What year did jeep switch from 6 volt to 12 volt?
Someone please help I have been looking all over the Internet and I can't find out what year that jeep switched from 6 volt systems to 12 volt.

I have a Jeep service/ repair book, published by Clymer in 1971, for the Willys-Overland Model MB and Ford model GPW in military use. It states the electrical system is a 6 volt system. I used to own a '53 Willys CJ 3B that was 12 volts. I'm thinking the military models were 6 volt and the civilian models were 12 volt.

Edit: sells replacement 6V coils for Willys vehicles from 1941-1958.

6volt / 12 volt
The WWII MB/GPW models were 6 volt. The Miltiary models after that, from the 50's and newer, including the M38, M38A1, were 24 volt. The civilian models were 6 volt (CJ2A, CJ3A, CJ3b, early CJ5) and Jeep stopped using 6 volt in 1956 and switched to 12volt with the CJ5.

You will find many pre-56 models which have been changed to 12 volt which were originally 6 volt. The quality of the change-over varied. Sometimes thing that should be changed did not get changed, I.E. Spark coil, starter, instruments which might have step-down reisisters, or might not.

The time now is 07:31 PM.
