I have a three-way switch that was wired in the configuration shown below. The switch with the load wire to the light is fully functional. however, whenever the other switch is positioned down it instantly trips the breaker. I have inspected all wires in the box for any visible damage, and tested if it still happens when all wires are separated.
I have a concern that maybe the 14-3 (specifically maybe the traveler?) that was ran may have been damaged during construction, but I do not know how to test for that with a multimeter.
