Posted: Mon Dec 18, 2006 9:44 pm Post subject: 12volt vs 24 volt system |
|
|
I have a 51 M38 that I just got and I want to go as original as possible yet still use it as it was intended. My question is there any advantage of going with 24 volt system vs a 12 volt? I am sure that there is a price difference on parts and availability. Also should I ever want to sell some where down the road is there a resale value difference? _________________ Michael G.

This issue is repeated at least evry three months or so.
Electrical systems were updated over the years for several reasons. To increase performance, lighten components and improve reliability. In the civvy's 6 volt was finally replaced by 12 volt during the late forties thru the mid 50's. Heavy civvy vehicles went to 24 volt. In 1948/50 The military skipped right to a 24 volt standard to match all the friendly nations military equipment and at the same time double the performance and reliability while halving the component weights and sizes from 12 volt to 24 volt. Today as we speak the industry is moving quickly towards 42 volt systems.
With that said why would you not want the improved performance and reliability of the 24 volt system in a vehicle that originally came with a 24 volt system? One reason in money. If the M38 already has been fully converted to 12 volt it will be expensive to convert back. If it was converted to a modern 12 volt alternator system then replacement parts aren't too awful expensive. Older 12 volt DC generators and starters are getting very pricey. Will it improve resale value to return the vehicle to it's original electrical system? You're darn right it will.
From a strictly performance/reliability viewpoint it is in my opinion hands down in favor of the 24 volt system. The system can be intimidating to the novice but there's plenty of help out there. In fact that's why we have this site and the M38 Yahoo Group. We have all the electrical troubleshooting, repair and overhaul data stored on these sites free to you to use. This 24 volt system has been in use with only small changes to the generating/regulating side by the free world's armed forces for 56 years.
So the choice is yours. _________________ Wes K

Well I guess that settles it 24 Volt it is. I have not had my jeep long enough to see what has been changed but I believe that it is 12 Volt. I got it for free so that helps on the over all cost. As mentioned in a different post subject this had some Civ mods done one was covering up the cowl battery box. I will have to cut along the bondo line and see what is underneath. I probally won't get started till Spring any way.
By the way does any one have some good pictures of the cowl battery box with the lid off / no battery and the inside of the tool box. I am sure that there are some in the gallery but there are also so many pictures that they might be hard to find. _________________ Michael G.

Well I guess I ned to set up a flicker acount to get the pic the problem is I HAD a cowl battery opening but the CIV mods filled it in so I was just wanting to get a visual of the openond/lip and depth. But I guess that the make the cowl battery boxes too for the M38. I did see the under the hood box that is available.
Is there any one on here in the St. Louis area? I have not had a chance to look at all the locations. _________________ Michael G.

You guys are funny. As long as the way thet attach is the same. I am lookinf for detail in where the box meet the cowl. I figure that it would have to de raised a bit so the seal would work. In the above pictures id the silver box the cowl box.
I am trying the picture one more time. (looks like it works in the preview)
