My stock observation for those venturing into Seven electrics...there are few circuit diagrams which show internal connections so very simple systems are rendered unnecessarily obscure, esp where parts are mixed. The Cornwall club article A Charging Refresher covers the 5 basic charging circuits with details of the cutout internals. And particularly for later cars Dorset Club John Cornforths diagram will also likely prove helpful.
A search of the old site will reveal vast info about regulators mechanical and electronic, often mixed with and complicated by 12v conversion. For unmodified dynamos a mechanical 6v regulator used with a the 3rd brush appears promising but it has been claimed that the switching action taxes the brush and rattles the timing gears.
For typical running today charging in the car can be kept modest and a regulated bench charger relied on for maintenance.
