Help me settle a disagreement between 2 authors of articles/books on Triumphs as to the year they (the Bonneville that is) first were equipped with 12 volt electrics. A book by Cane says 1966 while a long article on the Internet by Ian Chadwick lists that change as one of the innovations in 1964. The dispute has arisen in the www.classicbike.net forum because it was the first answer to a quiz created on that site for our members.
Who among you has unrestored Triumphs of that vintage to resolve the dispute?
