Thing is with the 3-brush...they are a lot weaker then the later generator...you start pushing them hard they overheat and burn armatures.
A generator is same as motor it has a set power they can handle (watts..hp..whatever)
If you double the voltage and keep the same output current the generator is now working twice as hard...some does that without complaining...the armature of the 3-brush isn´t in the bunch that happily runs all day long...it will have a tough time dealing with the increased power output..
I would suggest going another route then converting 3-brush to 12v...a lot of things can be done...some is just not a first choice to do.
