Looking for replacement and diagnosis of burnt IC on board - let me know if you have a replacement and if anyone knows the reason it failed. Thanks,

So we are trouble shooting the board that control the fuel solenoid relay and also excitation. Our engine runs well when we bypass the control board for the fuel solenoid but we lack the DC power light, solenoid connection and excitation. Attached are photos of the board and a tag - can anyone...

So we got this DRASH unit in and it is trashed. WTF - I want to ask but probably don't want the answer - how can a machine with 27hrs on it get disassembled and trashed? Don't answer - we don't have time for that. Here are some photos - what I need to know is what is missing from the Isuzu...

Anyone know why late model 2009-2010 MEPs are being surplused out when only five or so years old? Typically they have a 20 plus years surplus sale time frame. I'm thinking of the MEP-903s that were surplused early because of noise and other design issues. We did six of those 903s and they all...

Interesting reactive load bank but can't find any documentation. Anyone? 60kvar and they talk reactive - so inductive loads? oooo,aaahhh,ooooo,,,ahhhh

Trying to cross reference is MEP-004 and MEP-006 can use the same voltage regulator assembly. Part number of unit I pulled from MEP-004 was 30554-70-4145 Unit from MEP-006 is a 30554-70-1367 Darn close and maybe only a version or year difference in part number - anyone know for sure?

Ok, stuck trying to open injection pump on MEP-003. Need to verify pin is in place or find other internal issue. how do i remove the distribution assembly from its housing

Ok, here is another tough one. We have a mission critical MEP-004 that starts and runs fine, so we power up the loads and it runs perfect for roughly 20-25 minutes then slowly drops to idle then eventually dies. Work done: complete fuel system cleaned (like three times), pulled float switch...

Anyone here of a new policy of pulling bottom radiator hose and oil filters off perfectly good generators? I've not seen this before but do know that in some cases fluids should be drained prior to shipment. Pulling hoses and filters seems excessive. Let me know what may be new policy or is...

Can anyone confirm that a Wix 46272 & Napa 6272 Air Filter is a direct replacement for the NSN type air filter for the MEP-004, 005 and 006 ? Those NSN air filter are getting pricey and I saw that someone used a Napa 6272 which is easily available - just want to confirm before I buy a case!

Anyone out there with more of these 20kw Hanco units? Looks like helicopter or air drop diesel generators? Engine: Hatz 3M41Z Hanco Generators are made by Southwest Products

Ok, so we go thru MEPs regularly so I asking for advanced help here - likely on fuel solenoids. We have a MEP-004AAS that ran well three years ago, then the check valve clogged so we fixed that a year ago and it ran fine. Then we pulled it out this winter and no start. Cranks fine, we cleaned...

My M1010 will start and I use a dead head relay and have checked all glow plugs so it must be a fuel issue. Engine cranks for 10 plus second before it fires. My M1031 would fire right away - hardly cranked at all. Should I be concerned? Truck runs great but seems to crank longer and slower...

Picked up a nice set of 2007 Chevy 3/4 ton mags with hub caps that use plastic bolts over the lug nuts. Problem is the 3/4 ton lug nuts don't work on the M1010 - so where do you find the right lug nuts to use these nice hub caps or is that not an option. I've not checked if they fit over from...

New thread to detail the voltage regulation process from DC excitation to regulation. Current issue with MEP-002 I am working on to troubleshoot. 1. Upon starting the engine - DC excitation happens and voltage with Start position (so DC voltage is working to start the electromagnetic process)...

Ok, we took the M944A1 our Friday (been sitting about one year) and ran the generator for awhile and the big cooling fan kicked on a couple times. Then we noticed the transmission temperature gauge was pinned at 325! Today (Sunday) we took it out for a drive and same transmission temp reading...

Any push an MEP-006 to see how many horsepower water pump one will start?

First military generator I've sold to get returned - customer tells me he moved voltage board to run a 480 pump and the stator and voltage regulator burned up. Wants his money back....unfortunately I've already restocked my inventory, so I really want to find out how and why this happened. I...

Question: how to tune the mechanical governor build into the injection pumps on the various generators - MEP-004, MEP-004 and MEP-006 among others I'd expect. Under load the weight move slower and the injection pump has two mechanism to hold RPM - the weighted mechanical governor and the auto...

Ok, I need to replace a main contactor so two things would help. the complete assembly part number and of course someone willing to sell me one. Checking the parts manual I get all the break down in detail of the all the little parts but I just want to buy a complete and working assembly. Do...
