The light shouldn't be on if the 'D' connection isn't made with the ignition turned on. The light's circuit relies on a chassis earth (via the dynamo) to be fully made.
Is the modern resistor connected somewhere between the 'D' and 'F2' terminals? if so it's probably replacing the original open wire wound item.
Can you put up a diagram or maybe a photo of what the Diode is wired to so that someone on here can work out what it's supposed to be doing?
