If a little is good, then a lot's better. NOT!
It seems that VW did such a good job of insulating the terminals on 1994-1995 Golf's and Jetta's (AL0185X, AL0186X, AL0181X, AL0184X) that they inadvertently created some low/dead battery problems on these cars. In some cases the eyelet connector of the wiring harness, which connects to the B+ stud of the alternator, had just enough extra insulation applied to it to keep it from making good contact. This in turn prevents the alternator from charging properly. To prevent a return trip to the battery charger, VW suggests that you disconnect the battery ground, remove the eyelet terminal from the alternator B+ stud and remove approximately 6mm of insulation from the terminal. Then, some die electric gel should be applied to the eyelet before re-attaching to the B+ stud with a torque of 13Nm or 10ft.-lbs. Next, re-attach the battery ground and get on to the next tricky subject.

Old Bug New Parts
Alternators which fit the 1975-'79 VW BEETLE and SUPER BEETLE (AL82N) are of Bosch Germany and Brazilian manufacturing origin, as well as Motorola USA. While these three styles of units are totally interchangeable on the car, the Voltage Regulators are not interchangeable between the three. Until this point in time only a replacement Voltage Regulator for the German production alternators has been available (p/n 0 192 052 007). Now Bosch is introducing Voltage Regulator p/n 9 190 087 003 which is a direct replacement for the Brazilian produced units. Retail price for this regulator is $23.60.
