I converted a FV432 to the US type alternator (2920-00-909-2483) and, in error, used a wire that was not full voltage but rather went through a resistor. The alternator would overcharge, and could not be set (there is a small potentiometer on most of them to set the max voltage) so as not to. So the alternator is sensitive to the field wire's voltage. You would have to try it on the ferret to find out if it causes overcharging.
In Canadian service, there was a CFTO to install that alternator on just about everything (3/4 ton, deuce, 5 ton) with the earlier 25 amp systems as well as the ferret with it's British system. I always found them to be a reliable alternator and an easy conversion.
