Burnt instrument panel on backside

Hey guys, I had the alternator checked AT our local rebuilder, IT checked o.k.,we loaded hard and it stayed in range. ( sorry I forgot to add that to my post),this is the only damage, I checked complete harness, under hood and dash and it all looks great, I can't even find overheated insulation, I will post more pics tomorrow, I have seen batteries do some weird things so I'm gonna buy a battery, then start checking grounds and voltage through out harness, my daughter told me she was coming down the highway and everything was o.k. and working, then all at once smoke came out of dash and died, I will check Ebay for one. Thank you gentlemen for your help and I will post more pics tomorrow. THANKS AGAIN GUYS. I JUST WANTED TO SAY THAT ALL OF Y'ALL ARE GREAT AND HAVE A KICK BUTT MOPAR OR NO CAR WEBSITE!!!!!!!
