Three Way Switch Not Working. Turn off power to the switches at the circuit breaker and using a tester, make sure power is off. Understanding how the circuit works satisfies curiosity.
However, a Switch System cannot be connected to two separate switches. Your pictures are of Three way switches, the black screw is your common terminal. I need to connect two-way using the same family of switch to two different circuits.
They are not the same as a regular switch at all.
Exterior Lights Switch - ON/OFF: this one I assumed was the same, and mapped it to the warthog exterior Are you using dual pole or a true three pole switch?
It has two humbucker pickups also. I thought only one should be hot??? I noticed the bridge pickup I hope that's all it is.
