TD5 alternator charge

[Rossco84]

I've seen this discussed in many different forums but no definitive answer has been given that I can find. I want to know if I can get my TD5 alternator to charge at a consistent 14.4v as it seems to start out OK charging round the 14.5v mark but then seems to drop off to any where between 13.2 and 13.9v. I've got a dual battery setup in the car with a third battery in the caravan via Anderson plug. It almost seems like the alternator is temperature sensitive or something? Please help. :(

I'll let the experts respond better, but my understanding is that once you get to about 80?% charge the voltage drops to ensure no overcharging.
A fully charged 12V battery should be reading about 13.8?V
Now wait for the real answer/s.

I'd be keen to find the answer to this question too, as I can't make any sense if the voltages that I'm reading on my (standard D2a) TD5.
It might be a long while before we get an answer if this thread stays in the SII and SIIA section though. Can a Mod help out?
