How much EXTRA DC auxiliary power is available, on the F8 , over and above the "Base Load" of fuel pump, ignition, and LOW beam headlamp ? . I have no hard numbers, but I can confirm that my F800 will support TWO electric vests, grip heat, and HIGH beam for 24 hours straight, no problem.. . My question pertains to auxiliary lighting, an I wonder if I can run a pair of 55 watt H3 Piaa lamps, in addition to the 'normal' touring loads. . The owners manual spec of " 400 watts " alternator output means exactly nothing, as no net machine load is specified.
