    Wiring 3 way dimmer
    Changed 2 switches on a 3 way circuit for one light. 1 is a master and 2 is a slave.
    One box had 2 blue wires and 1 red wire. The other box had 2 blue and 1 yellow.
    Connected the blues on 1 as run through and red to black(master). The other connected 1 blue as run through and blue+yellow to other run through(slave). Turned breaker back on and light fluctuates and dims by itself. Thought I had it right but have never done this before so not sure. Turned breaker off immediately to think about it. Any suggestions?
    Thanks

    The 2 blues are your travellers and go to same color screws on both switchs, The red at one end and the yellow at the other end, go to the dark screw. Flip both switches to opposite positions from when light is dim. If comfortable with electricity, you could jump across
    Three way switches to determine bad contacts inside switch.
    Also the bulb socket, or loose wire may be a problem.

    After looking at my wiring I think maybe it's the slave. Im using a cooper smart dimmer remote remote. Box has 2 blues and 1 yellow. Remote has 2 blues and green. Green is grounded to box. Wired 1 blue from box to blue from remote(no screws, just wires coming out of remote). Other blue and yellow from box I wired together to other blue from remote.
    Is this wrong?

    Here are the wiring diagrams for both the master and slave (accessory).

    Tk... did you notice the dimmers don't attach to the neutral anywhere? Yet they are electronic dimmers with LED lights. Do you suppose they use the ground for a return for that? I know the amount of power to run the electronics would be minuscule, but still...

    Or am I missing something there? Like maybe they are using the circuit to the light?

    The LED could be in series with the circuit, as well as using the ground, as electronics often use the equipment ground as a reference.

    The unit is UL listed, therefore using the ground as a reference/return is allowed.
