I will take a look when I put the car on the lift to continue with some scheduled repairs and report back.
Unplugging the bcm won't clear codes, they cleared it with star

Good call. I ordered mine from some place similar to Rock auto... Don't remember anymore but I can probably dig up an online receipt somewhere if you need me to.

A friend of mine has mentioned shipping off an old alternator to be rebuilt by some aftermarket company that apparently makes really powerful/durable alternators to see if they can make a custom one for the merc. That'll probably be my next step.
