Start with checking the alternator voltage with a multimeter. With the car off check the voltage in the battery which should be holding 12v charged less if flat of course then start the car and test the battery again. If the alternator is good you should be getting a reading of 14 to 14.5 v if it's the alternator it'll A) not put any charge into the battery or B) be a very low voltage being anything under 13.5 v
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.
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.
