I have a error read out on my controller for a zone, which is not working. I recently got a new greenlee wire locator and have had great luck using it to find shorts and valves for repair. however, on this job i have issues as the utilities are interfering so much i lose track of my wire, and cant pick up the signal again past this large area of utilities underground. I am not sure, there could be a short or cut wire if they rain new utilities( have not asked this question, but doesnt look to be any new lines run). any suggestions for this type of situation? Thanks guys.
