Ran it for about 10 mins to day and place around 1500 watt load on it. I noticed that I may have incorrectly read Hz the other day at no load it runs at 64.5 ish. I did confirm the reading with my Fluke meter. The TM gives instruction on how to adjust this. 8. To adjust diesel engine speed...

I re-torqued the head today and checked the valve clearances, valves were spot on. Also checked where oil level was too 1/4" below full line on dip stick. Going to run it for awhile tomorrow. Is this generator safe for computer, microwaves, etc being a brushed motor?

More pictures. So far I cannot find anything broken or not working as intended. I only checked the Before on PMCS was a little early to fire it up also want to, check the Head Nut torque and valve clearances. since I have no idea if the military do this or not. Both are due at 20hrs, as well...

Received the generator today. Date of MFD is 12-14, very clean unit. Even came with oil and diesel and what looks like new near new wet type air filter. Starts really easy and produces power on meter. Hz meter hang around 63 kinda high but once its under a good load I'm sure that will go down to...

Added another military generator to my collection, A MEP-531a. I have been reading around on this site about them and seem to only dug up that these are sensitive to too much oil in crank case. It wont be here till the 4th of April. Does anyone have any experience with these? I have only seen...

Your rocker cover looks like this? Don't use that port to fill the engine, you might end up blowing smoke till the cows come home. Fill your set on this port.

"I noticed that when the rpms went down - the voltage output gauge would go dead as would the other gauges on the dash. Then it would speed up - and the gauges would be back to working again." The reasoning behind me recommending that you disconnect the battery was to prevent any issues the...

Might be the battery, try disconnecting it. See what it does after that. Also can you start a separate thread for your generators, it will help us better assist you.

Thank You

I am familiar with the Quad fuse mod, but what is a MOV?

Hopeful those part that you were linked have the working board you need. I really recommend that you try to figure out what cause that board to die. Check every thing you can, might be more than just the board that is broken. Ill ask a colleague of mine at my work that works at the same company...

I sent you a PM bimota.

MEP-831A Schematics, If I missed anything please let me know.

I will extract .pdf schematics here, I do not have post permissions for the TM section.

Thank you Kloppk

Found schematics in a training slide, these will have to do for now. Was hoping for one page schematic that could be printed off on a large printer. https://www.steelsoldiers.com/showthread.php?164142-MEP-831A-training-presentation-with-schematics

Title pretty much sums it up, I'm looking for MEP-831A Schematics that I can actually see. I have looked in the TM 9-6115-639-13&P in back where schematics are. When I zoom in to get a closer look, I cant read it. I have tried Google it, it just pulls the TM up. I have also checked the TM...

Sorry for taking awhile to respond. I haven't been able to work on unit since it started to make that noise. Been on and off sick since December. I should be able to work on it in April.

Ran for about 35mins until I went out to check on it, It was making a odd noise. Any idea what it could be, I could not figure out what it was. Edit: It did burn a lot of oil it took about 1 cup to fill back to full, after the 3 hours it ran the other day. https://youtu.be/0FopvA3Frp8
