I hav a good lead on a nice cucv. Wondering how hard it would be to convert from 24 to 12 volt so I can run a stereo and other things. Anyone done this?

24 volt to 12 volt?

I would not convert the CUCV.. the 24 works fine... and putting a radio in is not a big deal... also the 24v starter is nice.... but that is my two cents
The only things that are 24 is the starter, and the glow plugs... everything else is 12v....

Hey DFG, if I decide to get the cucv can I pick ur brain. I don't know anything about the 6.2 but everybody I ask says it's junk. Also do u have any pics of yours?

I will help where I can... but I am no expert.. there are several on these forums....
I can tell you this.... I do luv my CUCV M1009... and it gets good milage...
Yes the 6.2 can be a bit of a pain, but like all engines.. you take care of it and change the filters as required... it will treat you well...
btw.. they are not designed for towing... the 6.2 NA is good.. dont tow unless you plan on modifications...
Another great forums for CUCV is steelsoldiers... they got alot of information specifically for military vehicles....

Thanks DFG
the people that say they are junk dont know what they were built for. They were built for reliability. Lets not forget this is 1980's technology and they are comparing it to newer motors.
the 6.2 is a great motor and do NOT convert to 12v It was not designed for that.

Ok, so I searched cucv on here for a build thread and can't find any. Is nobody building these up? Or r they perfect the way they are? If anyboby has any info I would appreciate it. Wana do axles and lift with wheels and tires. Are they worth putn the money into?

The starter is 24v the glow plugs are run through a resistor that drops the voltage to 12v because the glow plugs run off 12v. The second alternator uses a floating ground to bring the voltage up to charge the batteries. Both alternators are 12v.
Often on the starters the solenoid had gone out. New 24v are hard to find and spendy when you do, spendy compared to a 12v solenoid. Because they will bolt up many of the dead 24v solenoids have been swapped to a 12v version, works but won't last long.
The biggest trick is that you have to be smarter than the guy at the parts store when you need parts. You will need to know what it needs exactly so you can get the right stuff.
And we have a diesel forum here that has TONS of great info on the 6.2

I'm looking at the blazer model, the m1008
Blazer is the M1009.
The 12v conversion can and has been done successfully. If you want to do it there are several methods but only a few are recommended. Just don't half ass it and you should be good. The problem is the military specific parts on the charging/starting system are NOT common parts store parts. They CAN get them but you won't be able to just walk in and expect them to have them at any NAPA or Advanced Auto. When Big Ugly's 24v stuff goes south on me it's all hitting the **** can and I'm converting it to 12v for parts commonality.

AJMBLAZER.. that is blastphamy... dont be mean to BigUgly...
anywho.. if your M1009 is working good.. I wouldnt change out the 24v system.. but this is my opnion...
I have lifted my M1009 with a superlift 4" heavy duty springs front and back...
One thing I would recomend is an electric lift pump and a 'oil filter' style fuel filter modification...
That is what I am in the process of doing...

Well to let the cat out I am looking at buying a M1009 and I have the plans to convert it to 12v compliments of Roscommon Equipment Center and The National Association of State Foresters and Michigan Department of Natural Resources. They develop and test equipment for wild land fire control. http://www.roscommonequipmentcenter.com/news_notes/nn10.pdf
One I am stalking is in Lansing ends the 31 st.

DFG, what kind of mpg u getn with the 33in tires? Also the 1009 I'm looking at has been painted, but not nicely. Is the carc paint hard to paint over?
That stuff will kill you! Be sure to were a respirator if you sand it. A place had a CUCV near you for about $2,800 I'll see if I can find it brb *edit I had deleted it already it was green and being sold by a dealer (small lot) in CS.

The only time I actually checked.. (only had mine since July) it was 21.4 and that was a mix of city and highway... not too bad if you ask me....
I guess it will be better once I get all the bugs worked out..
anywho.. mine is not for show... I got the most beat up one I could find from GL......

Metro, I've already found one. Only 15k on it. But it was painted over the camo in black. And they missed some spots. Just want to cover the crappy paint job
CARC is great to paint over but hard to paint over if you want a smooth texture. Like metro said it's carcinogenic so don't sand on it without a respirator.
metro, watch out with those Michigan trucks. I heard from several people that the CUCV's were generally used hard, beaten often, and put away wet. Lots of rust and neglect. Mine didn't come from Michigan.
How? The 24v stuff in it works marginally better in some ways than the 12v stuff that the civilian trucks have and fall down completely in other areas. I will never own a Deuce and a Half and I have no reason to ever convert my civy vehicles to 24v so all the 24v stuff is to me is complicated jump start procedures and parts I CAN NOT get readily at a parts store in East Bum****, No Where.
I agree completely. Run it till something 24v specific dies and then ditch the 24v BS and convert it over to 12v for cheaper, easier to get parts.
No offense doc but I find it funny how folks will mess with the fuel system and a dozen other parts of a CUCV but abhorrently denounce even thinking about touching the charging system on a CUCV. Part of the reason I don't hit SS too much any more. Got sick of the "military spec is best" attitude.
That's the conversion I've heard recommended everywhere.
