6 volt or 12 volt 1954 f100

ok i've been all over google and i've found that '56 was the first year of 12v for the f100 (i also have a '56 shop manual). i took apart a spare cluster i have (53-55) and all the gauges are embossed with 12v on the cardboard on the back?. did they have some 12v in '55 or something.

 

could have been a late production 55, or someone converted it later

 

all my 55 or older were all 6's

 

i should have said 12v printed on the back. on the front of the gauge it says "K-S", then a part number and on the back the cardboard is embossed with "K-S" so i think it's original paper back. i'll check the one's in the truck now, the truck is 12v (now) and i want to get the original gauges working. i bought some 12v converted one's but the faces are plastic (they look like the originals though).

 

Some of the big trucks & custom cabs 53-55 were factory 12V. We have a 55 F-750 that was 12V from original.

 

1 oldtimer ?did they have some 12v in '55 or something.
I just looked in 48-55 Big Job parts catalog and it says Ford used 12 volt in big trucks from 52 onwards. I checked starter,coil and generator.

 

Also, any cowl and chassis trucks that Ford buil in 56 such as for a school bus or other body type used the 53 to 55 style guage cluster with 12 voly gauges.

 

IIRC, it's really a matter of the resistor block that feeds the gauges. But don't quote me on that....mine's 6v.

 

hmm, so they used the f100 gauges in the cab/chassis trucks. sounds like they might be a little harder to find nos then using the aftermarket ones. maybe i'll see if i can test these.

Thanks.
