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...

Replace the Alternator before you get stranded as what happened to myself...

check the connectors and wires first. make sure their clean and tight. if beltis tight it should be ok. have alternator tested.
