That's why I'm an ME and not an EE. Every time I see electricity there is something wrong (except for lights).
Do you remember the discussion a few years back when folks were arguing that a six volt starter would not last on 12v?
I have always believed that the horsepower required of the starter to spin the engine faster on 12v was not double, and the amps would actually be less than half the 6v requirement. My logic is that some of the energy goes into overcoming friction which is not proportional to speed, and some of it goes into compressing air, and you get some of that back even when the spark does not fire on the power stroke. So the starter does not really care about voltage (for a long life) but it is running a a lot less amps.
Which brings me to a question. Have you ever measured cranking amps on the same tractor with 6v and then with 12v to really see how the amps go down?

Today's Featured Article - On the Road with Dave Gohl: Tractor Club Beginnings - by Dave Gohl. I was surprised about a month ago when I got a call from a fellow tractor croonie. His message was interesting and to the point. He's says "Dave, I've been thinking about starting a Two Cylinder club for our area. What do ya think?" It was a loaded question. I said that I would be interested, and was wondering what his next step was. (Although I was talking under my breath, since I thought of this some years ago) My friend, Arlyn Lamb of Lakeville, Minnesota was sincere in his miss
