the first thing to do is remove the alternator belt and spin the
alternator by hand.
You may find the bearings are rough ..
you may find the shaft has-up down play.
you may find the bracket on the bottom of the alternator is loose or
trying to break.

then remove the alternator ( disconnenct battery of course )and take out
the brush package/voltage regulator ....
two screws.
you may find the brushes very worn down.
If nothing like the above issues arefound...
a new Bosch Voltage Regulator/brushes holder gizmo may get you running
just fine again.

I would not recommend buying a Vanagon rebuilt alernator from NAPA auto
parts.
I do just fine with Bosch Rebuilt Alternators, if I am buying a whole
new rebuilt one. That's all I'll buyeven.
I would take a change on a Voltage Regulator only from them though.

Despite others wanting cold drinks at a Starbucks, I decided we had better get as close to home and hopefully all the way home (about 45 miles).  Didn't make it; about 15 miles from home the fuel gauge quit as did the temp gauge.  I managed to get to a gas station.  Shut off motor to get gas and would not restart; we tried to push start but couldn't quite go fast enough; it almost started.  Towed home.
