If the cut out isn't closing (and everything else is correct) then charge isn't being switched to the battery, and the ammeter will not show a positive charge.
What happens to the ammeter reading if you close the cut out with the engine running at more than tickover?
I don't know where the field resistor is in the system with your kind of cut out - someone else will have to tell us. I have the cutout with the bigger base, and the resistor is underneath, in the base. You have to remove the cutout to get at it. But yours ... I don't know.
You don't need a field resistor to get things working, but without it, the "Summer" position is meaningless.
"Winter" means the two terminals from the dynamo are connected together and you should be getting full charge, which should go through ammeter to the battery if the points close and are clean enough to conduct electricity.
