To Joe D
I've been working on 100 plus year old houses for over 30 years. That was just a list of some of the things I find everyday with houses so old there's no ground.
Well I found the solution to my problem. I changed the electrical outlet on one of my outlets. It looked like the wires were a bit burnt. This solved the rest of the circuit problem.
In your new post you said black wire"s". There should be one wire to one screw and as was suggested remove the little joinner between the screws that have red and black wires.
Can anyone help, when buying a old house if all outlets are two prong and there is no ground wire lead there, how do you change them to the three prong outlets? Do I have to add a ground wire some how??
Odd question here. Is your house piped? Some older homes in the past have been piped. My house is 50+ years old and I piped her!
