Cool, so the field coil windings should be of a finer gauge wire than on the 6V system. (I have a pretty good multimeter)
However for the rotation question, is it only the brush plate that"s timed different for LH or RH rotation or is the rotor assembly obviously wired diferently?...Thanks for the info.

BTW The starter on the tractor is fine, I have gone through this and it is in a good way. I have good cables (tractor cable) ground strap, connections, etc. I"m not cutting corners here.
When one hits the starter with 12V, the sucker spins. With 6V, unless it"s just off a battery charger you can"t get one complete revolution of the engine. Fortunately, the tractor if cold will always start by being bumped. I suspect this has to do with the engine. I rebuilt the thing a few years back and to get the head/block mating surface squared up, we had to machine almost 0.200" off. This has affected the compression ratio and I assume that this increased (from 5.7:1) compression combined with a marginal electrical system is the root of the problem. Like I say, when jumped with 12V, the starter cranks over like a BMW.
