I bought several 002A and 003A generators that were missing the original 3 section military canister type fuel filter assemblies. I bought several two section Ford tractor fuel filter assemblies off ebay for around $30 each. It mounts exactly as shown. The first section is a water separator with...

I have been buying and refurbishing 002A and 003A generators for several years. Most of my "real world" testing has been done with 003A's, since I have two of them. I also have a 002A that I have never tested except on a resistive load bank. Several days ago I decided to see what my 002A would...

When it comes to repair the 002A and 003A generators were MUCH MORE user friendly than the 802A and 803A. I have at least one of each type and I speak from experience.

Voltage adjustment rheostat is wire wound and should read 0-1000 ohms as you turn the knob through its arc. I guess it can happen but I have never seen a voltage rheostat open up.

"Engine struggled for a second.....then engine recovered to full RPM with no output voltage". This sounds like a current overload that the 5KW generator could not handle. Let's check the obvious and simple stuff first. Did the output circuit breaker trip? This is the main breaker to the left of...

Dirty can mean a lot of different things. I refurbish and sell 002A and 003A generators. I have good success cleaning them by spraying full strength Purple Power all over the unit. I put the Purple Power in 2 gallon pump up sprayer. After letting it sit maybe 15 minutes and depending on the...

Put one of the heavy duty knife switch battery cut-off's between the two batteries. When it is time to charge the batteries use the two 12V chargers and open the knife switch. When you are finished charging, close the knife switch for normal operation. This will make isolating the two batteries...

I think once you get to know your 003A's you will love them. As far as load testing I use electric water heater elements immersed in a plastic 55 gallon drum of water. A 5500 watt and a 4500 watt element will give you a 10KW load.

I have several MEP 003A's and a MEP 803A. Either will easily run 10KW, When I increased the load both ran at 12KW. When I increased the load to 13KW the 003A kept going but the magnetic circuit breaker in the 803A opened. My 003A even load tested to 16.5KW for a minute without tripping. The 803A...

I hope the original poster was not offended by those of us (including myself) who expressed possible concern over the 003A exhaust system he showed. If so that was not my intent. As explained in my post and by others, getting rid of HOT exhaust gasses can be a bit more complicated than just...

While in theory a small exhaust pipe may be adequate especially in this situation, in the real world a larger exhaust pipe (up to a point and with diminishing returns) will offer less restriction to the hot gasses exiting the engine. A larger exhaust pipe (up to a point) will result in better...

Interesting concept and I hope it works well. In order for any engine to perform properly it must be able to breathe. That means the engine must be able to freely "inhale" and freely "exhale". The exhale part is the exhaust. If the intake air, fuel or exhaust is restricted the engine cannot...

I have a 4200 sq ft house located in the middle of a 700 acre farm which is the only residence on and is located at the end of a 1.5 mile long dedicated power line. During the 2014 ice storm several of the power line poles broke off and I was without commercial power for 96 hours. I used my MEP...

Sealed wire wound "pots" like the voltage adjust "pots" on the 002A and 003A are very reliable. They should read 0-1000 ohms as you turn the shaft. I had one that was squirrely. I drilled a 1/8 inch hole in the side and liberally squirted DeOxit into the "pot" and exercised it many turns. That...

I just checked a VR that came out of a 002A and a VR that came out of a 003A. There is no difference in the number of components. All resistors are the same value and the same wattage. Ditto for the capacitor values and voltage ratings. The 3 transistors are the same. There may be a difference...

Thanks Isaac-1. As soon as the Q3 transistors arrive from Mouser, I will swap out Q3 with a new one and see if the old VR board works. Of course to test it I will have to reinstall it in the 003A I took it out of. This is one of the generators I am refurbishing. Of course if the repaired VR...

It was the VR board. I removed a working VR board from my personal 002A and installed it in the 003A I bought at a GSA auction that I am refurbishing to sell. I hope the VR boards in the 002A and the 003A are the same. Voila! The voltage comes right up to 120/240 each time the generator is...

Thanks for all the replies and suggestions. I "exercised" the two multi-turn pots on the VR board. That did not help. Earlier today I ordered a couple of VR output transistors Q3 from Mouser. When they arrive I will replace Q3. Hopefully that solves the problem. If not I will replace the VR...

I have a MEP 003A that the output voltage is not stable. Most times when started the voltage is 120/240 as it should be. Occasionally when started the voltage goes to 150/300 and stays there. When I shut the generator down and restart it sometimes the voltage goes right back to 300+ and...

I have a MEP 802A and assuming the 10.2 amps 3 phase you stated that is required and assuming the ECU will run on 208V instead of 240V, the 802A will RUN the ECU but it may not START the ECU. What is the starting or inrush current of the ECU?
