| This is advanced wiring for electrical experts who really know their stuff! And even then it can take quite a bit of study, tracing wires, and testing to figure out what each wire and connection is for.
Modern romex wiring is somewhat easy for an electrician to figure out because you have bundled colored wires and wire nuts. Everything runs in a logical manner - point A to point B. Also easy to disconnect a wire nut and trace out a circuit.
But K & T can be "spaghetti"! You may have 3 or 5 wires all the same color running next to each other. Sometimes just 1 wire running by itself! Huh? 1 wire? What are they doing here??? Then the splices are impossible to disconnect for testing. They wrap around like a spring.
Then homes with K & T have been around for a long time. There may have been additions - things added and removed. I've found wires spliced into other wires, then follow these wires to a dead end. Just cut wires which were taped and left hanging in the wall or ceiling. (You find this stuff when you tear out the walls.)
So I think it would be quite difficult or next to impossible for someone to try to help you figure out your old wiring via the internet.
You would basically need to make a circuit diagram of your existing wiring. What all goes to what. Then it would become clear. But you might have to tear out your walls to find what all goes where.
Actually a similar problem is with electronic circuit boards. There will be one copper connection on a circuit board which connects to 6 different things. You can't easily disconnect things to test each individual thing.  |
