I bought a residence and the basement became gutted and i am seeking to rewire the three manner switch on the basement stairs, although i can not locate any diagram that comes near the existing wiring this is setup. In case you cord it like this and it would not paintings, then there is probably some thing wrong with the three-wire cable, disconnect the entirety from the 3-twine and test all of the wires for continuity. Ensure all the cord-nut connections are tight - this is where i have the most problem in my residence. Believe junction field 2 did now not exist. Move returned into in paint, select the white brush and dispose of everything regarding junction container 2 together with the 3 wires. That looks as if a commonplace -switch configuration the use of three-way switches and the lamp inside the center. You ought to have located that on any of your internet searches. Black and purple are the messengers, and the white from junction field 1 is the no longer neutral, but switched "hot" (which have to be marked as such with a band of black electric tape close to each give up, however nevermind that) coming back from the farther switch to the lamp. The white from the primary transfer to the lamp is the actual neutral.
