I HAVE INDEED used a 6 volt genny coupled to a 12 volt Voltage Regulator and it worked okay to charge a 12 volt battery buttttttttttt before anyone has a calf now Im NOT saying its engineering correct, I'm ONLY saying it worked. A DC generator is more of a current device then a voltage device...

The engineering reason why is basically a genny dont necessarily know its output, such is increased EITHER by turning it faster orrrrrrr pumping more current through its field windings (the job of the Voltage Regulator control) which increases the magnetic field strength in which the armature is rotating thereby increasing its output.

BUTTTTTTT the problem is, the field windings have a certain max current rating and if thats ecceeded for too long a period they may overheat BUT MINE NEVER DID

Sooooooo it can work, my conversions all did no problem buttttttttt things have to be close to right which depends on the gennys field ratings anf if its a 2 or 3 brush etc and the VR performance and specs and the duty cycle and max current it tries to put in the fields etc etc etc so just cuz one particular genny with one VR works dont mean they all will BUT IT CAN WORK AND MINE DID

Hope this helps

Today's Featured Article - An Old-Time Tractor Demonstration - by Kim Pratt. Sam was born in rural Kansas in 1926. His dad was a hard-working farmer and the children worked hard everyday to help ends meet. In the rural area he grew up in, the highlight of the week was Saturday when many people took a break from their work to go to town. It was on one such Saturday in the early 1940's when Sam was 16 years old that he ended up in Dennison, Kansas to watch a demonstration of a new tractor being put on by a local dealer. It was an Allis-Chalmers tractor dealership, ... [Read Article]
