Most likely a flimsy battery tray or could be a flimsy plastic terminal cover. They were generally included new on units, but are worthless and could have been a way to charge uncle sam for useless cheap things with overpriced parts.

Hello,
Please contact GMG customer support via our contact form on our website. We will facilitate reprogramming your board. Our manufacturer has relayed the following to us:
“This would be a Version 3 Special. About 1 – 2% off all 805B/806B Generators have this odd configuration. This means the Screen will be turned off and on after each start to reboot system and it has the Excitation of Version 3. We can reprogram the board.Turn around is usually 48 hours once we receive the board.” GMG will pay for roundtrip shipping, but we need to confirm your order and ship from/to address. Thanks.

[GMG]

This is most likely a MEP806A or MEP806B generator. Look in our free manual section for those manuals.

Voltage adjust typically only enables single-digit adjustments. There is a bigger issue with voltage regulation going on.

[GMG]

When hooked up correctly, did you have voltage at the solenoid? If not, you need to figure out why. Could be a safety issue (oil pressure circuit or other safety circuit). Not sure what you mean by panel switch off (the button kill switch?). If that is off, you should not be able to use the generator. If you can, you have some other wiring issue and perhaps someone has been inside the unit before and something is not wired correctly.

[GMG]

Yes a great generator. Personally, I have a MEP002A, which is the previous generation, but same size as the MEP802A. It really depends on your load needs. I use my MEP002A for whole house, but do not have every electrical thing on in the house when there is an outage. We also offer automatic start kits for all military units.

[GMG]

Bad pump or bad pump installation. Assuming fuel gets to pump, have you cracked the lines just after the pump and before injectors (to rule out clogged/bad/seized injectors). If so, your pump most likely needs to be rebuilt. We sell all the parts to rebuild or can rebuild yours for you. All this assumes that the pump is installed correctly and is actuated by the gear.

[GMG]

No fuel, no fire. So yes, it can. But we have no idea what type of generator you have. If 002A or 003A, you have central injection pump. Could be pump, could be injectors. If 802A, 803A you have multiple pumps and injectors. You need to isolate which injector or which pump is at fault. In addition, you need to solve your engine problems before electrical problems. Too much to diagnose at one time. If the voltage and frequency are jumping around but the engine is super-steady, then you have other electrical issues. You need to isolate the possible fuel issues. If you are running your generator without FIRST cleaning and replacing all filters and blowing out all fuel lines, you may have sucked crud into injectors/pumps.

[GMG]

You need to ensure you are using an external meter and not the on-board meters to ensure that you are reading correctly. If there is more slack in the throttle cable, you may need to adjust the cable itself. Lubricate the linkage well and check the entire throttle cable assembly. These cables can break or become frayed.

[GMG]

Unfortunately, it was difficult enough to locate the kit from Europe. I would try searching the Internet for the make and model of the series of injection pump (i.e. not the MEP701A or MEP016B model). We have updated the product description with some informative diagrams and links. You can also see this video that might help (albeit the application is not identical): Bosch PFR1K80A505 How To Video Here is another related video of the Bosch PFR pump.

[GMG]

We do not recommend non standard configurations as the manuals then become useless and the generator could cause a severe injury if someone doesn’t understand the non-standard configuration. We would recommend getting a larger military unit that supports this this higher voltage in 3-phase as a standard feature.

[GMG]

I do not believe so.

Yes, we have generators. Currently, the MEP802A (or larger MEP803A) are common in the 1800 rpm range (aka low rpm). Assuming you would want to automatically charge up a battery bank as well as provide peak loading (e.g. large tool work or needing to power a load that goes beyond your day to day battery bank), we would recommend the MEP802A. The larger MEP803A would consume quite a bit of fuel for the load you would place on it (small for battery charging on an ongoing basis). Military units under this size (5KW Continuous-Run) run at 3600 rpms (e.g. 2KW and 3KW size). They can be excellent choices, but will not have the longevity and ability to handle a typical home if for some reason your battery bank is exhausted or down for maintenance. But if fuel efficiency is critical, smaller units may be options.

