Which engine do you have? The regulator is a lot more work to remove from the alternator on the vehicle than removing the alternator. Can't remember how it is on a 4 liter - but it is certainly no easier than on the 3.0
The "internal" regulator is bolted to the alternator. It IS available separatgely for repair - and SOME replacement alternators come without the regulator. Standard practice around here is to supply the alternator complete with regulator installed and tested.

I have no idea what kind of '97 Aerostgar you have that would have an external or sepparate regulator - certainly not one built by Ford - perhaps a twin engined Piper?? ALL Ford aerostars of that vintage use a regulator that is attached to and part of the alternator. Yes, you can change it without dissassembling the alternator - and if it is a 3 liter you CAN change it without removing the alternator but it takes about half the time to remove the alternator than it does to finesse the regulator off and back on in place.. The chances of the regulator fixing it are significantly less than 50/50, in my experience.. Remove the alternator and replacxe it, complete with new regulator. Just do the job ONCE for a change.

good, no voltage drops. Battery holds a charge, checked under load and is fine.

check regulator & alternator separately to see which is bad? Alternator is a pain to remove.
