Alternator Voltage

I've installed a 100A bosch alternator from a 740 into my 244 but I've been having a few problems that I can't figure out.

The charge light glows faintly when I have high beam on with aux driving lights(the reason why I upgraded, I started more night driving). I've had the alternator checked and it didn't show any problems upto 50A (don't know why they didn't go higher). I've installed a new 110A cable from the alternator to the battery terminal. I've also tried 4 different regulators including a new one. I cleaned the terminals and the voltage raised a little but nothing significant. I've now changed the batt to a new 490CCA batt.

The weirdest thing though is that the opperating voltage starts at 13.5V and slowly drops to 12V but when I turn the engine off the voltage goes up, not down.

Weird, huh?

Any ideas what could be causing this?
I've got a good external regulator from my 144, would that be worth adapting?

Thanks!
