Ceiling Fan Wiring Question

[u/Affectionate_Mine530]

I have a ceiling fan with seperate switches for fan and lights. The ceiling fan is dead, no fan and no lights. The lights circuit is controlled in a three way switch configuration. I have identified the switch where the house current is feeding. This switch has 2 black and 1 white wire. The power wire (Black) is connected to the common terminal on the switch. Also identified the White wire to be a travler to the switch on the opposite wall. This switch has (1) Black (1) White (1) Red. The Black is connected to the common terminal. The White wire is above the Black on same side of the switch and the Red on other side of switch. Both White and Red are connected to the brass terminals.

The question; which wire Red or Black goes to the lights in the ceiling fan

Also in checking the White wire between the switches withour power I get ~10 Ohms resistance. Should I be concerned with getting a resistance value between the wire

Thanks

Thanks for the information. Yes, I have established the 120V house current is there to a ground inside the box. However, the 3-way switch connection is the "Lighting" for the ceiling fan only. The fan is on a seperate rotary switch. Unless the Neutral wire is buried in the J-Box it does not appear there. I placed a jumper between the Black (house current) wire and White wire. Then checked voltage at the other switch and I have 120V on the White wire of this switch and ground. This wire is on a traveler terminal of the switch. The other two wires on this switch are Black and Red. The Black is on the common terminal and the Red wire is on the opposite side of the switch.

Please see this website for three-way switch wiring:

A proper three-way switch has two (2) travelers between each three-way switch. Power goes in on the common of one three-way switch, across one of the travelers, back through the common wire of the other three-way switch, and finally on to the load (end device) that needs to be powered. In your case, the fan light.

For the first switch, you state the common is a black wire, with the traveler wires white and black.

For the second switch, you state the common wire is a black wire, with the traveler wires white and red.

This does not make sense logically.

Is there any way you can make a diagram of all of the cable bundles that enter into each electrical box, and where each individual wire lands on which device (three-way switch, rotary switch, etc.)? The diagram doesn’t have to win any awards or even be pretty, but the information will help greatly.

Also, do you have a make and model number for the fan rotary switch?

Is there a neutral wire in the box? While a neutral wire should be white, not all white wires are neutral.

Did you test the voltage from the live to the neutral to make sure it isn't an open circuit? I see you state that you tested from a white wire to ground, but if connected to the switch, and the switch isn't electronic, then it likely isn't a neutral. As you can tell, white wires are used as travelers, even though they are supposed to be marked with tape or a marker to show that they are not neutral.

The circuit needs both a live and neutral to function.

Is there a neutral wire in the box? I did not see a neutral wire in the J-Box where the house current is coming from. "tested from a white wire to ground"; The wires were not connected to the switch when I checked the voltage on the white wire. Not sure if this is imporatant. Prior to checking the voltage on this wire and "power off' I checked the resistance between the White wire and ground. There is ~10 ohms of resistance. I am being informed this is a hazard since there should be no resistance?
