2 hots no netural


I'm going to put in a ceiling fan with lights in my living room. In the light switch box the 2 wires coming up into the box are hot. The 2 wires in the ceiling one is hot coming in from the opposite direction than the switch the other dead (its not hooked up at the switch.) Its the old knob and single wire. I'm not sure what I want to do with this. any suggestions???

What are you using to check for voltage, a meter or a non-contact tester?

If its knob and tube, there would be no ground present. What are you putting the leads to get a reading?

Your OP is a little unclear. Are you saying that there should be two switches that control this fixture box?

Most likely the two wires at the light are neutral (dead one),
and the other is the switched supply from the switch.

The two wires at the switch are hot in and hot out (switched).

Did you note the connecttions before you took down the old light ?

What colors are the wires on the fan ?

There was a way of wiring a 3 way switch circuit where there could be 2 hots up at the fixture. It was called a Chicago Three Way. Its not legal anymore, but what you had was either two hots (light off), two neutrals (light off), or a hot and a neutral (light on). Based on the knob and tube, it is possible this is what you have. You may be able to rewire things to make it work correctly, but it is going to be very hard to do here.

This may give you a better understanding of a Chicago Three Way...

and if it was wired up in the chicago three way it would be preferred to just use 1 switch so how would i rewire it. would it be easier to run new wire?
