When did GM change trucks and cars over to 12 volt.
I believe most manufacturers initiated the change from 6 to 12 volts in 1955-56
In the GM cars, the Cadillac, Oldsmobile and the large Buicks (Super and Roadmaster) went to 12 volts in 1953. Buick Special, the last of the straight eights, used 6 volts for 1953 and then went to 12 volts in 1954. Chevrolet and Pontiac last used 6 volts in 1954. I would guess pickups were the same as Chevrolet and began with 12 volt in 1955?
all chevs were 12 volt in 55
First series '55 Chevy/GMC trucks, the last of the AD series, were 6 volt. Second series '55 went to 12 volts.
What Randy P said
38fordpickup is correct plus the 1955 6 cylinder Corvettes all 7 of them!
Thanks guys good info. My friend says 1965 he is misinformed
Maybe your friend is thinking about generators to alternators...
Was Ford a day late and a dollar short?
1954 Models were 6 volt; 1955 Models were 12 volt.
Then and now.
Are you talking about ford or chev.?
