With modern batteries voltage regulation is desirable as not supposed to exceed 14.6/7.3 volts. Most extensivley use the Summer charge(or remove fuse so none) for day running and rely largely on a modern permanent intelligent bench charger. I cannot see why a suitably configured 6v electromechanical regulator cannot be used, with 3rd brush adj to not exceed about 8amps charge lights off. 12v electro mechanical regulators have been used but the types also with current reg probably will not adjust down to 8 amps so the 3rd brush is set to provide this maximum. On a 6v dyn with original field winding twice the normal field current is switched so short contact life is reported, and the field winding, maybe ditto.
