I know we talked in PMs and I told you what I thought was the problem but I see that you are still not getting enough voltage and it appears that you have done the right wiring. I have had a thought that the adapter that you have on the L wire may have a resistor that has too much resistance in it. This might prevent the regulator in the alternator from putting out enough amperage into the alternator fields for your loads.

Painless wiring recommends an 85 ohm- 5- watt resistor for the conversion to a 10/12 SI and most of the guys have used up to a 300- ohm 1 watt resistor for the CS alternators. I have seen some recommendations for resistors as high as 500 ohm but that seems a bit too high, it's a shot in the dark but i'd try a smaller resistor unless you already have a lower value installed. That 144 should be more than enough to handle your needs so I would take it back and get a replacement.
