Sounds like the Diode or the Voltage Regulator is going out on the alternator. I would recomend replacing soon. When one of those 2 componets go out, it really over heats the alternator. This causes the bearings on the back side of the alternator to fail, and sieze. This has cause some fires in GM cars and trucks.
The voltage regulator on a 1989 Chevy Camaro is inside of the alternator. If you are having issues, such as flickering lights, you might have to replace the entire alternator.
