I have a 4 gang switch box with one 3-way switch and three single pole switches. When the 3-way is flipped on, all the other switches can turn their lights on and off. But when the 3-way is flipped off, none of them work.
I have them wired the same way as a 2 gang switch box with two 3-ways in it that work independently of each other.
All the white wires are tied together. The red from the 12-3 goes to the 3-way switch. The black from the incoming power pigtails to all 4 switches, and the black from each fixture goes to each respective switch.
What is wrong? Can I run three single pole switches and one 3-way off the same power source?? I covered up my walls...
