Quite Charles!!
Thanks for your input Robert but the regulator is not, really, relevant to my question. I know that there are two alternatives for wiring a dynamo internally and I'm trying to find out what those two alternatives are.
I have made some progress in relation to that. On Dave Armstrong's excellent Spedex site there's a basic diagram that I suspect answers my question - see http://myweb.tiscali.co.uk/speedex/index...ge1173.htm. This indicates that one system has the dynamo field connected to earth (I believe this is the Lucas/English system). The second has the dynamo field connected to D on the dynamo (I believe this is the Continental system given that a Lucas A7 dynamo so wired would have two wires rather than on coming out of the dynamo to the D terminal). My dynamo certainly has the additional wire running to D so I think I've found what I'm after but confirmation that I have would be very gratefully received.
