is the greenlee line voltage or cat5/6 type, as the ideal one? I've heard seen a Tic Tracer but cannot remember if it found wire/cable on live or dead circuits, my understanding of the TDR unit, by JTE is that it gives you total short length, so if it reads 25 feet then the short is 12.5 feet away, what I believe I'm looking for is a melted section of wire, in a box or in a wall but cant seem to get toner to ring out of cable? The red conductor still works the lights, i always get a load type continuity ring on my greenlee volcon, and the black non-working conductor rings constant continuity indicating a short....didnt have a regular volt/ohm meter on test day...and this flu isnt helping either, what sort of reading should I be getting on the downstream conductors with the black red white disconnected from panel, but green and jacket still bonded?
