Battery Issues, Connections?

Question

I took my TT in for an A/c Issue and they put in a new 1300 A/C.  I have a new Rockport with a 1500 and a 1300 A/c.  Problem is my hitch jack no longer works unless I'm plugged into the truck or shore power.  I had the trailer plugged in since I cam home so I figured it was getting a trickle charge.  The dealer must have unhooked something when he changed out the A/C unit.  I thought it was a dead battery but I put a meter on it and the battery is fully charged. I can't reach him today because they are closed but will call him as soon as they are open.  Any ideal where I should start looking?

I had some electrical problems and found that the connections to the wires from my batteries to my converter has come loose. I had to get new crimpers and re-crimp the cables. Both the ground and one of my positive cables had come loose.

Hitch jack should come right off battery.My first guess is they disconnected the battery, then dropped a wire when they reconnected.

Ha!  I just looked under my butane tanks where the battery cables were headed and found a large switch , On/Off for Battery.  I turned the switch to On and guess what?  My hitch now works.  You are correct and I guess I'm still a novice.

GUESS #1they disconnected the house batteries when the worked on the A/C (instructions say to do that though no technician I know actually does, myself included and yes I'm a certified electronics electrician. I so disconnect batteries on SOME stuff like Inverters)And they missed a wire re-connecting.
