I finally did it. Changed my 47 cj2a over to 12 volt. Best thing I ever did. It finally starts right up. I struggled for years with the 6 volt. After long drives never felt confident I’d get back home. No problem now

Congrats! I did the same thing last year. My problem was all the 6v batteries were garbage and would last about 14 months -- just long enough that no warranty was left. Now it starts right up, and I can install 12v accessories.

Yes, I had the same problem. I thought I had an electrical draw that was running my batteries down but didn’t. Had to replace my battery every two years. I kind of miss the old sound of the 6v trying to start up though, kind of classic. But now my lights are brighter, and it fires right up. I feel more confident going places.

I really like my 2a but over the years have realized there is more than one way to cook a catfish. You'd think that over the 74 years since your 2a was built there might be a few things that could polish an already great machine. A one wire alternator is one of those things! Well done

Im going through similar pain with my MB 6v just doesn't leave many volts if you get a slight voltage drop somewhere or the 70+year old dynamo doesn't send out enough to the 70+ year old regulator. People always say its a grounding issue etc etc but my loom was all newly done ive connected addition grounds etc still had to get a push start last outing and cut my drive short, I think its 6v days are numbered.

Yes me too. Everyone told me as well it was a grounding issue. I checked them for years, changed wires etc, etc. but still had problems. So far no problems with the 12v setup. Miss the old sound of the 6v starting up, that was a classic sound but I think the 12v is the way to go
