We live in a crazy world! I thought warm diesel engines should start easier than cold ones?! “My Generator Starts When Cold, But Not When Hot!” That is a true statement and remains true. The problem might not lie in the engine itself or the injectors or the injection pump or anything related to the […]
We have had requests for diagrams for the MEP002A and MEP003A wiring. In this post you will find 3 high resolution photos of a new Control Box that we have in stock (yes, it’s for sale;-). Hope this helps you with your electrical needs.
Below is a great video that concerns itself with answering this oft-asked question. Many military generators are only configured to output three phase electricity, especially the larger units including the MEP004A, MEP005a and up. Note that the MEP002A and MEP003A models output single phase 120/240V single phase power just fine and are not the focus […]
We get this question A LOT! Some customers buy new MEP002A or MEP003A re-manufactured engines from GMG. Some buy our refurbished generators complete. In either case, we recommend a Break-In period, especially for re-manufactured engines. For refurbished generators, we recommend an early oil change in the 50 hour range (vs the normal 100 interval) to […]
Is your generator (MEP002A or MEP003A) sputtering? Is it coughing smoke in a rhythm? If it is, it could very well be time for new injectors that will improve the performance of your generator dramatically. We now stock this very difficult to find injector. It was made by Onan in the early days and was […]
Two methods for field-flashing generators, one using an existing 110 volt source, one using an electric drill – by End Times Report Home generators in storage can “go flat” or lose their magnetism. Then they will not produce electricity, even though the small gasoline engine turning them is running just fine. There is a simple way to fix […]
One of our recent customers had a small scare with their new generator. Nothing dramatic, just puzzling. The engine started normally and everything seemed 100%, except for one issue: no electricity was being generated to the main terminals or the convenience outlet. Frustrating to say the least. The customer and GMG tried most of the […]
We have finally assembled what we believe is a relatively exhaustive list of past and present generators used by the US Military. On this page, you will also see links to two versions of the: STANDARD-FAMILY-OF-MOBILE-ELECTRIC-POWER-GENERATING-SOURCES-GENERAL-DESCRIPTION-INFORMATION-AND-CHARACTERISTICS-DATA-SHEETS-MIL-HDBK One version was published in 2010 (MIL-HDBK-633A) and one published in 1998 (MIL-HDBK-633). Both of these manuals have very […]
We have them. They aren’t cheap, but they will help keep your unit 110% in the winter and cold starts. These will also help save your starter from over-working (same goes for your batteries). Follow link to purchase MEP-002A and MEP-003A 24v Glow Plugs.
Many military generators have check valves in the fuel line system, often immediately after all of the filters, strainers, but before the injector pump. This prevents fuel from flowing backwards in the system and also helps the system hold its prime. The MEP-002A and MEP-003A units have a check valve located after the third filter […]
How Noisy Are MEP002A and MEP003A Military Diesel Generators? The Same As Honda’s Best Worksite Unit!
GMG gets this question a lot! Many opinions can be had about the noise level of MEP-002A and MEP-003A diesel generator units. To protect your hearing around any engine or machinery, wear hearing protection! It’s cheap and your friends and family will thank you when you’re not screaming at them or the TV is blasting! […]
This article describes common power generation connections and discusses the use of power transformers. This is a scanned article and there may be typos and some odd images. We tried to scan and convert this so that it is more accessible on the Internet. Please see all the figures and pictures at the end of […]
This is a great example of a MEP003A installed for home use. The unit is place on high ground that will drain well. Then the entire area is covered with crushed stone to aid in water transport and to minimize mud kicking up on the unit. 4 modest sono-tubes are sunk in the ground to […]
Most of the time units are purchased by GMG without milspec batteries. If this is the case, we do not install milspec batteries as they are prohibitively expensive and quite difficult to obtain. We find very very durable civilian replacements and install 2 brand new batteries. Below are the specs on the batteries we use […]
These manuals are for servicing your Ambac M-50 Fuel Injection Pumps for your MEP002A or MEP003A units. Not that we recommend that the average person attempt to service or rebuild your injection pump, but we want to provide all of the manuals we can find for you. GMG will begin to offer a rebuild program […]

There seems to be a lot of confusion about the voltage standards for motors and why they are structured the way they are. There are, of course, two broad categories of motors, AC and DC. The voltage standards for these two decidedly different motors are much different from each other. It will be the goal […]
This chart estimates diesel fuel consumption for a generator based on the size of the generator and the load at which the generator is operating. Please note that this table is simply an estimate. Many other factors will affect the fuel efficiency of a diesel generator including design, fuel quality, air quality, and frequency of […]
