how tight is your serpentine belt? make sure its not to lose. also if you hook up a miltmeter to the battery on a dc 12 volt setting with the engine off it should read around 12v start your van and go look at the meter again it should read 14V if alternator is good

The easiest way to check the alternator is starting it then disconnect positive cable and if it dies, that is the answer
