This gives an idea of where the alternator is situated.....you can just see the stator (?) or armature (?) through the cutout. At the time of taking the photo MMC were a bit cagey about anyone seeing inside the housing as the cush drive component was being kept under wraps.
Thanks for that Jays it would probably be necessary to upgrade the rotor, stator and diode block.
As has been hinted at in PP's I would strongly suspect this has already been engineered on a Hog or derivative thereof.
Re-inventing the wheel is the term that comes to mind, someone that needs the additional current demands will reveal this with the aid of Google or other conduits out there.
If this proves fruitless, which I doubt somehow, then will be the time for an alternative solution to be looked into possibly utilising an additional belt drive from the propshaft.
A prop driven alterator the type used in small civil aircraft is another possibility, you don't need heating unless you have sufficient forward momentum being the logic applied.
Solar etc. etc.
