Last weekend got in the car and the battery light was on, the gauge was below the normal 14 volts, and it said battery not charging. Ok, so my first thought is alternator. Get out the multimeter, check the batter, it's only getting about 12 volts. So, alternator, right?
Still cranks and drives fine. The next day, about halfway through the day, it goes away and the gauge is reading the normal 14 volts.
Basically, it's always reading "not charging" when I first crank up in the morning. And it goes for a while. Drive to work, park. Drive to lunch, come back. Then when I'm going home in the afternoon, or later in the day, it goes away and the gauge reads 14 volts. Couple things...
1) Could it still be that the alternator needs replacing?
2) Could be a loose connection I suppose, haven't checked those, but it's weird because later in the day when it goes away, it's not intermittent, it basically stays good the rest of the day.
3) It could be a computer issue too? I've had weird, pain in the ass, computer problems for YEARS. So it could just be that?
Thanks.
