Resolved!

I replaced the regulator with an older one I had on the shelf here...Brushes are at 60% but I will be ordering a new one shortly.

Once I re-installed everything I found that I still had 30V at the alternator wire on the electrical distribution block.

I probed around a bit and found that the alternator terminal was not making very good connection. I fixed that and saw the normal expected voltage at the battery.

I also found that I have ~ 0.5 V drop between the alternator line at the dist block and the battery.

With everything fully on/loaded I measured 12.8V across the battery but 13.4V at the alternator line.

I'll have to re-do my distribution setup so that the alternator is directly connected to the battery, like I have in my 190E and 300D.
