Having trouble with a 3-way switch replacement bank. Left two don’t work, far right does.
Far left also “worked” intermittently but now nothing, Other switch for that light bank does not work either I clearly the circuit is not correct.
I *thought* the wires were wired all the same with the colors, but obviously something is wrong.
All switches are 3-way and wired the same way:
Upper left red, lower left black, lower right white. No ground wire available.
