That's why I'm not a gambler. I'm happy to be wrong :D

I think I have the same problem on my 18 but there are no F or D markings on the dynamo. Anyone know which terminal here is the field coil? Presumably that dot above the rh terminal means something!

Cheers Simon

On my G80S which is 6V positive earth with Lucas E3N dynamo the green wire goes to the field terminal which in on the left. The dynamo is marked with F & D. You should get continuity between earth and the field terminal either from an earth on the battery, bike earth or the large screw in the dynamo body that holds the field coil in place. Cheers. Bruce.

Thanks Bruce, I can get continuity between either terminal and earth!
