Speddmon, I think the thread from yesterday took a quick turn off topic into lots of people making jokes, and other strange comments. Ike

Maybe there is some special use demand for them out there that we don't know about (I once read they were popular for lighting use in mines, but I can't see that being a big enough market to drive up prices), for most people they are paperweights, or parts units at best. I know we have rules...

Most common cause of high voltage on MEP-002a and MEP-003a generators is a bad output transistor on the voltage regulator board. These transistors will burn out if anyone tries to run the generator at below operating speed for warm up or shut down for more than a few seconds. if you look at...

Smart move, many people have snapped bolts off and had to drill them out pulling the blowers off Onan J series engines.

Unless you need them to power purely resistive loads (heating elements, incandescent bulbs, etc.) they are useless on the civilian market. Having said that there are some nice ones that look to have never been used that have shown up on GL lately complete with drum adapters, hoses, and ground...

papabear don't worry, it will probably sell to someone that has never heard of this board at an insanely high price :)

Nice, just wish it was not over 700 miles away, having said that, this topic is a rules violation, no talking about pending auctions allowed

You don't create 240V, just 120V and you gain less concern about load balancing, for the purpose of this example assume you have no 240V loads, just 120V appliances: 52 amps in 120V only mode or 26 amps in 120/240V mode. Now lets pretend you have 2 large window air conditioners that each draw...

1, don't over complicate things 2, the front panel outlets should only be used for low amp draw items, like a work light, or maybe a hand drill as they are often wired / rewired with small instrumentation sized wiring. 3, yes it is easy to switch between 120V only and 120/240V single phase, it...

They are both 10KW military generators, that is where the similarity ends. The MEP-803a was designed to fill the role of the MEP-003a, in much the way that the HMMWV replaced the classic Jeep, they both do the same sort of thing, but with more differences than similarities.

For anyone reading this keep in mind that by comparison commercial standby generators (not to be confused with those that are sold in big box stores) are rated using ISO 3046 ISO 5828 (along with others) which state: The rating applies to an average 70% load over 24 hours with a maximum of 200...

Well it looks like the output transistor on my MEP-002a has went out for the second time since buying it this year (no I did not idle the engine), when I started it today to try to track down whatever is causing the battery to drain I saw the voltage had spiked (156VAC regardless of adjustment...

These are just my personal thoughts, but I would have no concern about running a MEP-003a at 110% rated capacity for any foreseeable standby duty duration, and would have little concern regularly hitting 120% load and I am one that tends to be very conservative on such topics. The reason is...

The problem with the MEP-004a is that it was never designed to provide full load capacity in single phase mode, in theory a safe bet is that the generator end is good for about 70% of the 3 phase output capacity (a little over 2/3 of the 3 phase rating due to the added cooling capacity of the...

I would vote MEP-003a and try to work on your load management some, as the MEP-004a will be more prone to wet stacking since it is a water cooled unit (runs cooler), the other down side of water cooled is that water pumps have the bad habit of going out at the wrong time with little or no...

thanks will check and go from there Ike

What would cause the battery on a MEP-002a to drain over the course of a few weeks? (I normally keep mine on a battery maintainer, but somehow it managed to get unplugged and when I went to test run the generator the batteries were so low it would not start) thanks Ike

That is great news, let us know how things go from here. Ike

15w-40 here too

Well the bottoms do twist off and some of the guts do come out of the pumps so it is worth a try. Ike
