Electrical Problem - Need Help!!
Hey guys!
I have an issue where there is no voltage going from the wire at the junction box to the light switch. I checked with a AC detector, all wires that comes to the junction box beeps EXCEPT for the wire that is going to the light switch.
I assumed that the wire might have been bad somewhere from the junction box to the switch so I disconnect the old wire and installed a new wire, check with a detector again, but still no beep....
Any ideas? Please let me know! Thank youuu!

Hi, through the detector away, get a multimeter, it’s doubtful a cable would have gone bad, what is the problem you are having? is it a light fixture that is not working, have you replaced the bulb with a known good bulb ?
How many cables in the box? Post a pic.

There is no power at the switch. Correct me if i'm wrong but there should be a constant 120AC volt going to the light switch. Turning the light switch on, completes that connection and turns the light ON.
Currently, the wire the leads from the junction box to the light switch have no voltage going through it, which it should.. Correct?

Yes the switch should have 120 volts across it when open.
0 volts across it when closed.
I am having a problem understanding what is going on here.
You have a junction box with 120 volts going into it.Correct?
It supplies a number of circuits. Correct?
Is the hot wire that goes to the switch tied to the hot wire 120 volt in with a murret/wire nut?
Have you removed that wire nut to be sure there is a good connection in it?
Then this wire goes to one side of the switch and the other side of the switch goes to your light fixture. Correct?
0 volts across it when closed.

Is what you are calling a junction box actually the ceiling box where the light fixture is located?
Is power from the branch circuit going first to the light fixture or to the switch first?

manden,
Yes from what I can see, the hot wire is connected to the wire leading to the switch. ALL wires at the junction box/light fixture (sorry if i'm using the wrong terminology) has voltage going through them with the breaker on, EXCEPT for the wire going to one of the light switch.
