I have a Volvo Penta D6 which includes a 150 amp VP alternator. This feeds a Argodiode 180-3AC. A recent voltage measurement showed 14.77V on the input side and 14.45V out to the 3 battery banks. Clearly the compensation is working.
My question is this. Who in the system is responsible for regulating the voltage? I presume the Argodiode is only monitoring the voltage drop. This implies the alternator has a voltage it is working to, perhaps 14.4V, but is designed so it can be 'influenced' to go a little higher by the compensation terminal. Do I have this correct? Is 14.4V a standard output?
Thanks.
