I'm not too familiar with electrical theory or how the EFI computer works, so excuse me while I babble with this idea. I have a 95 zr 580 efi, and there is not a day that goes by where I worry about having to rely on that stupid battery to get me through the trails. I've never had it die on me, but i've seen what cold weather can do to batterys. So, why can't the battery be removed and have the positive wire that once went to the battery, tapped into a 12V wire coming off of the stator, and ground the negative wire that went to the battery? There is 12V coming off of the stator, right? Is current draw an issue? Someone please tell me why this wouldn't work. And yes I know all the right ways to maintain my battery to prevent breakdown, but damn a guy could shave off another 10-15 lbs and not have to rely on that battery if this would work. If it is this easy I don't see why arctic cat wouldn't have done it this way to begin with.
