On a 6 pole, are two extra for lighting... I seem to remember..and your light switch kicks in the xtra windings ?
Totally depends on system design. They are normally designed as related to power requirements. A 6 pole system can be single, 2 wires, or three phase, 3 wires. Could be up to 3 single phase, 6 wires, or 2 three phase, 6 wires, I guess. Depends on how it is wired. Not sure about the extra lighting thing because most of these permanent magnet alternators only used a rectifier to convert AC to DC and the battery was sized to be the "buffer" instead of having a regulator. Many of the English bikes, BSA, Triumph, and Norton, used a Zener Diode on the end of the circuit for voltage regulation in both single and three phase systems as I recall. Many of the smaller Hondas used two separate stator coils, one for ignition and the other for lighting. Studying some of those wiring diagrams would probably shed more light on the matter.
The CR magneto was designed to run sans a battery. The leads are connected directly to the coils usually via a kill switch. My electrical prowess is somewhat shabby and I really don't know how it worked without a rectifier. It was basically wired as 2 single phase systems, 4 wires. I ran one many moons ago and it was somewhat critical to have the rotor and stator "aligned" to properly "charge" the coils for the desired spark timing (no keyway on the crank). Honda provided no instructions that I am aware of. The spark "advancer", or points cam, was fixed (no advance, no retard). It was designed to operate at 35 degrees BTDC if my memory serves correctly.
