Dodge Ram Charging Line

Hello,

Have a question about my 2013 Dodge Ram.

I have the tow package, which according to my salesman and the service manager, has a charging line to the 7 pin connector to charge the battery on my TT.

I'm not getting a charge, so I asked about it last week while I had the truck in for an oil change...service manager looked at it and told me it was a blown fuse, but they didn't have the correct replacement size. I told him no problem, I'd just swing into an auto parts store and grab one...which I did yesterday. As I was removing the old fuse, I thought to myself "boy, this doesn't look blown" but I figured I'd replace it anyway in case it was blown and just not visible. Much to my chagrin, the new fuse did not correct my problem. Now, I'm leaving on about an 800 mile trip with the TT and have no battery charging from the TV. Of course, the dealer can't get me in until a week from tomorrow. What can I troubleshoot on my own to get this charge line working? Any suggestions? Thanks!

Oh, also, for anyone uber-familiar with the 2013 Dodge Ram, I have the large in dash touch screen that the back up cam uses, but no back up cam. is this something I can likely add inexpensively? Is there an aftermarket cam that would hook into my display?

Thanks again.

  • Not sure about Ram Trucks (Split from Dodge in 2009),but did you have the key on when you checked for voltage? Are you checking the correct pin?

    My 2010 Ford has the fuse plus a relay in that circuit. The ignition key has to be on before charge voltages goes back to the trailer battery. Don't know if Dodge does it this way or not...

    Both the FUSE and the RELAY is in the same up front fuse panel. My manual calls both of these items TRAILER TOW...

    When I first got my 2010 Ford truck both this fuse and the relay was in a unmarked plastic zip bag in the glove box with no instruction as to what they were for.

  • What 2013 model do you have? Are you saying you have the 8.4 Uconnect big screen in dash information/radio set up? Did your truck come with the back up camera and back up sensors?


    Might need more information...Sounds like something may have to be re-wired in your connector on your truck, or the one coming from your rv to charge your battery. One would think that your Ram/Chrysler dealer would have schematic for the connector on the truck to see which wire, if any, charges your battery..it would help with a re-wire.
