Re: [MBZ] OT - 3 Way Switch Wiring
Everything was installed to code. The issue was that the supply side of the circuit was at the other switch, not the one I had roughed in my "new" light switch at. To add insult to injury, there was an internal jumper in the switch that connected the supply (black) terminal of the three way section to the black (gold) terminal of the secondary switch. Needless to say, I pulled that bad boy out Just to clarify, this is in a single gang deep box, so I put a new switch in it that has two sections - a single pole section for my new lights, and a three way section for the existing three way circuit. My original plan was to simply jumper the supply from the three way switch to the single pole side and use that to power up the new lights. With the internal jumper it would have been down for me, but since the black lead in this case was not the supply, it wouldn't work Again, thanks to those who offered help. I knew I could figure it out, I was just looking for some additional brains to make it faster.

The neutral must be unswitched if you have only single-pole, double-throw (SPDT) switches. See the ASCII-art schematic of my earlier mail. What Dave describes is apparently what Dan already has. He can only turn on his task lighting when the main lighting is on. He wants to be able to turn on the task lighting when the main lighting is off.

Re: [MBZ] OT - 3 Way Switch Wiring
It would, but with the help of my trusty Fluke and some time I was able to determine that I am on the load side of the circuit, not the supply side. Fortunately, there is a receptacle close by that I think I can snake some timed to and get an unswitched supply from. Darn it. Thanks to all for the info and suggestions!

Re: [MBZ] OT - 3 Way Switch Wiring
If one of you whacked the switch with a vacuum cleaner or an elbow then it is possible that the switch broke. You will just need to put a test light on the output of the wall switch and see if you still get power. If that works, move on up to the ceiling fan. The test light switch, connect to one screw on the switch (at a time) and also the white wire (neutral/ground) - remove the nut. One switch screw should always light the test light. The other would make the test light go on and off as you flip the switch. If you have some kind of high tech electronic dimmer, it is possible that a power surge killed it.

Re: [MBZ] OT - 3 Way Switch Wiring
Diodes are not used in normal electrical wiring. It sounds like you have not identified the real power source "from the panel". Typical 3 way: 3way 3way ---POWER SOURCE HOT-X X-LIGHT Y--Y Z---Z It is possible that the light wiring hanging off the 3 way is in the same box as the power source 3 way. In that case, you would have a 14/3 type wire just going to the remote 3 way and a couple of extra wire nuts.

Re: [MBZ] OT - 3 Way Switch Wiring
I have no idea what the heck you are talking about. Speaking of which though, in my bedroom we have a double switch on the wall with a ceiling fan with light attached. One switch turns on the fan the other switch turns on the light. All the sudden the light no longer turns on but the fan still does. I thought maybe it was the light assembly so I swapped from another room still not working, one from bedroom worked in the other room. So I hope maybe I can figure this out without having to pay an electrician to come out. I know zero about home electrical stuff.

[MBZ] OT - 3 Way Switch Wiring
Yeah, I know how to wire a three way switch, but I have added a wrinkle... I have a three way switch arrangement for the lighting in my kitchen. There are switches at either end of the kitchen, either of which will turn on or off the lighting. A typical three way switch arrangement with two travelers, etc. This works just fine right now. Here's the wrinkle: I am adding some task lighting, for which I ran the romex from the "primary" three way switch to the lighting. I added a second single pole, single throw switch to the box. I tapped off the AC feed to the three way switch for the power to the task lighting switch. When the three way switch is turned on, the task lighting will turn on as well, if its switch is on, as it will turn off when the three way switch goes off. When the kitchen lighting is off, the task lighting will not turn on and as one would expect, there is no power at the input to the task lighting switch. While I haven't put pencil to paper and drawn this out yet, I am thinking that I am getting a back feed through the "new" circuit that is preventing it from working correctly. This doesn't make total sense to me, unless I am not at the box where the primary feed for the three way circuit is. Either this or the primary circuit is dropping to zero when it is on (potential to ground) because there is now a load on it, effectively cutting off power to the new lighting circuit. I am wondering if I will need to put a diode in series to prevent this from happening. Anyone want to wrap their mind around this one?
