I am restoring a 1955 GMC TF and in my search for parts it seems the 6 cyls
were 6 volt and the v8s were 12volt at least in the model 100 trucks. A
couple of years ago at the Wendell spring swap meet a guy had a 55 TF that
had a six cyl with a 6 volt system. My wife wouldn't let me take it home.
And the GMC parts books confirm that this is the way they came from the
I hope this helps.
