4-way HELP


I have three switches two lights. Each switch will turn on and off the lights, provided that they are already on... hence I have the problem that if they're off only one of the mystery switches will turn them back on so something is wrong here…



Any guidance anyone could provide would be greatly appreciated. Attached you'll find a way out at each one of the three switches.

R=red
W=white
B=black

Any combo of the above circled means that the wires are tied together in the box.

Re: 4-way HELP


Need to know which terminal on each 3-way switch is the common and also which cables in the 4-way switch go where. Pictures of the interior of the 4-way box will help.

Re: 4-way HELP


The above drawing has more wires in each box than the OP has so it is not correct.
I think the light might be tapped in at the four way switch. If that is true then the RED needs to be on the common screw at the three way switches. Common is the black screw.

We also need to know all the wire connections at the lights solve this.
Probably why the OP's lights dont work...

Re: 4-way HELP


I believe this is what you have except that the use of the black and red wires is swapped between the switches. The switch loop from the light is connected to the reds instead of the blacks.

Re: 4-way HELP


The drawing I see that you submitted has the light connected to one of the three way switches not the four way.

It would work being fed from ANY of the switches.

Re: 4-way HELP


Yes but based on the wires in the boxes submitted by the OP, his setup has the light connected at the four way.

And without knowing which screw is the common it is clear to me that one of the three ways is wrong for sure, based on the position of the colours. They should be wired the same.

Re: 4-way HELP


TB....

1) Look in the boxes.... and tell us what wires are in each box IN ADDITION to what wires are attached to the switch..... you will see a wire nut with most likely two wires spliced/joined... tell us the colors.

2) Tell us which mystery switch turns on the lights..... and does it regardless of the position of the other 2 switches.

TIA

Is a bit more details on the switches I'll gather the which wires are connected to what screws in a bit.

All three light switches in the down/off position lights are on each of the three light switches will now turn the lights off when put up and on when down.

Switch one in the up position lights are off no other switch turns them on.

Re: 4-way HELP


As someone pointed out in another thread, don't rely on terminal position/location. Traveler terminals will be the same color and are functionally interchangeable. The "common" terminal will be darker.

At #7 , the OP wrote (referring to the diagram posted by joed)

This is not so, since in his usage Red and Black have been transposed.

While this would work if it was so connected, going back to the OP's original "diagram", it seems to me that, on switch Three (on the right), the Red and Black wires have been connected to the wrong terminals and their connections should be reversed.

Re: 4-way HELP


@FrodoOne That was not the op that responded.

Here is a colour correct drawing of what I believe @tb582 has

4-way HELP-four-way.jpg

One of his three ways is definitely wrong. They both should be wired the same. The position of the common may not be as pictured since different manufactures sometimes put them in different positions. You need to make sure the red wire is on the black screw. The black screw is the common no matter what position it is.
