newbie electric system question

[massatari]

HI,, I have an 05 Fleetwood Bayside.  I opened my popup yesterday.. when I turned on the electric I could faintly hear the lp detector going,, which was odd because I didn't touch the lp tank at all.   SO,  checked the fuse box there was a 15a fuse blown.. I replaced that. plugged in to the house ac and the lp detector was going off full volume. I uplugged EVERYTHING now.. basically I determined that when I plug in anything to one particular 12vdc miniplug I can set the lp detector off.  the other miniplugs are fine. its just occuring for just this one.
Any idea what might be happening here?  
Thanks!
Shawn

You probably left your battery connected for an extended period while the pop-up was unplugged.  The LP detector, which will alarm if the battery voltage gets too low, will also drain the battery over time.  You heard it trying to go off, but there just wasn't enough left in the battery.

Try letting the battery charge overnight, then see if it still has a problem with that plug.  If it still sets off the LP detector, the 12VDC plug may have a problem.
