I guess I would still need to know if the 32 amp alternator is a 400 watt alternator. I'm a bit electrically illiterate, and I would think I would want to know how much power the bike, with the headlight on full is using, then subtract what the heated vest and t grips use. On my R100 GS with a 450 watt alternator, there is plenty to spare, so 400 isn't far off from that.
