I am putting up new cabinets and in the process moved a 4 way switch and broke it while removing the wires. I bought a new one. Now I think I may have put a cabinet screw through the wiring leading to the 4 way or have it hooked up wrong. I would like to test the circuit but do not have any meters. Can I test the circuit in the following manner? If I remove the switch and wirenut the red to red and the black to black will the other 3 way switches then work the circuit? Then I should be able to figure out if the 4 way switch is broken or if I did indeed put a screw through a wire somewhere near the junction box. BTW, the circuit breaker never went off, that is why I suspect either the switch is bad or I have it hooked up wrong. I placed the red wires at the top two terminals (1 and 2) and the black wires at the bottom (3 and 4). The ground is also at the bottom of the switch. Thanks.
