Battery and alternator test good .car starts ,drive then battery dies and wont start.

Maybe you burnt up the starter ! Do you know how to do electrical trouble shooting ( testing ) ,Voltage drop testing ? Are you familiar with a starting circuit on automobiles ? You can watch videos on youtube on such thing's . Is the battery good an have good connections .

Auto Zone does not test the alternator under full load so the test result could be borderline.
start the car and turn everything on. If the voltage drops lower than 14.2
replace the alternator.
also the battery could be being drained overnight. to check use a test light by removing a battery terminal and connecting light between battery and cable with car off.
if it lights start be removing fuses.
when the light goes off the problem is with this circuit.
lastly if the light stays on take the wires off the alternator.
if the light goes out replace alternator.

Sounds like alternator,if you can drive to Autozone,they will test both for free,takes just a minute,or remove and take up there,are your belts good and tight.Fusible link not burnt up.

If alternator and battery is good, check the ground cables from the battery to the motor and frame grounds.

It's either your battery or alternator have them tested. If your alternator is bad it wont charge the battery. If the battery is bad it won't hold the charge from the alternator. Good luck!

It sounds like your alternator went bad. The alternator is responsible for keeping your battery charged and at full power. If it goes bad, your battery eventually drains and things start to shut down.
Get your alternator and battery tested, I'm sure you'll find the alternator has died.

With the battery light on, it is leading me to think alternator not charging the battery. If you can get it started and running, take it to Autozone and have them test your battery and alternator (free test, they bring the machine into the parking lot to your vehicle). Hope this helps.

start your car and remove the positive battery cable off. if the car dies it is your alternator. alternator can test good but be bad especially on a cavalier. that is the problem i had and the alternator fixed it.

SOUND LIKE IT MIGHT BE DODGY ALTERNATOR YOU CAN BUY A ALTERNATOR TESTER FROM HALFORD. AND CHECK ALL CONNETION FOR WERE PARTICALLY THE BATTERY CONNECTION
