Something has to manage the current flow - relays or silicon I would guess. My knowledge of exactly how that motor/generator/braking gizmo is implemented is pretty hazy. Just exactly how does pushing on the brake pedal cause the generator to send volts to the battery? Anyone have any details or actual photos/diagrams?

OT is maybe Over Temp, which I think would hurt the battery. I will try out the L mode. Even with the fancy GPS/radio/CD the battery state is not very informative. I guess they think the early adopters come from the idiot light school??? Just for sheer amusement I would like more precise info. That cheesy green display down by the speedo/tach is next to useless IMO.
