battery light on sometimes??

[sho1995HG]

I had my alt. and batt. tested and they pass the test done by AUTOZONE and my dad frieds tester. I don't know why my batt. light keeps coming on. For example in the mornings it does not go on but when I come home from work around 3pm That darn light comes on. As soon as it gets good air flow from driving in the freeway the light goes off but as soon as iget off the freeway the light come back on. Please some one help me

Maybe its your alternator not charging correctly, Thats a doosy man. I just sawpped my alt. it was very easy maybe you could swap a good one in and see if it stays with that Alt. and then move on to all your grounds. Thats just a shot in the dark, good luck.

Just found out that the light just comes up only when the themp. gage hits on the middle. Thats way saw the light come up after work only. SHOsFAST thanks for the help. I guess I have to go back Autozone to use that life time warr. Again.

dantheman68 so once you changed alternators the problem was gone?
