Looking for ideas. Over the past year, I've watched the my car slowly sink to the 12.3 volts its at now. Car is sitting until I get it back over 13.

So far I've:
-checked and trickled charged the battery, still producing over 1000 ccas (but don't know if that has to do with voltage).
-replaced the alternator
-replaced the exciter wire
-replaced the battery terminal bolt thing on the positive side (looked corroded)
-cleaned the battery terminal wire thing on the positive side (looked corroded)

Car is still at 12.3. Revving the car makes no difference in voltage. Scangauge is also reading 12.3. I don't have the big 3 done, as the terminal of the wire from the alternator to the battery that I had jumping along with the stock wire broke while I was removing the battery to get it checked out. I don't think that is making a drastic effect really as the problem existed even while the wire was in place.

Thoughts?
