If alternator is charging properly you still may have A bad battery. Have battery load tested after fully charged. Also check for bad or loose grounds..

talked to a electrical guy and i did a test with all fuses with a test light on the neg. battery post with the test light on the wire (off of the battery obviously) and i started pulling fuses and the only one that dimmed the test light was the courtesy lamps/ cigar lighter. but i haven't had a fuse in that for months and it was out before i even had this problem, im thinking the diode in the alt. might be bad hins the reason im losing juice with the key on or off.. if anyone has any other ideas throw them out there at this point nothing is wrong.. haha

My 1986 Chevy Cavalier was doing the same thing, alternator tested good. Nobody could figure it out. Finally I got a new alternator and it has been running fine ever since
