Solve this problem first,and get a charge on the battery,then lets look at the jack.
I still question the high convertor output voltage having had a runaway convertor cook my batteries but that a secondary question at the moment.
I talked to a engr. at progressive dynamice inc. makers of the intelipower
here in Michigan, I ask him if it would be alright to run another set of wires from the converter to the battery, he said that it would be ok, tryed it, and eveything seems to be workng ok, this is the first I heard anything coming from the converter, the little fan is working and the converter feels warm like its working, volt reading from the converter is 14.3v and the battery is reading the same, battery showing full charge. The tongue jack works when connected to shore power and when disconnect from shore power, ran the wire from tongue jack to where the bargman connects to trailer.
