And by complex it means replacing parts. The 802 or 803 shouldn't be paralled in their stock form. The voltage regulators as an example aren't designed for parallel operation and would have to be replaced with one that was designed for it.

That could explain the sudden disappearance of MEPs from the auction sites.

I had that happen on a Camaro. Rotor exploded and made a real mess.

You can browse fleabay for parts. The other option is to become a supporting member and post up a wanted list in the classified area. Some parts are generic and easy to find but some are not. If you need a relay, those are pretty cheap. Need gauges or one of the larger multi-contact switches...

I was able to find this one from the cross reference table of the NSN on digikey https://www.digikey.com/en/products/detail/orion-fans/OA172SAP-11-1TBXC/2620942 Has anyone bought one?

Has anyone successfully replaced the cooling fans on a MEP831 with something other than the OEM? I've been doing some searches and fans in the 150mm aka 6" range that fit are not that common. I'm in need of a couple at the moment.

Something else to consider is in the civilian world the 803 would be rated at 12.5-13kw. You don't want to run it quite THAT hard all the time but don't worry if you run it to 10kw for long periods. It should live for that.

With a modest amount of load management a 803 should handle everything you need to get you through an outage. I have an 803 here and its too much for my house. Can't keep enough load on it to prevent wetstacking. Now I run it only to charge batteries or run high current appliances. The inverter...

Right now there is a generator listed for sale on FB Marketplace that would work far better than trying to take one of MEP804/805 machines and forcing them into a scenario they were never designed for. I love these machines but I also know they aren't for everyone nor are they for every job...

Fuel, air, fire.. One of the three is missing. Fire and air are related since its a compression ignition engine. Do you have compression? Is air getting into the cylinder? For fuel its more straight forward. Is the fuel injection pump an injector working? You'll need to do some...

Yep. Not firing on all 4 is the first thing to check. Break out the IR gun and measure the temps on the exhaust manifold. Should be obvious. Don't run it any more than necessary for troubleshooting. In case there is something mechanical wrong. Minimize any possible damage that running it is...

I need to ask the obvious question - why are you wanting to do this? As an aside, the 004 and 005 generation machines can be wired single phase. It is a bit of work but possible.

Did you see they were close out? I ordered a few to keep on hand.

One thing you may want to do is check out the prices govplanet is getting for generators at the closest depot to you. Take the auction price and add 30%. That is about what a bidder will pay for a unit after fees and taxes. With that info you better judge the market conditions in your area.

These are prime rated sets. That means they can be run at their full rated load indefinitely. The rated load is 10kw. The set can produce more power than that. That extra should be considered reserve power for transient events such as starting an inductive load. The 52 amps includes the reserve...

Well, no. 52 amps resistive at 240v is 12.5 kw. The meter is calibrated for a 0.8 power factor. If you look at the gauge most of them have a red line at 80% which for a pure resistive load is your 100%. Edit If you have the voltage dialed down to 220v it’s 11.5kw. Either way it’s over 100%.

Check and see how much fuel you have returning to the tank with it not running in prime and with it running under some load. It’s ok for the return flow to drop a little but you should still get a nice stream back to the tank.

A 100 amp contactor will handle ~36kw at 120v which exceeds the 33kw capacity of the load bank.

The answer isn't really standardized since how much load and how long at each load should be based on what you are trying to do. If its routine run I'll do 15min each at 25%, 50%, 100%, 50%, 0%. If I'm in a hurry, I'll warm it up a bit then 50% for 15 min and 100% for 15 min. If I'm clearing...

Any generic 100A 3 phase contactor that fits should solve the problem.
