Question about 2001 Chevrolet Metro
Ususally - in the case of a vehicle dying at low RPMs - the alternator is to blame.
Your vehicle runs off alternator power. The battery is only there to start the vehicle.
Sometimes, however, a battery will develop a bad cell and cause the alternator to overheat or damage it in other ways.
Most auto-parts stores will LOAD TEST both items for free in order to get your business on replacement parts. Simply testing them with a voltmeter does not give an accurate diagnosis of what is wrong.
If you DO have a Digital Multi Meter - set it to DC-20 and measure the charge level.
the vehicle's battery shoud be between 8.5VDC and 12VDC while not running... and 14.4VDC +/- .5VDC while running.
Any major variance to those specs will tell you which component has failed... Also - you can try and duplicate your current problem - except this time, after starting the car - remove the positive battery post. If the car dies - the alternator is bad.
Have them both LOAD TESTED, and if you need further help - use the "Continue with this Expert" option so we are connected in the future.
