OK. I am happy to share my confusion and show ignorance: perhaps I am just missing the obvious or forgetting some basic electrical theory from school.
Most 12 volt conversions, such as those on the Cornwall Austin Seven Club site (12 volt conversion and Another Way) use resistors to limit the current flow and diodes to replace the cut-out. This I follow.
However, many articles state that the dynamo can produce up to 30 volts or so. What prevents the dynamo from doing this and putting excessive voltage through the system?

Jamie.
