No lights with 12 vdc

[biggie]

I purchased a 2006 rockwood 8280ss 5er today and without the camper I have no lights our any power in camper from battery. I have 12.5 volts at battery and at write coming off connecter under pin box. Slide works and leveling jacks work fine. I also have no voltage at the battery connections in the converter. Was just wondering if there was a switch I was missing somewhere? If not I'm assuming it is a broken wire between pin box and converter. I can imagine that will be fun trying to pull new wire through! Any suggestions are greatly appreciated.

One of the circuit breakers has tripped. The battery shut off is off.

Tried all breakers they are good along with all fuses by converter. Where is there a battery shut off?

Look in the photo for the current limiter (red rubber covered) under the pin box. The terminals can become corroded under that rubber cap.

Remove the cap. Remove the nuts that hold the terminals on and sand them lightly with wet-n-dry sandpaper.

If there is corrosion at the terminals no current will flow through the current limiter. It connects the battery and Tow Vehicle charging lines to the in-camper converter.

Isn't there a breaker on the tongue, or just behind the first crossmember under the trailer?

The OP mentioned "pin box" so I assumed it was a 5th wheel.

ahhh. Okay, is that what you call it on a fifth wheel?

I did have 12.5 volts right by connecter after the limiter

One time everything worked on my panel except I could not get any 12v lights inside or out. What I found was a loose neg. connection behind the panel, You should have about 8 wires "white" tied together with a twist connector, after I re twisted it all my 12v lighting worked

Hey, next time you're in there, try one of these.

Outback TBB-GROUND Ground Bus Bar



I'm not a big fan of wire nuts in vehicles, too much vibration. Not that it doesn't work, but a buss bar is easier, and you can add to it later with a lot less fuss.

Where does the wire go after that?

After that it goes up through the top of the pin box towards the bed but must go in between the two and then head back to converter then comes through the floor behind converter

So, from the posts I assume you do not plan on removing the terminals and clean them. Just because there is power on the POST; does not mean power is getting to the wire.

There was a little of the stripped wire showing after the connecter so I actually could get meter in there to test

If you tested the output on both sides with this method then it has to be the connection at the converter. There is nothing else from that current limiter to the converter that I am aware of.

Here is a generic wiring diagram for a 30TS camper. Good Luck.

I am guessing the wire got cut off by the slide out in order to have 12 volts after limiter and nothing going into converter. I am going to dig back into this after work in a couple hours. Thanks for the suggestions guys.

I=V/R

I is the current, and if nothing is flowing, your voltage could be pretty much the same on either side of the connections even when resistance approaches infinity.

I had 800 milli ohms on cable between the converter and current limiter. Had to get caught in the slide. Replaced the wire and just ran next to gas lines on bottom of camper and everything works fine.
