the voltage regulator is internal to the pcm,( powertrain control module) is the engine computer. you may try a junk yard for this but be sure you have exactly the same options on both vans or it may not work, also i know some of these computers are bieng remanufactured but i am unsure of the price

What? If it was it would fry the computer.

is in the altonator.

no it wouldnt fry the whole computer, only the regulator portion of it, and most of the older pcms 84-90 had the regulator internal to the pcm, all the amperage of the alternator does not go through the pcm, the pcm tells the alternator what rate to charge at and it goes directly back to the battery. although i am fairly certain of this i will recheck my facts, there was allways an exception to the rule...i have been a chrysler tech for 20 years
