I have a 1944 Military Jeep and want to convert it from the original 6 volt system to a 12 volt system. I can find lots of info on the original wiring system, but need advice on wiring for 12 volts with alternator. It is very simple electrical system - some lights an ammeter and starter switch. What type of wiring do I use and where? What type of fuses do I need? I have 12Vbattery, alternator with built-in voltage regulator, and replacement light bulbs. But need help on wiring size, fuses. Etc. Do I need a ballast? And what is that for? Thanks for your help.

All Righty Then,

You gotta bunch of questions!

WILLYS or GPW?

Style Grill?

Making it a "Show-Off" driver.......Or Trying to really stay original?

If you know your Jeeps, you are probably "Picking Mine Apart"

I will stay with you all the way here, this is my hobby and I "Crusade" for the CJs

You are the 1st "Real Jeep" I have answered here!

You may have to "Copy and Paste" this onto a new tab.....Linking has ceased here, for the last week or so (this site has recently been up-graded, and they ain't done yet!)..Presently helping this feller, still going!....I can and will help you like this too!

http://www.2carpros.com/questions/1980-jeep-cj7-timingtuning-problem-with-a

His name is "WILLY", and I will "Introduce Him" (in all of his Completely Revamped CJ-2A, and "Transforming Glory" into a "Believable" MB---at least for the Ignorant, Happy Go Lucky Folks!

...........AFTER YOU RESPOND!!!!...........

All right, Imma member like you, I did not sign up to answer here, I just got hooked while laid-up with a broken foot(1-1/2 years) with complications.....This SITE is "ONE" of my hobbies!

Send Pics....I will help all I can (I do not know it all, but good at finding out!)

I pretty much started this, with basically a frame, engine and drive-train , 99.9% by myself--My other Jeep too ('77 CJ 5).......Owned 6 CJ 5s in past, Now just the '77 and the Willys.

Hi CJ Medevac-

Thank you for responding to my scream for help.

You have a really nice jeep. Well done. I am not going to pick yours apart I love it Congratulations on a nice looking jeep!

As for me. I could write a novel of the last 30 years. OMG. I just realized that I have had that jeep for 30 years! Bought it in January 1980 Sold my Ford Pinto for it. LOL Went to collage in it.

OK Here is the readers digest version:
This is a Military Ford 1944 GPW Composite Body based on the numbers was made in St Louis Ford Plant in April 1944

Frame off restoration in 1980-1981 Remember that in those days there was NO Internet Parts were extremely hard to come by, (had to ask friends if they knew somebody who might know somebody .) And reproduction parts were unheard of. The jeep had been painted a dozen colors but never sand blasted, so I had uncovered the original numbers before sandblasting. And those are the original numbers! - It also had Navy Numbers over the Army Numbers.

At that time- I purchased wiring from a Hardware Store and wired up the jeep. Everything is original Except converted to 12v with alternator. (Needed to be reliable to get to collage !)

That worked great until July 4th last year. ( For the last 10 years I drive Pearl Harbor Veterans in 4th of July parades) Last July I put a 6-volt siren on my 12 volt jeep. (DUMB ASS MISTAKE.) Everything shorted out fortunately AFTER the parade. Go figure?

I then spent 2 months with support from Remy Delco engineer to install a new alternator, battery, solenoid and replaced SOME wires That worked for 2 months with minimal driving maybe once a week.

Last Saturday. Dam thing smoked and wires disintegrated No fire, but wires melted and smoked. Not a pretty site.

At this point I am not inclined to purchase a new wiring system and rewire the entire jeep because:

1. I like keeping it 12 volts. It is more reliable.
2. I really don t have the time to rewire the jeep correctly, but may have to at this point ?
3. I don t have the money for $ 700 wire system.
4. Can you rewire a jeep without taking it apart?
5. I don t know if the new repo wires are compatible with 12 V.
6. I got the original wiring diagram- BUT that is for a 6-volt system! I am quite a novice of automobile wiring.

So I am contemplating what to do next

What is your experience with auto electrical systems?

Your Jeep is beautiful!

I wanted a MB or GPW, at the time of "Want", I found pieces of them, nothing in a "total package"

I settled for a CJ-2A with a good windshield frame, decent frame, "Shot" complete engine and complete "nice" drive-train.

