I have a 3 way switch at the top of the stairs and one at the bottom that control the lights in the stairway/hall way. The problem that I have is that you can only turn the lights on from the same switch that the lights were last turned off from.
I have looked at many websites and videos and haven't quite seen the setup that I have. The home is not that old (13 years). I am not the original owner but I suspect that the house was originally wired this way because when I took off the wall plate, I had to cut the paint away from the wall plate and the screws looked fairly new still.
Unlike everything that I have seen online, the junction box with the hot black wire has another cable that examples don't show. For the sake of this description, I'll name Cable #1 as the cable housing the hot black wire. It is a 14-2 cable. Cable #2 is a 14-3 wire houses the red wire. Cable #3 is another 14-2 cable. Anyway, here is what I found.
Switch 1 has the following connections:
All ground wires are connected together.
From 14-2 Cable #1 with the hot wire: Hot Black wire connected to common screw. White neutral is to another 14-2 Cable #3 and is connected to the black wire.
Cable #2 is a 14-3 wire: Black and Red are connected to switch 1 gold terminals The white is connected to the white wire from Cable #3
I do not know where Cable #3 is going. I am assuming it is to one of the light fixtures.
The black wire is connected to the common screw. The red and white wires are connected to the gold terminals.
I have checked the voltage in switch 2 with the power on and switch one in the up position, I have 120v at the black and white screws with switch 2 in the up position. The red screw shows a voltage of about 60V. When I put switch 2 in the down position, the red screw now shows a voltage of 120V as well as the black common screw. The white now has very little current showing (about 3V). When switch 1 is in the down position (so that current should flow through the red wire), there is no current at switch 2.
I tried disregarding Cable #3 and connected the white wires together from cables 1 and 2. This resulted in blowing the circuit.
Also, I have moved all of the wires around at switch 2. The effect was that the lights came on with the switch in the down position but I still could not turn the lights on at switch 1.
I know this is a lot of information. Perhaps, I should either call a pro or live with the way it is but, I wanted to try and figure this out. Thanks for any help you can give.
