In my lifetime in the US many vehicles were positive ground. Most companies started the switch to negative ground between the mid 50s and late 60s. Norton, Triumph, and BSA were all positive ground.Also, many were 6-volt until around 1966 (don't know for sure) but my 1966 Triumph was and my 1967 was 12-volt. I believe that all were 12-volt at least in the late 60s and in all of the 70s.So, in this community, negative ground is the oddball.
