Bad 12V TV Outlet

Getting the trailer ready for the big trip this year so I bought a new television that is 12V native with built-in DVD player. Installed it today and discovered that the 12V plug behind it is dead. No power at all. The 12V plug in the bedroom has 12.2V and works perfectly. In checking the fuses at the WFCO Model WF-8955PEC converter I noticed that one of the 12V fuse slots has the red LED next to it on continuously. That slot is not labeled as any particular device just as 15 amp Option 2. Does the red LED indicate a short, or any other malfunction? I did put a meter across the pins and it showed 12V, however, when I install a fuse it blows immediately. I am assuming a short somewhere in that circuit. Any advice or suggestions are greatly appreciated.

The led glowing is indeed showing a blown fuse. You need to track down the short or overload. Did you try it with the TV unplugged? Does it blow when it is plugged in? Some of those lighter type connections don't match well and cause a short. Other than that, it's just trace the wire back to the fuse, or try to replace the wire.

Lynnmor,
Thanks for the info. My inclination is to try and chase the wire back to the fuse and see if I can find the problem since there is obviously a short and I don't want that LED on all of the time. I may be able to use the old wire to fish in the new wire. If that doesn't prove feasible I have the ability to run a new wire from the bedroom outlet to the TV plug and that is my second option. I believe that I will have to take the converter loose from the wall to see where the TV plug wire terminates, does that sound correct? Since everything else in the 12V system works I will disconnect the TV wire from the back of the converter to get the LED off, at the least.

Sounds like you are on the right track. I would disconnect the suspect wire and test it for a short to ground. Double check the outlet to see if the short is right there.
