I have a 1994 Tempo 4 cyl 278000 miles
Just a few days ago my alternator light came on in the dash at low rpm I had the alternator benched checked and they said it was ok , Then I replaced the battiey and cleaned all the cables . After 1 day the light came back on at low rpm (750 and below) This is even when I have eveything turned off ( radio, air, blower ete ) The belt is ok
my question is what could it be??????
thank you for any help
