My brother-in law pulled in some direct burial cable to his well a couple of months ago, about 1500' to the well. The pumped stopped running and he thought it went out, but checked and he had 97 volts instead of 230 V. He apparently has two of the conductors 'leaking' - he says there is about a 4 on his continuity tester. Is there any instrument that helps find an underground location of a bad insulation spot? He would like to repair it instead of pulling it all out again - said it was really tough - I don't know what kind of wire it was (I do commercial) he calls it quadraplex (I get) but direct burial, but he pulled it in PVC. He is about 300 miles from me.
Thanks.
