Hello. My name is ***** ***** I will be helping you today.

What kind of trouble are you having?>

Customer: replied 1 year ago.
I am trying to find out why I have no power to the Battery/Auxiliary connection for my trailer wiring on my 2003 F250 and what I have to do to get power to it. I have a trailer with an electric jack that should be powered by this connection.

I don't know if it matters, but my truck is 6.0 L diesel.
Expert:  Wayne Crawford replied 1 year ago.

Check the 20 amp fuse 115 on the interior fuse box both for being good and having power to it. Let me know what you get.

Customer: replied 1 year ago.
There is power to the fuse, but the fuse does not have continuity, so I need to get a new fuse and confirm that fixes the problem.
Expert:  Wayne Crawford replied 1 year ago.

Correct. Start there. Also that circuit doesnt carry enough amperage to run your trailer jack directly.. that circuit is for charging an auxiliary battery on the trailer that then runs your jack. If your trailer doesnt have its own battery you will likely blow that fuse again when you try to use the jack.
