A quick way to check alternator on any vehicle is while engine is running,carefully touch a screwdriver to the spinning part (armature) of the alternator. If it is magnatized, it is charging. If not then alternator is not charging. The voltage regulator (the thingy that tell the alternator to charge) is built into the alternator. Replace the whole thing with a rebuilt unit.

Engine Dies, but Runs for a while After Jump StartingIf you're sure the alternator is working properly, I suspect that you have a loose, or disconnected, connection of the conductor [wire] that is supposed to carry the alternator charging current to the battery, OR a battery that has become defective.
