I've got a issue with my 12 volt system. I've checked all the fuses and breakers and all are good or in the right position. I then took the front panel off and checked the AC (120) coming into converter, I had power there. I then checked the power coming out of the converter and although it said I had 20 dc volts, I was using a cheap meter therefore think it was at least 13 volts. I ask my dealer if there was anything else that could keep all DC power from working and he said no. Said once it leaves the converter it goes through another set of fuses and it has it's on line going to each of those units. I just want to get another opinion. He didn't tell me about a battery kill switch (which I know shouldn't have anything to do with what I'm talking about) but if I didn't know about that switch maybe there is something else someone can tell me to check. I have a 2012 Wildwood with one slide. Thanks for the help
Get a new dealer. This is a common problem with an easy fix.
Since you did not put your model in your profile (or signature) I will assume it is a 5th wheel and you used "jacks" plural.
The DC system has two "feeds"; one from the converter and one from the battery. Between the two are resettable fuses (current limiters) that look like this photo. It has a button on the short side that will pop when overloaded. There should be one near the battery and one very close to the metal junction box that the cord to your truck goes into.
IF this current limiter opens (or becomes corroded to the point it becomes electrically open), the converter will power ALL DC items in your camper EXCEPT: Charge the battery, the main slides, and the front jacks (also called landing gear).
The battery will power those items until it dies. Test the battery by putting your meter on the battery terminals.
Pressing the monitor will tell you the battery is "full" ("C" on the monitor - for "charging") even though the battery is dead since it measures CAMPER voltage and not battery voltage. If you unplug, your camper should be dead (no lights on the monitor).
Look for one limiter under the pin box and another within 18 inches of the battery. It may or may not be covered with a red rubber cover.

Yes as Avid said jacks and slide are hard wired to the battery. Follow the positive cable until they connect to these mini-breakers in the photo. The little black button on the side is the reset, push the black button in. Hopefully this will solve your problem.

Wow...autocorrect...anyways..t his thread saved me a lot of troubles. On top of it all my battery went dead. I charged my battery and got the power back to the jacks and awning and slide...but as soon as I would unplug the camper...no lights or power off the battery at all. I couldn't figure it out as I am quite new to owning a camper. I am grateful for this forum and thank everyone for their insightful input and detailed posts. I really saved me a lot of trouble. I was ready to tow the thing to the dealer and it would have been weeks before I would have got it back. Thanks again!
