Looks like your hose clamp is keeping the injection pump hold down front fully seating the injection pump while also breaking the seal on the hose clamp and the nipple to the injection pump. Then, diesel is getting into the crank case. Had this happen to me, minus the getting into the crank case...

I pulled the control panel and alternator cover off to have a look inside. It all looks neat and in order but someone was in there. Some of the caps to the brushes seemed loose to I tightened and tested again... less than 1 volt now with the breaker not tripping. It must be toast. I guess it...

I did not equate "work" with military ordering. Should have read more carefully!

The solution in my video will be way more simple. The ohm of the MEP 802A and MEP 803A are different than the MEP 831A, unless you also change the gauge.

The TM has you do it first exactly as I have it pictured. If it is not within range, then remove everything to confirm... but, it seems that if you remove it that you will more than likely get the same reading, and it is just removed so it's ready to be replaced. Unless you find something like a...

Well, this may end up being a short fix-up thread. Went through the alternator testing procedure as per the TM via P1, E & F. Resistance should be 13-16 ohm. I got 37.6... way off. I know temperature can effect this and it drift a bit, but not that much. Also tested the stator via P1, started...

White smoke after a cold start, even in a warm climate, is pretty normal in a mechanical diesel engine. Especially if it is a little rich. My diesel ATV with the fuel turned up has a lot of while smoke for about 5 minuets.

I have actually seen his videos and watch them in the past for other things. Unfortunately, I don't think his will be helpful on these units because they're unique to the MEP 531A. I think I have a bad alternator or voltage regulator at this point. Funny, I saw where you are from... I grew up...

I put a new diode in just in case, I had a bunch. Send me a PM with your address.

If I don't get this unit to make power, I'll just part it out and use the motor on something else. That was my backup plan. Hopefully you get yours going!

I just got myself one of these and am a bit stuck as well. Tried flashing, and I am only getting a little bit of voltage now. Breaker isn't tripping as soon as I start though. https://www.steelsoldiers.com/threads/mep-531a-fix-up-thread.208911/

Howdy all, Been a while since I started one of these! Got myself a MEP 531A at auction. Definitely had a bunch of hands in it, but, I got one of the best deals that was had in a while on one. I knew right away the breaker was pushed into the panel and the cover over the gauges was...

That was my thread you referenced above. I have since sold that MEP-016B, but it was running like a new machine when it went. Just take your time cleaning everything and putting to back together. There are some videos out there on these pumps that show them getting put together. Yes, they are...

You can adjust the stop to be sure it does not pull the fuel rack back to far, no? Here is what I would do with the sounds of what you're saying with the slight issue of the injection pumps and one having a delay in start. Remove the fuel line that goes from the fuel/water separator. Remove the...

Almost done with the turret setup as well. Waiting on one more part for the 1919A4 and I need to make one more modification the the cradle.

Made a little CTIS time laps for the YouTube channel.

Once I finish it all up! Right now, I have the winch & PTO fully installed and working. Have to do the rollers and fairleads. Waiting on the frame part to come that I did not realize I was missing.

Tested things out the weekend and put ~150 miles or so on the truck.

We'll get together one day and you can shoot it. I plan to get the Crankfire Systems for it too.

It's just a M1919A4 semi-auto. I'm not that cool!
