Swapped light switches for hallway lights. Only works with the switches in certain positions.
I am replacing old rocker switches with decorator 3-way switches. On each end are a trio of wires (pictured). I wired them how I remember them on the old switches. I know I should have taken a picture. The lights only turn on with the switches on specific positions. I tried using a multimeter tool to determine which wire is the hot but I get no reading (multimeter confirmed working in an outlet nearby).
Any suggestions would be helpful. I’m a new homeowner new to electrical work.
