Electrical charging system

On the General Board I posted that one of many things that I like about the Nomad's design is the charging system seems to be dual or tandem , giving 600 watts from two separate 300 watt systems. I base this on what I can ascertain from the parts diagrams and the wiring diagram. This gives a high output without the use of brushes that were troublesome on my 1500 Goldwing. Is this the way you understand this system? In some cases if one side of the system failed such as one of the voltage regulators or stators would the other side of the system still deliver 300 watts? I would like to understand more about this system.
Thanks
