But at any rate, I was COMPLETELY on the wrong path with the alternator. I had it tested and the alternator is fine, I was kind of disappointed to hear that it makes 80 A and 14.2 V.

It seems, that the pulley, and the belt engineering is somewhat sub standard, as having the alternator driven by too big of a pulley. I noticed that the pulley on my alternator was a 2 piece pulley, and I thought about it, and I took the pulley off, put a washer in between and in distancing the two plates, it makes the pulley smaller. I gained 2.5 volts at idle, however with headlamps, fog, radio, heater, and wipers it still drops to 11.9, but does increase, albeit slowly to 12. I still think I should have maybe a minimum 13 V with all loads..
