Summary of change:
Subpage of MembersPage/MarcellGal/PowerAndTraction Strange, the audi alternator only has a THICK red (obviously positive) wire. The body must be the GND. I used to have some small-current (5..6 pin) connector on the alternator (on my cars earlier, at least where I checked). Maybe for the charger-control, or to disable charging at full throttle. I guess the charger-control is integrated inside the alternator in these audis. It will be easy to see if charging works, by looking at the battery voltage (standard procedure anyway). MembersPage/PaulF - Most smart alternators that I have dealt with fail safe to an output voltage of around 13.8V. Usually it is to allow the charging voltage to be lowered at idle to help pullaway. It is also used for feedback to the ECM as to the load on the alternator for torque adjustment.
