I’ve performed a 6v to 12v conversion on the major components of my 1955 first series truck. For the purposes of seeing if I can get the original 235 engine to crank I was going to attempt starting it without a 12v to 6v reducer on the ammeter. I’m thinking that I shouldn’t damage the existing ammeter and the existing ammeter (if it even works) should only show 1/2 as much charge (amperage is now cut in half) with the new 12 volt system, right?
