Identifying TV Cable Out/Inlets

Is there an easy/non sophisticated way to find out which cables goes where?

Example, something to hook into an external port that would energize the cable and then go inside to test outlets to see which ones are energized?

    Attach the cable to an outlet, attach the alligator clip between the core conductor and the shell nut. Go to other locations and use Ohm meter probing the center to the out side of the connector. You will see the short when you find the correct cable.


    Thanks, I don't know why I didn't think of that. :S
    And you may see the short on several different coaxes if they are connected somehow like the batwing panel or AV switches, etc. So be sure that you are isolating to the same coax. Also I'm not use how this technique will work if a splitter is connected which is common in RVs.

  • I use a 9 volt battery I connected a piece of coaxial cable to. Connect it and stick the tip of my tonged on the other ends... Zappp! this one, works every time. lol
