Basically you are correct, the 3rd brush wire becomes the field control to the voltage regulator.
But as well as voltage control, you need to limit the charging current or else you will get the armature too hot and the commutator will throw its solder.
There are solid state regs that will do this, and the old Lucas 2 and 3 bobbin regs too but you will have to set the max current down to a sensible figure.
