stupid me, can't change a battery?

Today, on my '01 ram I put the battery terminals on the wrong posts. :banghead:..It's okay if the site moderator feels I should be shunned and kicked out of FABO. :violent1: I put the battery in the tray...it was identical to the one I just removed....except the terminals were on oposite sides ( red top OPTIMA) :fucyc:. First clue shouldve been the cable ends are different sizes. Probably to keep smart people from switching them, but I'm an idiot so it didnt stop me from forcing it on. :bootysha: I had to replace multiple fuses, but the radio is cooked and the air compressor won't kick on. I even swapped around relays with known working ones but to no avail. Any ideas on what I ruined on the compressor area? Hey, I'm in Phoenix and this heat sucks What can an idiot like myself look for to fix this? I promise to stop and think before touching any of my other Mopars. :prayer:
