You can buy a Bosch rebuilt alternator from your auto supply store. Generally they cost around the $100 - $200 range.
The regulator is internal to the alternator! Just replace the alt. The alternator has an internal regulator that can be replaced by itself; however, when there is an issue with the alternator, it often involves diodes in alternator instead of or in addition to the regulator. better repair shops will often take an alternator to an automotive electrical repair shop for same-day rebuilds, with the value much higher than a cheap rebuild in a chain parts shop, and hundreds less than a dealer replacement. You want Bosch or your own Bosch rebuilt
If it's properly connected, it's just worn-out. When you get it replaced, make sure you get a new one and not a rebuilt alternator. I had a brand new Bosch alternator put in my 1995 Skylark about 4 years ago and it's worked like a charm ever since.
does it have a belt driven alternator ? you might be able to run it off the alternator like the jetta diesels do or any diesel for that matter but you may have to resize the alternator pulley to fine tune the readout. bosch alternators are used by vw but it gonna cost $$$. hope this helps
Absolutely. It will go right in. The only thing you want to be careful of is the alternator--if there's a Motorola alternator on the donor car, make sure to take the Motorola voltage regulator from under the back seat and the wiring that runs between them unless you want to swap the alternators, which isn't hard. If there's a Bosch on both cars, you're golden.
Try a Bosch alternator,,,,,,,really works Make sure the belt is not slipping. Also, troubleshoot before replacing parts in the dark - that is expensive and fruitless.
Here is how my [http://www.themotorbookstore.com/caravan.html 94 Dodge Caravan Manual] says to do it. 3.0l Engines The 3.0L engines were equipped with either the Nippondenso or Bosch alternators. 1. Disconnect the negative battery cable.2. Install a 1/2 in, breaker bar in the tensioner slot. Rotate counterclock- wise to release belt tension and remove poly-V belt.3. Remove the alternator mounting bolts (2)4. Remove the wiring and remove alternator.To Install:5. Position the alternator onto the engine, then install the wiring.6. Set the alternator against the mounting bracket and install the mounting bolts.7. Rotate the tensioner counterclockwise and install poly-V belt.8. Connect the negative battery cable. 3.3L and 3.8L EnginesThe 3.3L and 3.8L engines were equipped with the Nippondenso alternators. 1. Disconnect the negative battery cable.2. Remove the alternator drive belt, by relieving the tension on the dynamic tensioner3. Loosen the nut on the support bracket at the exhaust manifold, do not remove it.4. Remove the alternator tensioner/power steering bracket bolt.5. Remove the tensioner stud nut and remove the tensioner.6. Remove the alternator mounting bolts.7. Remove the power steering reservoir from the mounting bracket, do not disconnect the hoses, and position it out of the way.8. Remove the alternator support bracket bolts, Remove the intake plenum to alternator bracket bolt and remove the alternator support bracket from the engine.9. Remove the alternator from the engine and disconnect the electrical leads.To Install:10. Install the alternator in position on the engine and connect the electrical leads.11. Install the alternator support bracket, tighten the retaining bolts to 40 ft. lbs. (54 Nm). Install the power steering reservoir on the mounting bracket.13. Install the alternator mounting bolts, tighten the bolts to 40 ft. lbs. (54 Nm).14. Install the tensioner and tensioner mounting stud. Install the retaining nut on the exhaust manifold.15. Install the alternator belt, insert a 1/2 in. extension into the square hole in the tensioner and turn the tensioner. Tighten the tensioner bolt.16. Connect the negative battery cable.

With a Bosch rebuilt which is guaranteed, (shop around) and about $150-200 Samoans, labor is about two hours from a good mechanic, here in Maine we get it done about $280.00 total. VVVVVVVVVVVVVroooooooooooommmmmmmmmmmm!!!!!!!!!
Look under the back seat, on the other side of the car from the battery. That's where VW put it at the factory. If you have a Motorola alternator, it's a little silver box. If you have a Bosch, or a generator, it's a black box.
The Bell housing on the engines are located in slightly different areas. Thus the Altenator was relocated. The Super Beatle Altenator is 3 bolt, and smaller. HOpe this helps.. Reximus Manning. There are two alternators for Volkswagen Beetles: the Bosch AL82X, and the Motorola abomination they threw on there for a while when Bosch couldn't make enough AL82X to meet VW's needs. They're the same size, so if you've got a 74 SB and a 73 alternator, go ahead and install it Since the sheetmetal is the same between the two, you're fine. (If you were moving an alternator from a 72 to a 74, you'd have to switch the backing plates because VW changed the fan shroud that year, and the backing plates are different.)
