I am a new member of the Club rebuilding a 1949 Black Shadow. Having taken advice fom the Club as to sources I have ordered an electric starter kit from Francois Grosset. He is asking whether I require +ve or -ve earth. I am prompted to seek opinions and advice on this and also on the matter of generator or alternator (ie with the appearance of a generator) My objective is originality in appearance together with sensible improvements which have been tried and tested.
