Two 3 way switches, two lights already wired
Comments (14)The wiring may not be conventional because the power or the light circuits are not coming into the switch boxes and some creative wiring was done. The easiest way to figure this out is to first disassemble all switches and lights to access the wiring. Find out which wires in each box have power and make a diagram. Next shut off the circuit so you can check each wires resistance/continuity. This will allow you to determine which cable is feeding where. With a voltmeter/DVM set to OHMS pick the first wire to check and make sure there is no continuity. With the meter still connected to the wire go to the light or switch box you think the wire is running to and touch the same colored wire to ground (this is assuming it hasn't changed color by a connection somewhere else). The meter will read close to zero ohms when the wire is touched to ground (some wires may read a low resistance if it is connected to the light bulb so you may want to remove them). Do this for each wire until you have a diagram showing where all wires are going/coming from. Then is is a matter of having the wire supplying power go to the common of one switch. The two other wires in that same switch box must get to the other switch. The other switch will have the two wires coming in from the first switch and then the wire going to the lights connect to the common of switch 2. It now is a matter of connecting the wires through all the boxes to achieve this configuration. If you cannot figure this out then a picture of where all the wires go to the switches and lights.

Comments (2)Yes as ronnatalie stated there is an exception, when the power is brought to the light fixture,then the white of the(2) wire going to the switch is connected to the "hot" or black power wire.This wire(white) is used to bring the power to the switch, then the black(2) wire brings the power back to the light from the switch to turn it on......This 2 way switch connection is wired different from the 3 wire light connection as stated below. One example of a 3 way switch connection is: the black power wire bringing power to the switch is installed on the black screw of # (1) 3 way switch, and the white,neutral in this case is connected to white wire of the 3 wire,( blk,red and white), going from #(1) switch to #(2) switch,and connects to the white 2 wire coming from the light.The black wire also coming from the light connects to the "black" screw on #(2) switch. The remaining red and black wires, "travelers", from the 3 wire connect to the other 2 screws in the same position on both switches, e.g,black on the top and red on the bottom of both switches. This is the sequence if the power and light fixture wires are at different switches. If they are in the same switch area, there is another sequence. Hope this helps...See MoreWiring Multiple Lights on a 3 way switch
Comments (6)When all is said and done, four wires are needed: - One neutral wire to feed the lights and to continue from light to light. This is because each light has neutral connectivity whether the lights are on or off. Let's call this the "neutral jumper". - One wire which is hot only when a combination of the switches results in an "on" condition. If it's hot, the lights are on. If it's cold, the lights are off. Period. Let's call this the "switched hot jumper". - Two wires used for alternative paths between the switches which we'll call "travellers". They are complements in that when one is hot, the other is cold and vice-versa. As long as the circuit is in normal operation, they are never both hot or both cold. [Furthermore, one of the two-way switches has to get a "hot feed"--an incoming wire to the circuit that is always willing and able to feed hot power. That comes from the breaker panel or is tapped off of an unswitched portion of a larger circuit. The other two-way switch has to connect to the "switched hot jumper".] Now it doesn't matter whether the travellers happen to run from light to light. That's irrelevant. They can just as well be pulled through the wall studs or under the floor or through the attic. In fact, they often are, depending on layout and distance. Their only job is to provide alternative paths between two switches. But wherever the wires actually run, the bottom line is this: You need four wires: a neutral which jumpers from light to light and is never switched, a switched hot which jumpers from light to light, and two travellers between the switches such that exactly one is hot at any time and exactly one is cold at any time regardless of whether the lights are on or off. Thus, each of these four wires has a state and function that is different from any other wire's state and function. So, no, if I've understood your question correctly, with ordinary wiring materials (no transporter beams or warp wires!), I think you'd need to use magic of some kind....See MoreTroubleshooting 3-way light switch wiring
Comments (2)What type of voltage tester were you using? Digital and non-contact testers can give false positives. A cheap circuit tester, the type with two leads and a small bulb, might work better for you. You'll usually find the incoming power to be a 2-conductor cable....See Moregreg_2015
