How to re-wire 3 way switches. Every few decades I need to re-learn this. This is a reference VJO for our future selves.
1. Breaker off
2. Remove both switches
3. Physically separate wires that were connected to switches
4. Breaker on
5. Locate "Hot" wire; 120Volts, mark wire and label box "A"
6. Breaker off
7. Box "A" wire all 3 wires together
8. Breaker on
9. Box "B" locate both "Traveler" wires that have 120Volts. Mark both "Traveler" wires.
10. Box "B" wire with no voltage is "Load". Mark wire.
11. Breaker off
12. Connect "Hot" in box "A" to "common" terminal of switch
13. Connect "Load" in box "B" to "common" terminal of switch
14. Connect both "Traveler" wires to remaining terminals of switch "A" and "B"; one wire in each terminal
15. Tug test all wire connections to ensure they are properly installed
16. Breaker on and test
17. Step back, invoke the magic words "Another job, well... Done!" and give yourself a pat on the back.

More rigorous test of oily rags catching on fire:
-Toxic amounts of phenol at low temperature 230F - 110C
-Can take a long time, depends on ambient temp. 24-36 hrs at 60F - 15C.
-Carbon Monoxide may aid ignition
-Cotton faster than paper.
-Prodigious amounts of smoke prior to ignition
