Okay so my old Kubota alternator turned “backwards” when installed on my O-320. From what I can tell this is typical, and my (limited) grasp of ancient high school physics tells me that the rotation direction should make no difference in terms of generating electricity.
Does it make a difference in some other way? I figure it must or manufacturers wouldn’t bother to spec it. I’m told that on twins with engines that rotate in different directions, there are different alternators to make sure each rotates in the “right” direction. That would suggest there is a “right” direction. What am I missing?
