Thanks for posting that Grant. It gives us quite a bit more to work with. There may be two capacitors in there, including a very small yellow one standing on its end in the upper right quadrant of the picture.
I think the next thing we need (other than a look at the alleged printed article in the vintage motorcycle magazine) is a circuit diagram for the full system. We know that three wires connect to the Magister unit, but we don't yet know where the ends of them go, and I at least haven't seen a picture of the magneto unit under the flywheel.
