I have a GFCI in the garage that tripped and keeps tripping. I traced it to an outlet in the basement but there is something weird going on. I’m not an electrician, but I’ve done a bit of wiring, but I don’t know how to interpret this.
In the picture is the basement outlet pulled apart and the power is on and the GFCI is reset and working. This basement outlet has 3 14/2 cables coming in. I think one is power from the garage, and the other two lead to outlets outside the house. I checked the wires until I found 120V and then marked them with yellow tape, which is what is shown in the image.
However, if I connect the multimeter to the black/yellow and one of the other whites I get a reading of 101.8, and the other white reads 0.7. This shouldn’t be happening, right?
I really have to go to bed so I only made it halfway, but I appreciate you taking the time out to explain your craft and standards in your field. I will make a strong effort to finish in the morning, but thank you either way, stranger.
