lately, it's been one thing after another with my 96 sunfire. 1st, my trans, then my fuel filter was plugged. now my battery light came on. On my way home from work, I saw my battery light come on while sitting in traffic for maybe 3 seconds. Then it turned off and didn't come back on for the rest of the 8 mile drive home. The car drove normally. When I came home, I checked the battery terminals to make sure they are on tight, since I had them off two days ago to change my fuel filter. They were tight with no corrosion present. My Duralast battery is almost 1 year old. My alternator is a duralast alternator that I bought new back in 2001. I put a black and decker charger that plugs through the cigarette lighter. It's still charging the battery after an hour which is unusual. It seems to me that it's most likely the alternator, but I just drove 5.5 hours all highway last thursday, the battery should be charged. I had the battery unhooked on sat-sunday to change my fuel filter. Pretty obvious to test the alternator and battery? am I missing something?
