4-way wiring with dimmer
Sorry if this question has been asked before, but I couldn't find the answer
I have what I think is a 4-way set up. One switch that I will call a master (a regular pole switch that is always on) another pole switch that is used to control the lights that I will call a slave, and my problem switch that is a dimmer switch that has a toggle button on the bottom of the switch. The dimmer is my problem, because it recently failed. I bought a new dimmer switch and the wires are not the same color as the old switch. I have a tester that I used on the the 4 wires coming out of the dimmer box and no matter what position the other two switches are in, one black and one red wire coming out of the box are always hot. The other black wire is always not hot or has no power to it. I am trying to determine which is my Hot wire and which two wires are the travelers.
