A friend was trying to help me install new dimmer switches and instead of disconnecting one wire and putting it on the new switch, he just cut the wires and couldn't figure out how to put them back.
I used my multimeter to find which wire was which and got the three way switch to work, however next to my three way switch I also have a single pole switch for the lights above my sink. Now, that switch alternates with the three way switch. One set of lights goes on, and the other goes off. If the switch by the garage is off the lights above the sink won't work. I think I have the traveler wires reverse??
