adding a charging line

Hey all..
i was wondering if you would be able to help me. ive taken my trailer out the last couple of weekends and noticed my batteries are dead. i thought i had a charging line in place to charge them when i was traveling. my question is, how hard would it be to wire a charging line in place? is it just a simple line going to the positive terminals? is there a fuse that needs to be added? i have a 7 way connection on my truck, but im not sure if it has a wire already in place. is there anyone that can basically walk me through adding in the charging line, or can point me in the right direction to get the information?

On pin #4 of your 7 pin connector you should have 12 volts when ignition is on. Then make sure pin #4 on TT connector is connected to positive terminal of battery. There should be a fuse at TT battery. Once you know vehicle plug has voltage connect to TT. With engine off measure voltage. Start engine you should see an increase in voltage at the TT battery indicating it is charging.

Should already be in place. Check your 7 pin to see if you have 12VDC present. There will be a fuse on the trailer that might be open(blown). Download the Bargman wiring diagram from the internet for the proper plug wiring sequence.

What is your TV? If it is a GM variant then everything is here, but you do need to add the fuse, and on newer ones connect the wire.
