Owen, good point that's why I reference my 47 which is a two brush system, but I did find this athttp://www.yesterdaystractors.com/articles/artint4.htm
The purpose of the 3rd brush is to control the generators output. This is done by grounding the 3rd brush and field coil. It is directly grounded when full charge is required and uses a resistor to ground for a lower charge.
But I would also like to hear from Jason's because I only know what I read and try myself.
