power to trailer battery

I just took delivery of my new 2010 Ford F250 . After driving it around for 500 miles , I hooked up to my Airstream to set up the hitch. I have a back up camera to aid in hook up, that is wired to male a 7 pin plug. Just the power to trailer batt. and ground lugs are used . It would not work because the power to the battery lug is dead. Anybody have a idea way it would be on a new truck ? Please help

On some new trucks you have to install a fuse or relay in the fuse panel under the hood to get the brakes and battery to work. The dealer usually supplies this with a pigtail for the brake controller if you purchased the tow package. Check inside the glove box.

Yep, check to see if the fuse is installed, and also remember that the ignition has to be in the run position to get power to the plug.

That pin should be hot whenever the key is on, no matter what is connected to the other 6. You need to check your Owner's Guide to make sure a fuse/relay isn't missing or blown.

Don't you have the integrated brake controller with the tow package?

Hi
Just talked with a good Ford Tech a few days ago and he said the contol module will not close the relay for the charge pin unless all the pins a connected. So I checked it with a meter at the trailer battery and he was correct . thanks for all the help, the problem is over.

I am now out on my first camping trip with it now, went 1200 mile and getting 10 miles to a gallon.
