Were 1955/56 Dodge trucks 6 volt or 12 volt?

Inquiring minds need to know!

 

Thanks,

1956 was the year Mopar went to 12 volts if I recall right, you have any numbers on the genny? I could try and look them up in my old Motor's manual.

Red tag 6v, green tag 12v.

What I'm trying to find out is if a Mopar heater switch for 1955/56 trucks part # 1568-393 is for a 12 volt heater motor or a 6 volt.  My 51 is now 12 volt and I installed a 12 volt motor in the heater so I'm concerned that the original switch won't work properly.

 

Last thing I want to do is burn up my new wiring harness!

Sorry, all I have is the year 55/56 and the part number 1568-393.

According to Bunn's book on the C-series, 12 volt systems were standard for the C-3, which started in September 1955...the '55 C-1s were introduced in April 1955.

Duh, I have most of Bunn's books and didn't even think about looking through them!  Oh well, thanks!

Yeah, my '56 is and always was 12v.

 

Since a 6v heater motor will draw twice the amps of a 12 of similar power, the switch should be more than adequate
