6 Volt or 12 Volt?
 

For the most part all Dodge Power-Wagons from 1946-1955 were 6 Volt, and all Power-Wagons from 1956-1968 were 12 Volt.

The exact time that Dodge changed from 6 Volt to 12 Volt is not clear, and many 6 Volt trucks have been changed over to 12 Volt, so questions of how to tell what a truck was from the factory comes up from time to time.

Here are a few clues to tell if a truck was 6 Volt or 12 Volt from the factory.

The 6 Volt trucks have red tags that say 6 Volt on the Generator and Starter motor, 12 Volt trucks have green tags that say 12 Volt. Below are a couple pictures of the Generator and Starter motor 6 Volt tags on a 1955 C-3 PW.

Here is a 12 Volt tag from a Generator, all the 12 Volt tags are in the same locations as the 6 Volt tags.

Starting in 1951 Dodge changed to the gauge cluster in the middle of the dash, and the AMPS gauge had different markings for a 6 Volt truck Vs a 12 Volt truck.
From 1951 up until 1955 or 1956 when 12 Volt was introduced Dodge used an AMPS gauge that read 50 - 0 + 50 on the 6 Volt trucks.

Starting with the 1955 or 1956 Power-Wagon Dodge went to an AMPS gauge that read 30 - 0 + 30 for all the 12 Volt trucks, this gauge was used until at least 1960.

Starting in the 60s, maybe in 1961 with the Alternator replacing the Generator, the AMPS gauge read 60 - 0 + 60

There are other details that changed when Dodge went from 6 Volt to 12 Volt, like the dash knobs changing, so if more info is needed then what is listed above, feel free to ask for more detail.

 

I hope to update this page from time to time as more info becomes available, and feedback is given about other information that would be good to include on this page.
