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?
Here are pictures of the other black to white multimeter readings.
The 01.9 will reduce to 0.7 if I hold it there a while.
