As the proud owner of an MEP-803a I can say Kurt's products are top notch. Late last year I replaced the voltage regulator with one of his due to a failing adjustment potentiometer. From my own observations his regulator seems much more precise than the old original unit. (to be fair the original unit was 19 years old)

You brought back memories from the 1960s. My dad and I worked on military surplus gensets made by Onan. These units were for American Red Cross disaster service. The units were very well made and came with technical manuals etc. We had a non-military Onan too from the early 1950s that was hand crank start. It was a true beast to crank. We mounted it in a trailer as part of a lighting unit. This all was a great learning experience for a teenager. Thanks so much for your video and best wishes with your project.

When I was there, they had two 200kw turbine generators, I understand now they're using 150kw diesel sets.

When you opened the front panel at 8:47 - my eyes went straight to the little blue trimmers. Wow, PC mount trimmers exposed to the world. Those appear to be Bourns 3386 trimmers - very high quality trimmers that are 'kind of' sealed. We have found that they occasionally don't fare well when exposed to high humidity or moisture for extended periods of time. My guess - they went bad. Inexpensive at about $2 each. Bourns part number 3386P-1-xxxLF. The xxx is the resistance value which is printed on the part. For example "253" which would be a 25K ohm trimmer -- 3386P-1-253LF. The replacement board appears to have a digital-potentiometer on it (IC7) - good idea.

That's a pretty big 3KW generator set!! I would almost bet that the flaw with the engine speed module was with all them potentiometer adjustments just left outside of the module, in the open to salt air moisture, fumes, dust and potential of debris! And so it just might look as though the Marine Corps scrapped the notion of any future contracts and semi de-militarized them to a small degree. Those gen-sets were probably also to expensive to buy anymore and given the reliability aspects and well. That may explain the low hours on this one! The supply chain may have also failed to get these modules given just who is the manufacturer was that was subcontracted for that module build! Who the hell really knows for that matter! I know of a Chief Senior Military Technologist person that was contracted by Pentagon that may have been involved for the testing and approval for the purchase of such equipment for the military. His name is Lee Wheelbarger, Inventor and skilled professional when it comes to a lot of things related to the military!

Fun video. I'm a new subscriber. Yeah military equipment tends to be quirky in exact proportion to how different it is from any comparable commercial machine. The parts that are unique - like that speed controller and the whole idea of an inverter at the time - don't have the benefit of feedback from a mass market, so their reliability can be hit-or-miss even though they're made with very high end components and fab techniques. Commercial designs are often also flaky at the outset, but after a few ten-thousand units have shipped, problems that didn't manifest during design become apparent and get fixed. One other thing you inadvertently illustrated is why pulling tanks out of storage for deployment in Ukraine has been hard and painful on both sides. Multiply this generator's issues by about five thousand.

I was made a Sgt. of the guard and part my job was care of the generators at night. There were around a dozen or more, like each the size of four fridges or more. If it was more then some basic stuff, then I'ld have to wake some of the engineers. Lots of dials and switches to check and know how to start and run. I fully expected some Green Baray(sp) to try to sneak in and try to sabatage them, that being a choice target, but they never did, but the generators were the biggest prob for that month in the woods other than a couple of my guards.

One upside I see are that these readily deliver all the power promised (rated), while run-of-the-mill generators typically strain when running at their max rated power. Also, diesels like these can run and run (reliable). I got seriously interested in the 5 KW and 10 KW versions, until I realized parts could be challenging to get. It can be done, but that kind of project (chasing parts) loses my interest, especially when I have good alternatives.

Sorry, I was saying to myself "Who wants to watch 4 hours of replacing rubber hoses?" LOL. The return hoses on these are particularly thin rubber, and known to blow out. I used thicker fuel injection hose even on the return just to make sure. I also replaced the plastic "T" fitting with brass. The plastic one can crack over time. So, I'm not really doing a restoration, because I'm using a few things higher quality.

as a 91b i had to learn how to work on these because we never had alot of generator mechanics in my unit. these things sucked, they were old and reliable, yes. but they were always left outside and when something went wrong, combined with the issue of people in tents being pissed, they were never fun to work on. The biggest issue i ever seen with them was a shorted ground or a busted fuel tank, suprisingly i never worked on any of the disel engines in these.

Ahhh, when you opened the hood I was crushed! I was expecting to see a small, liquid cooled two or three cylinder diesel engine, such as a Kubota, that would run at 1800 rpm and allow for easily capturing waste heat as well. That's gonna be a screamer (3600 rpm). I suppose you could determine what the generator output voltage is and use a transformer and rectifier to go straight to the 48 volt battery. Could select a transformer ratio that allows it to run at lower speed, but of course at lower output as well. Still need to recover the heat in an off grid situation since that where most of your fuel goes, and air cooled just isn't conducive to that.

@@DavidPozEnergy Ah yes, I thought it was an 802 you mentioned. I'm not really familiar with the military sets, but 802 does sound familiar. Lots of information on these on Smokstak and Steel Soldiers, but sounds like you're well covered with your friend. ;) I haven't seen your videos in a while, but it used to be you had utility electricity but were more or less not using it. Have you truly "cut the cord" now? I would SO love to do that. ;) I'll admit, this set sure does look like a sweet little unit. I wonder what it's operating speed range is, no load to full load?

Im a 91D; I was surprised you like these. In my experience they were among the most unreliable other than the 805B, love the AMMPS series and the rest of the TQG lineup. PPUs are pretty cool too.

Part of the reason I liked them is because I could get them running even when it was 0°F outside. The others had a harder time starting in those temps. However, I admit there is a steeper learning curve with these 831s, they are not perfect.

For the fuel efficiency test would it work if you just filled the normal diesel tank to the brim. Run the generator for an hour with a known load. Then precisely measure how much diesel is required to refill the tank to the brim again. Then a simple calculation will give the efficiency now that you know the duration, load and the amount of fuel used.

You could make A offset tank just for the fuel return line purposes so you can run it dry. Through that separate offset tank connected into your fuel lines into A doubled up T- line brass fittings.,or metal ones the size of your other fuel input off the machine itself with A fuel filter,& water separator add on brackets tied together on one bar strip plate attached to the generator painted olive green to match it all.

That is an over-ride function. Perhaps you don't have oil in the generator, but you NEED to run it anyways. Turn that on, and the generator will run until it kills itself.

While it does primarily run off of diesel as it's fuel. Being that it is a military service generator it should be multi-fuel capable. If it is then that works in your favor as you can produce your own fuel for it. The smallest gen set my unit had was 5kw and the largest was 150kw, we were an Engineer company so we needed the variety at different times.

Well I've got quite a lot to say about single cylinder generators for off grid. I'm not in love with Yanmar single cylinder Diesels. Upsides are they are cheap[ish] to replace, downsides are any hours you get over 3000 are a bonus. I've had bad luck with 3 of these engines in my 7kva generator. At no stage was any load ever placed on this generator in excess of 4.5kw. So I've had 1x broken crankshaft at
