I purchased a residence and the basement became gutted and i am trying to rewire the 3 manner activate the basement stairs, despite the fact that i cannot discover any diagram that comes close to the prevailing wiring this is setup. In case you wire it like this and it would not paintings, then there is probably something wrong with the three-wire cable, disconnect the entirety from the three-cord and test all the wires for continuity. Make certain all of the cord-nut connections are tight - this is in which i have the maximum hassle in my residence. What i've is a light switch at the top of the stairs that has energy entering it. From that transfer it then has a three wire jogging up to a mild above the switch, which has by no means worked because i purchased the house.
Edit: so after reading extra up on three manner switches i may think i understand how they initially stressed it although, i just have not seen any diagrams executed this manner. It looks like they passed the 2 tourist strains through the primary light and then to the second transfer then the strength would be coming from the second transfer to the opposite lighting. Not sure if this is correct however maybe a person can shed some light on it as i haven't visible it accomplished like this.
