Convert CUCV to 12v pro vs. cons?

[medrod2006]

Hey guys I was wondering if I should keep my CUCV 24v or just convert it to a complete 12v. Its an 84 and I just got it so I am fairly new to the whole vehicle/system also if I do convert it how much work am I looking at?

Why would you convert it? In stock 24v format it works preaty well. Do you know how to comvert it?

If you do a 12v conversion, please use the Rosscommon Equipment Company method. It is well documented and works. You can also restore it back to 24v easily. We have discussed it many times.

If you do your own, then you will be on your own as far as troubleshooting any future issues.

Weekly I help someone with an electrical issue. With it being stock I can look at the wiring diagrams and 98% of the time tell them what to look at and fix.

A converted system, it is a shot in the dark.

Why?

About 98% of the truck is 12 Volt already. I do recommend removing the resistor from the firewall behind the air cleaner and supplying the glow plug relay with 12 Volts off the main 12V bus on the driver's side of the firewall. Other than that, I'd leave it alone.

Maybe you want to convert it to 12V to be easier, simpler, or common to other civilian vehicles? Maybe because the truck is new (to you), and you have not familiarized yourself with it yet?

Do not be concerned with the stock 12/24V electrical system. Most that are have never read the TMs, or remotely attempted to understand it. Is it different?, yes. Complicated?, absolutely not using the TMs, and this forum. I have come a long way since buying mine. Learning and understanding it has actually been enjoyable.

As stated before do the resister bypass to the Glow Plug relay, leave the rest alone.

IMHO don't convert. 24 volt starter is wayy better than 12 volts.

Do the DH mod and down load the tm's and read the wiki

At first the thought of having a 24v/12v hybrid system is overwhelming and hard to wrap your head around. I ended up getting rid of my first M1008 because I wasn't familiar with it and kinda got scared off. But this time around with my M1009 I have a better understanding of it.

Familiarize yourself with how the systems operate individually and how they interact with each other, and you will be fine. A 2000 Civic is more complex... Nothing about a CUCV is that complicated...it's a mid-80's Chevy.

I don't think it's worth it to convert it.

But do some of the popular mods/general maintenance stuff to it (doghead relay/12v glow plug bypass, replace GP's, and the glow plug relay, check the alternators and grounds) and it will be fine.

Ive owned & driven both 12V and 24V CUCV's and the 24V is wayyyy better. Even with the extra alternator and slightly more expensive starter.

Keep it 24v, it should help you when you go to sell it. I know there are a lot of guys (myself included) that would pay more money for a truck that has the original 24v system.

When I replaced the 6.2 with a gas engine I made sure I kept the remaining 24v system intact. I wanted the truck to still be able to perform it's military intended tasks. My starter is a 12v with the 24v solenoid. Works fine.
