I ran a wire from the garage to the corner post of a vinyl fence and made an internal splice in the post. I spliced it to another 12-2 wire that runs underground about 60' to a flower garden.
I have a switch in the garage with power off of a GFCI receptacle. Flip the switch and the GFCI trips.
I have isolated it from the power. Testing the white and ground with a continuity I have continuity. I know I have a short. Weather, back surgery and a mud spot by the post have stopped me from checking the splice in the post.
What tool is necessary to locate a problem in the ground (hopefully its in the post splice)? Really wanted to know when I test continuity on the black and ground I get a slight movement with the needle.
