Whats wrong with my jeep wrangler, im sorry its long but please read and help
okay so this problem started out when i left the lights on, the jeep died. I jumped it off and when i unhooked the cables it bogged off, i thought this was because i didnt leave it hooked up long enough so i hooked it back up, let it sit a minute, started it, unhooked the cables and it bogged off again. so the next time i jumped it i kept it at about 2500 rpms and had my friend unhook it, it was running fine then when i let it idle it bogged off again. i bought a new battery and hooked it up and started it and it was fine. a few days later i was driving and the check gauges light came on and the alternator gauge dropped all the way. so i put it in neutral and it was idling fine. i figured it was the altenator so i took it out and had it tested at autozone but it passed, 2wice. i figured it was just the wires so i cleaned all the connections and hooked it back up and it was fine for a few days then it did the same thing. i just ignored it. the other day i was pumping gas and i went to start it and the battery was dead. i got a jump and drove home with the alt gauge still dropped, and when i tried to start it again it wouldnt. i have no clue what the promblem could possibly be so any help wound be greatly appriciated.
