Hi,
I have a 2003 accord ex 4 cyl. I was driving on the freeway when the gauges all bottomed out. Then they came back & forth & finally engine quit. I towed it. Replaced the Alt, tensioner & belt. The alt seemed to be very hot. I went to remove the battery & the positive post started pulling out of the battery. I replaced the battery with a good used one I had around. It now starts fine, but the battery light is still on. Testing at the battery I get a reading range from 13.63 - 13.81 depending on what accessories are running. The only code I get is for an O2 sensor. Does anyone have any ideas?

Thanks, Tim
