ooooooh question about a chevy....bought new alternator and still dies?

Mix a little baking soda and water and clean the battery. It will fizz. Then rinse off with clean water.

Check the water level in the battery, fill to the bottom of the slot inside. You will see when you remove the covers. Use distilled water and not tap water or spring water. Distilled water best.

Clean the Cable connectors and battery posts. They make a little tool for this and it less than $2.

See if it work. If not take the battery to Auto-Zone and have them check it for free. Be prepared to have someone take you.

You can call other parts store if you not have Auto-Zone.

It's likely ready for the recycling bin, for quite a number of reasons:

(1) The Chevrolet line overwhelming dominates Consumer Reports' 2008 list of Used Cars to Avoid.

(2) General Motors overwhelming dominates Consumer Reports' 2008 list of the Worst of the Worst.

(3) The 5-year Reliability Percentrank average for the Chevrolet line is .32, on a scale of 0.00 to 1.00. For reference, General Motors' overall average is .31, Honda's overall average is .84, and Toyota's overall average is .89.

(5) General Motors dominates AutoOnInfo.net's 2008 list of Automobiles with Worst Engine Reliability.

(6) General Motors dominates AutoOnInfo.net's 2008 list of Automobiles with Worst Transmission Reliability.

(7) AutoOnInfo.net's detailed reliability and durability studies suggest that a typical 3-year-old Chevrolet is as troublesome to own as a typical 26-year-old Honda and a typical 19-year-old Toyota.

Scope has good advice. Take it in to have it bench checked.

Clean and double check the battery levels if it has holes for it.

also, check your vehicle harness, follow the harness from the alternator up the wires, to the next junction, and make sure that the wires are not broken or corroded.

What has the alternator got to do with the car dying? If that's why you replaced the alt then by now you know that was a mistake, an expensive one at that. We need more info on what's happening.

fryed fusable link in harness to alternator or possible bad alternator have it bench tested or you could get it to garage and have them do a starting and charging test
