think the fan/light could be the issue since it worked. I pulled all 4 boxes out of the wall and everything looks perfect. I’m going to remove the fan tomorrow and the box to take a look there.

Got a peek at the ceiling fan and saw 2 wires on the left not off of the main cable tucked inside the box. I pulled it out and it’s reading 120v to ground. Will do more discovering tomorrow

Removed the fan and it has 2 cables within the box. Why would the hot of one cable be connected to the neutral of the other cable? So the fan used the neutral from one cable and the hot from the other cable.

I also just noticed that the led light is in fact on in the hallway but it’s not bright enough to actually see without looking into the housing.
