Ok first make sure you have 12 volts at the battery, if that's good then look at the starter and have it check to make sure its in working condition, if the starter is good have the alternator load tested.

you should charge the batt. newer vehicles don't like the power surges from giving jumps , surprised the jeep didn't blow something , I think you have a wire shorting out somewhere better take a closer look
