View Full Version : DC Plugs have no Power (Its not the GFI)

I have no DC (battery) power to the trailers plug outlets inside or outside of my 2013 Bullet.

I tested the power to the GFI plug and there is none, so its not the GFI cause there is no power getting to it.

I have AC power for everything in the trailer.

I have DC power to the lights and a few other things.

At the fuse panel, I have DC power to only a few fuses it seems. I pulled all 10 fuses at one time and only a couple red LED lite up (i.e., the stereo, which works on DC). The majority of the other DC fuse spots, don't lite up the little LED light. when the fuse was pulled.

I don't see any inline fuses.

The whole underneath of the unit is closed off and would be a B!T@CH to remove and investigate if that is where the wires run.

Help!

There are two "entirely different" power systems in all travel trailers. When plugged into shower power, the "conventional electrical outlets" (like the ones in your home) are powered to provide 120VAC. When you are unplugged from shore power, those outlets are "dead" and do not provide power.

The 12VDC system (battery power) provides power to the lights, some "cigarette lighter type" outlets, the radio, furnace fan, refrigerator ignition/monitoring system and to the water heater ignition system. The battery/12VDC power source does not provide any power to the "household outlets" in the trailer and there is no 120VAC capability when not connected to shore power.

Shore power can be provided by a "household outlet", a "campground pedestal", a "generator" or an "inverter". Shore power is not provided by a battery and the two systems are independent of each other.

So, based on your description, if you are not plugged into shore power, none of the outlets have power to them. This is normal.

Is that what you're describing? If it is, then your system is operating properly. Each of the fuse LED indicators "should light" if the fuse is pulled, but if you pull the fuse that powers the panel, then none of the LED indicators will illuminate. Pulling ALL of the fuses, most likely, disables the "LED indicator system" so your observation that some don't light, may be normal as well, if you've pulled the fuse that powers the "WFCO power center"....

I'm unsure of what you're asking, but if you plug your trailer into shore power and the outlets work, and if you pull each fuse "one at a time" and the LED indicators illuminate, then the system is working normally.

I totally agree that you will NEVER have DC (battery) power to any outlet & you are correct , it won't be the GFCI, it has nothing to do with DC voltage. Once you plug in to shore power & still don't have AC power then you may have problems. Did you remove the GFCI plug or just test it from the front? Need to pull the cheapo plug & inspect the wires that are just pressed into it, they can become loose from vibration or arc & not make contact.
Plug it into shore power, be sure your battery disconnect is on, check battery voltage before connecting to shore power & then check back in here for more information. At this point I can't tell if you have shore power issues or dead batteries.

The answer to your question is yes: if you disconnect everything nothing will work. This is perfectly normal.
