    Not knowing what wires you have it is impossible to answer your question other than to say none of the wires on a 4-way are a constant hot.

    gotcha- are any wires on the 3 way constant hot?
    this is a middle run box...
    feed comes into first box has this 3 way and a 4 way, then this box has the 3way a 4 way and a single then this 3way goes to the light......

    The only place you can obtain power for another circuit is from the common (sometimes a black screw) on the 3 way in the first box. And, the neutral from the same cable as the hot.

    You will need to test the common screw on the 3-ways with a meter or test light. One will have a constant regardless of the switch position, the other will be hot only when the light is turned on. You will still need a neutral to what ever the new switch is feeding.

    ok- so here it is........................
    got it on above box feed here is the next delema. so the final box with the 4 way switch I am trying to get a feed out of for an outside light...... so I grabbed the wire and hooked it up and it works.... when the 3 way switch in the box prior is on the ext light doesn't work- 3 way off ext light is on?

    question- can I feed a light from a 4way? the 4 way circuit is this..... feed to switch1, switch 1 to switch2, switch2 to switch3, switch3 to light. I want to pull a feed off switch3

    No. A 4-way switch only has travelers attached to it. See if this helps


    The only place in this picture that you can pick up a Hot and a Neutral is at SW1

    The final switch must be a 3W if it feeds the light.

    And, any single screw, on it, will have power only when all the other switches are switched a certain way, as you've already discovered. Sorry.

    looks like I will pull a feed up from the receptacle below the switch for the outside light.....................
