This is on the SIII - so neg. earth and alternator. The back story: Saturday I left the lights on overnight, so the battery was totally flat Sunday morning. I used one of those jump start boxes to get it running, drove around for about 15 minutes and left it idling for another 15 or so.
This morning, just enough juice to click the solenoid so I figure I didn't let it charge enough the day before. Used the jump start again, got running and headed in to work. After about 30 minutes or so of running fine, I was idling at a light and it just stopped running.
I tried the jumper box again, but nothing this time. Its acting like the battery is completely flat: not even a dim glow from the lights, etc. Acts the same with the jumper box giving it juice.
My first thought is my who knows how old battery has given up the ghost. I've heard tales of those jumper boxes damaging older batteries. Other than that, any ideas what else it could be? I know it could be a short of some kind somewhere else, but that seems like an awful coincidence in timing if it is. Is there anything about the alternator that could cause this? It seems like even if the alt was dead, having juice from the jumper would at least work the lights.
Thanks as always
