I just had to replace my alternator and the battery light was coming on when I had slow engine speed (under 1000RPM)...It gave me little warning and completely failed after 20 miles, then the battery went dead and , of course, the engine stopped...

How do you know your alternator is bad?

If your battery is always going dead a day or two after a boost, then it most likely the alternator. Two surefire ways to see if the alternator is bad is to take the positive (red) battery cable off after starting the car. If the car still runs, alternator is good. If the car stops running, then it is likely the alternator. The battery is just to turn the car on and then the alternator regulates the initial charge coming from the battery and that powers the car. Another thing you can do is to run a voltage check at either the battery or on the alternator with a Volt Ohm Meter (VOM). If the voltage comes back as 13.5V or better, than the alternator is good. Less than 13.5V, and it is likely the alternator. Be advised, though that what could look like an alternator problem could also be your ignition switch or starter.