The body was "Terminal"--So I saved and saved, till I could get a New one. Real winner. Fiberglass, NO MORE IRON OXIDE ISSUES! $950. It has major advantages, but some disadvantages.

I started my project in 1991, had it sorta Drivable and looking decent by '92 (still was burning 1 qt. Of oil for every 7 miles of travel). Over the years, I have made leaps and bounds with it, having ridded myself of the Evil Female I was Hitched to, and finding a "Quality One" who does me right!

The 2A has a stronger tranny than the "Baby Borg" in the WWII Models. But I do "Suffer" in looks. My windshield is Taller, and I will be modifying my Fuel Filler and installing my shovel and ax in the future.

Yes, I have a tailgate, but the swinging rack I made still gives me the "Rear Look" and lets me use the tailgate.

I have made many things "User Friendlier". But keeping "The Look".99% of all who see it, HAVE NO CLUE, and "Fictitious Stories" of this being a Fiberglass Mine Sweeper Model really throws Icing on the Cake!

As far as Wiring.I did all of mine from scratch! A Chicken Hatchery being remodeled, provided me with Mega Multicolored wire assets! (I was a Plumber, on that job)

I got the '43 MB Grill in '95, which is my best, Good Looking Improvement!

I used several Diagrams to Make mine like I needed it, I added Turn signals (using front black out markers) Added both tail lights, brake lights and signals and the Switch on the column. And you will see, I remodeled the dash, for ease in changing bulbs etc. Extra gauges and of course, My Riding Buddy, "Mr. AM/FM Cassette Radio" (Now trying to figure out this Computer Music Downloading so that I might Play "Portable" digital music thru the Radio of both of my Jeeps.

In our Veterans Parade there are usually 4-6 Jeeps (all Campaigns) Toting the VIPs around, I throw in my Tape with all of the WWII Era Music and we Cruise the 1/4--1/2 mile route down Main Street.

Much of my stuff is improvised, as I Started out with nothing, and still have most of it left!

I have Diagrams--Even some Military WWII (when I go look for them)

Send a List of what you need powered on your rig, All switches and gauges (Still using the floor starter. Mine's now a Ford Key operated Solenoid, as on my '77) you Sounds like you need to start from scratch with new wiring---On mine I went overkill for Normal Stuff 16 gauge on most. Bigger where needed!

It's not really hard doing it all, it's taking the time to LABEL it as you go, to stay straight.

I even implemented in a homemade fuse box---Nearly everything goes thru it.I used "Buss Bars" to hook my wires up to either "ON" and "Accessories" from the switch. Another for all of my grounds (remember, I'm fiberglass, I had to run a ground wire to everything)

I can make you a colored Diagram to make this EZer on you. If you can provide me a list of colors you can get, I will use them where I can.

If you will click on my Avatar/ Username and leave me your Email Address in "MESSAGES" I will send you a Sample of My "Revamping" in colors of a '79 Diagram

Over the years, I continue to improve stuff, like the "Solex Carb" so much better than the "WO", I will be labeling better than you see in my "Fuse Center", and one day, get back in there, and make the wiring look better, under the dash!

I drive Him a lot in the Summer.I'm so glad I "Broke Down" and began this project. Many around me thought I was Stupid, when I dragged him in.

My Daughter "Helped" restore him, when she was 2 and 3 years old. Was helpful many times!

My Daughter Started learning How to drive "WILLY" at age 8--Proficient at age 10 (Summers, when away from my Wicked X Female) Her Birthday, is my Hood Numbers

Continue to correspond here too!

I like doin' this stuff

Your Turn,

OK Big guy--I've been wondering how your Willys is doing.

It is such a nice looking rig, did you get thru your issues?

Reckon you thought I was crazy or something (actually, Doc, said I wasn't, I have documentation!), It is seldom that I get to commo with another Willys fan!

I really Love my "Willy", and I will be removing my hardtop soon and replacing my Right rear wheel cylinder, it's leaking down the tire a little bit.

Definitely time to get him back out for Summertime driving!

Thanks, at least for the previous response

Some pics of my man-cave, rather "Ranger Room" (Guest Quarters), My beautiful wife, of now, helped me create it, with my Ranger Gear, and other novelties I have inherited or collected over the years. My Rangerquin, is able to comfortably wear my uniforms, which seem to have shrunk, over the years. You can see my Jeep collections spread throughout.

Let me know if you would like better pics of my electrical stuff, alternator bracket or other.
