  • This is a military diesel generator I bought from auction. It's 16 years old and has been sitting outside, un-used, most of it's life. Lets bring it back to life. Model: MEP-831A, which is a 3kW 120/240V model. It has a single cylinder Yanmar diesel engine. Model L70AE-DEGFR, or typically we just say L70.
    This is about a 6 horsepower engine, but probably feels more like a 7 horsepower. The data sticker says Cont. Output: 4.4kW, and Max output: 4.9kW. 296cc displacement.
    Generator Control Boards:
    Kurt Klopp designs and builds control boards for several military generators. In most cases, these are improved designs from the original. Visit his Ebay store here: ebay.us/yCVYqV
    "As an Ebay Partner, I may be compensated if you make a purchase"
    Note, I purchased my board from Kurt at full price.
    Buying a military generator: If you want to buy a military generator contact my buddy, Chris, here: mepgenerators@pm.me He is in North Carolina and buys generators at auction. Then he fixes them up, and load tests them before selling.
    Signature Solar Affiliate Links:
    If you want to charge an off grid battery bank using a generator, I recommend this charger from Signature Solar.
    Chargeverter, 100A: signaturesolar...
    Battery Bank, this is the one I'm using with my off grid solar system: signaturesolar...
    Inverter, I'm using the Schneider XW PRO inverter. It's low frequency, has a transformer inside, and handles my whole house and tools. signaturesolar...

    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.

    I've been looking at these myself and these look like great units. I would ditch the inverter, rectify into DC, send into charge controller and run the engine @1800 RPM. It should drastically increase the fuel economy and would still charge my batteries quickly.

    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! I supposed that if you were to contact him

      Usually the diodes will be for some kind of holding path check in the circuitry. When you press the start button some electrical test will go on and close a relay, allowing the system to come on. The diodes prevent it from coming on as soon as the on button is pressed. Don’t know this system though

    Whenever I replace old hoses I stop and consider whether the 50 year old perished hose will probably last longer than the brand new Chinese hose if I just taped the holes. Replacing old parts with new today is a greater risk than servicing the old parts. We can thank current anti industry 'service economy' megacorps for that.

      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.

    Mil Spec is sometimes very misleading. many years (several decades in fact), my Father worked at an Alternator factory in the UK, they made ones which you could pick up by hand, and other which you could sit inside the casing with plenty of room to stretch out. From a single KVA to MVA.
    Anyway, even back then, brushless alternators had become the thing. More reliable, less to fail, easier to services, more efficient. There really were not many reason to use brushed alternators any more.
    Except for one customer.
    The Military always demanded the "old style" brushed units as they were "tested in the field". The fact that they had to carry spares, they broke down more often than a brushless unit and the design was grossly outdated didn't matter. They always paid several times the cost - for an outdated, less efficient, less reliable, machine - instead of going brushless.
    They would not even allow for corrections to known design-issues, they wanted the OLD design, warts and all - 99 of them at a time, each one many times the price of a brushless alternator.
    "Tested in the field" was all they would ever say when challenged as to why they used dearer, inferior devices, "tested in the field".
    Mil spec is not always about quality - it is sometimes just "terrible but with a known level of awfulness" which someone signed off as being "correct".

    Your video brought back memories. I was a 52D from 76 to 90.
    From 87 to 90 I was an instructor for the 52D course at Fort Belvior
    10 years after I went through the course. I remember when these things
    arrived to be used for training. The gas 3 Kw before this went into service
    had a 4 cylinder engine on it. The pistons were tiny. Power generation field
    worked out really well for me. As a civilian I have been operating and
    maintaining a 7 Mg watt power plant for 32 years. Thanks for the memory.

      How does it compare to the 802? Well, the 802 is a 5kW, liquid cooled. This 831 is 3kw, air cooled. The 5kw has a huge surge rating, this 831 has some surge, but not as much. They both have pros and cons. I like both, but for different reasons. I think the 802 is a perfect house backup generator. I think the 831 is perfect for a cabin. The 831 could be pulled on a sled to your location, and if the battery dies, it has a pull cord.

    i work in defence and this is not mil spec. people get confused about what mil spec means. the true definition for mil spec is a device that uses mil spec parts. for electronics that means that they are rated to mroe than 90C and usually up to 120C, and they are quality controlled to be almost perfect. the entire electronics must be made of those parts- the kicker is that mil spec parts are 10-100x more expensive, and even 1000x more expensive than the commercial equivalent. mechanical mil parts are also subject to extreme quality control.
    what many companies do is claim to be compliant with a section of the mil-std-810G - which is the environmental test spec and just basically says 'test under these conditions and if its still running after the test then you pass'. But it doesnt mean it passed ALL the 810G tests and doesnt mean itll keep doing that thing for any longer than the test.
    so you end up with 'mil spec' devices that are just commercial crap inserted into dirty great big metal cases that resist weather and shock to pass one 810G test.
    most are just no better than commercial stuff but have a bunch of rubber mounts in them and many have the electronics just soaked/drowned in silicon so you cant repair them.

    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.

    I hate working on these things. They’re always broken. The only time there not broken is when there’re taking a break from being broken. It tricks you into thinking it’s fixed only to break as soon as you walk away from it. It’s a self aware machine that knows if it’s always broken then you won’t give it what it desires most in the world (new parts). It lulls you into a false sense of security thinking you have fixed the issue finally only for it do what it does best and BREAKS DOWN SO IT CAN CONSUME MORE PARTS. Then the cycle repeats.

    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.
