Outdoor wiring short
Is there a way to locate a short in a wire? My lamppost light is connected to an outdoor GFCI outlet. Recently the outlet tripped and will not stay on. I disconnected everything at the outlet and the light and tested with an ohmmeter. There is a partial short between the black wire and ground. The wire looks in pretty good condition. I've done wiring for many years and have never found a short in the actual cable - always at a connection. No one was digging in the vicinity of the cable. It's possible that someone years ago cut the cable to install flower bed lights but I haven't seen any. Are there devices to detect electrical leakages? I really hate to have to dig up the lawn and go under sidewalks to replace the cable. Any suggestions?
