I'm afraid that the reg/rec you have is not suitable for charging a battery from a standard lammy 12v stator. You'd need to transplant the vespa coils (7 wire stator), it was meant for, onto a lammy backplate.
You need a G,G,B+,C,E reg/rec.

If you mean the old AF DC type then no that is different again, similar to the 6v Motoplat system, although 12v.
To run DC from a single power wire stator you need a reg/rec from a cosa, late PX or LML machine. Wired correctly these will give a controlled half wave output befitting the battery's state of charge.

Green / red / white are ignition and go to the CDI. This leaves only the yellow to go to the reg/rec. You can use the A,A,G,B+,E reg for AC only using the A,A and earth connections but, as I said, that stator/reg combination will not supply DC to charge a battery.
