So... since it seems to be the alternator without a doubt, I wonder if there was anything that I have done to cause this problem - because if I am the culprit, then the new alternator will go up in smoke in no time...
What could bring an alternator down to its knees? an electrical overload? is it protected by a fuse or a "breaker"? Is there a home solution to see what the load is?
I know that there are codes in the high and low cluster that allow you to see the tachometer in digital output, gasoline quantity in liters, some other cute things along with voltage output directly on the computer readout in the cluster... There are many posts on how to access this information... I just do not recall, if any of those readouts provide the amperage of the load on the system... Knowing Germans, I would suspect that they probably have it built in somewhere, don't you think?
