Charging the Camper Battery
I've got an 2004 F350 SC Diesel with the factory wired 7 pin plug at the bumper. During a recent camping trip I spoke with a buddy about the battery in the camper charging. He said that as long as I was hooked up to the factory system my truck would charge the camper batt. Any way of checking this theory?
Thanks in advance

not so fast
On my 2001 ,fuse box under the hood, on the right side of it takes a fuse and on the side of that takes another. Some trucks come with them and some don`t. Your brake controller should tell you if you are puttin out juice. I believe one fuse is for brakes while the other is for power.

Very knowledgeable
You can check to see if your battery is being charged when towing: With the trailer plug disconnected measure the battery voltage. (The AC power must be disconnected also). Using a voltmeter, check the battery voltage - it will usually no more than 12.5 volts, or lower, depending on charge. Now, connect the plug to the tow vehicle and start the engine. The battery voltage should now read at least 13 volts, usually closer to 14. If the voltage doesn't change, the tow vehicle is not charging the battery.
You can check the onboard inverter/charger in the same way: With trailer unplugged from tow vehicle and AC, read battery voltage. (12.5 or less).Then plug the AC power cable in - the voltage should again increase as before. If not, inverter/charger is bad or disconnected, whatever.

check the 7 way plug of the truck first to see if your getting about 14.2 v with the engine running if not check the fuse box under the hood d/s there should be a fuse for the trailer tow line, if the truck turns out to be ok move on to the camper best place is to check to make sure you have all batt disconnects turned on , then check what your voltage is at the batterys before turning on the truck then check to see what it is after post what you find