[GMG]

You need to consult an electrician. You need to wire it for 120/240. You can’t just wire it for 120 (unsafe). Bond neutral and ground and you MUST use grounding rod at the generator/trailer. 2 hots, 1 neutral and 1 ground to box. The unit can operate in single or three phase. You need to make sure settings are all set to single phase 120/240.

Again, consult electrician.

[GMG]

I doubt it would hurt, but we recommend 15W-40 engine oil (conventional), unless you are in arctic conditions or very hot conditions where more specialized and straight weight oil would be more appropriate.

[GMG]

A series cheaper than B series to own and operate as they have less electronics, but we can’t really estimate what is wrong or what it will cost. I think you need to assess whether $1,000 worth of parts and labor would kill the deal or not.

[GMG]

Sorry, we do not at this time, but there might be on the WWW. Try searching for it on YouTube or similar.

[GMG]

This is a 400Hz unit, not a 60Hz unit. But this sounds like a voltage regulator issue. Use a multi-meter for all testing. Do not depend on the on-board meters.

[GMG]

This should be in the manuals. Look at the battery diagram and grab the NSN number and/or part number. You can cross the NSN number to manufacturer numbers via many NSN databases like: https://www.parttarget.com/

[GMG]

Most loads can run on 208v or 240v power, so you might not have to convert. Check the nameplate of all of the loads you want to power. The key is to balance the loads on each leg. This is key for safety and optimizing the efficiency of your generator.

[GMG]

Battery group size 51R.

[GMG]

You really need to get the manual out and begin isolating the electrical side of things. There are many items to troubleshoot and the manual will help. Age and hours and other issues are really meaningless. If a generator sits for too long, windings can corrode; diodes corrode and a host of other electrical components can corrode. So each major circuit needs to be tested and troubleshooted. The manual is the place to start.

[GMG]

Injectors could be bad or clogged. Governor solenoid could be bad. I am assuming that you have cleaned and confirmed the entire fuel system is good and that you have fuel spitting out of each injector line. Assuming as the unit runs. Governor is our best guess.

[GMG]

Sorry, but we do not have any guidance here. Not that it is impossible, but there is no quick answer. This requires replacing certain parts and rewiring. We personally have not done this, nor would we for a client.

[GMG]

Voltage regulator issue, most likely from idling unit below 1800 rpm. These units must be run at 1800 rpm (=60Hz).

[GMG]

Hz is directly proportional to engine speed. Have you checked the convenience outlet with a multi-meter to rule out a bad meter? If not, do so. There is a fuse on the convenience outlet that you should check as well. You didn’t say whether you can still use the convenience outlet.

[GMG]

The filter we sell is milspec and will fit. The Fram unit comes with the correct gasket that will fit the MEP002A-MEP003A.

[GMG]

Once the genset is fully warmed up, you should then adjust the frequency adjust cable (aka throttle) to get the unit to 60 hz or 50hz. The governor, assuming it is working properly, and fuel stop solenoid, will take over from there and adjust fuel flow as load is increased or decreased. You DO NOT need to monitor.

[GMG]

Check the voltage on the 3 phase 5HP machine. It is usually 208 volt, not 220v. The specs of the motor should clearly ID the following:
voltage (for 3 phase, 208v is most common, but sometimes it will show 208-240v as being an acceptable range.
frequency (our units are 60 Hz, so make sure the specs show 60Hz or 50-60Hz as being an acceptable range.

3 phase motors will last longer, can be reversed with a switch, and have less vibration, so 3 phase is a stronger motor.

Yes, having the utility install three phase power to a residence is typically cost prohibitive if available at all. Many places do not offer three phase power options.

A 15 HP motor would be around the limit for a MEP003A or a MEP803A military unit. Just ensure that the Hz, Voltage, and Phase all match.

[GMG]

You are using a multimeter to confirm 60Hz? Have you looked at the manuals for default settings for the CIM. Check out our free manuals here: https://greenmountaingenerators.com/manuals-and-support/mep806a-manuals/

There might be default configuration settings to be programmed. Does the readout change if you adjust throttle? Just need to confirm if this is static or moving with the RPM.
