Wiring Problem

[Nas31]

Hi All,

Got a weird one for you, hope I can explain..

We had our 2001 Forest River Sierra 27FKSS plugged in at the house on a daily basis throught the week. One night when we got home we noticed all the marker lights were on.... Really confused since my understanding was the marker and tail lights only came on when the towing harness was plugged into the truck.
So I unplugged it, the lights were still on, so I unhooked the battery, then they went off. I am still unable to have the battery hooked up or plugged in without the marker and taillights being on. I can only assume its a short, but I don't even know where to start?? Do I have to disassemble have the trailer to find it???

Thanks,

Check out the 7 pin Bargman connector here: http://www.hitchntrailer.com/pages/elect.html

Make sure someone hasn't played a trick on you and run a jumper between the 12 volt and maker light prongs.......I have been known to do that to newbie unsuspecting camping partners.

If that is not the case, then you probalby have a short between those 2 wires.

As Chap said, the 7-way is the place to start. I've heard of the 7-way shorting several times. I've even had to replace mine.
