I have a 96 olds 88 ls...I have replaced the battery, alternated and cables. Batt discharge light comes on after 5 minutes

What is your question?

After the car is driven about 4 miles...the abs light and low oil light are more intermittent than the battery discharge light is..there is no dimming of headlights or anything when the battery light comes on..bad cluster?? Faulty ecm??? I've had the alt and battery checked. .all at perfect numbers
