That wire linking the dynamo terminals is the cause of there being no difference between summer and winter charge, it is effectively on winter. If that wire is replaced by a resistor of about 3 ohms and a high wattage it will give you summer charge as in the wiring diagram I posted. That box on the dynamo contains the resistor and field fuse as shown in this photo
