      Theres a number of stators that I’ve been testing and as I looked at them… it suddenly hit me that I don’t know which windings to what.

      Most of these 70hp+ stators have a small area of let’s say two windings (or four windings) which are usually encased in plastic (maybe not)..

      And the rest of the stator let’s say 70% of the circle  of it has a whole bunch of other copper windings.

      There’s typically two yellow wires and some combination of red and blue and ground wires.

      Which wires actually go to which windings?

      The larger array of windings usually has very thick wire and lots of turns so I’m guessing that charges the 12vbattery.

      The smaller section you can hardly ever see the copper windings so I’m guessing they have to be protected because they’re so small they could corrode through?  Spark windings?

        The two (or three) large coils are called “charge coils” because they charge the capacitor in the ignition power pack.  Not to be confused with battery charging.   The other coils are “alternator” coils for charging the battery.  The two or three yellow wires lead to the rectifier for battery charging.  Two yellows for single phase alternator and three yellows for 3-phase systems.
