No, you only need one resistor in the system, of about 3 ohms.
It doesn't matter whether this resistor is mounted within the cutout, on top of the dynamo or somewhere else. It always electrically connects between D (The output of the dynamo) and F (The input to the field coils). This supplies a low current via the resistor to the Field coils for Summer charge rate.
When you need Winter charge rate the resistor is shorted out by a switch so as to increase the field current and thereby increase the dynamo output current. This switch may be within the PLC2 Lighting/Charging switch, or may be a separate on/off switch if for some reason you are not using a PLC2.
Thank you, John.
That is really helpful, clear and simple. I some nichrome wire, so shall see whether I have enough for the resistor. If not, I shall buy one. I shall be using just a normal switch as I have none of the original electrics or switchgear.

Jamie
