Using a continuity tester check continuity between the common black terminal and each of the traveler terminals. 3 install the first. Test a 3 way switch turn off power to the switches at the circuit breaker and using a tester make sure power is off. In this step you will be turning the power back on do not touch any of the wires previously removed with. In this case the traveler wire and load wire were swapped and repairing the circuit involved switching them back.
2 turn the power back on. In the former case you may simply have a miswiring issue. Now using your multimeter you are going to determine which of the three colored wires is. Turn off the power at the circuit breaker remove the 3 wires from each of the switches and make sure that none. There should be continuity between the. There are a pair of wires that run between the two switches.
Three way switches work by alternating the power connection between 2 legs called travelers. Remove the two 3 way. 1 turn off the power to the circuit at the main panel.
