Howdy, Cleaning up some threads with info. MEP-8xx Fuel Return Line MEP-8xx S1 and S6 switch variations MEP-802/803 relays

MEP-8xx Fuel Return Line Howdy, The MEP-8xx series of generator all use diesel fuel return lines. After sometimes sitting with no fuel, or heat cold, no-use etc... they start to fail. The main issue is the lines start weeping fuel. NSN 4720-01-483-6467 part N20353.5 HOSE, NONMETALLIC...

Howdy, Both the MEP-802A and MEP-803A use the same relays. The relay are all the same, EXCEPT, the one on the far left. It is SPECIAL.:wink:

Howdy, The bakelite version would be the better unit. It has a metal stab which the turn knob is mounted on. The Plastic version has a plastic stab pin which some users have found it can snap off and break when turning to aggressively. I am sure Guy will come along and let us know the proper...

Howdy, A military power plant is for 100% uptime for electrical service. The smaller dual 5kw, and dual 10kw power plants do not have the smarts for parallel load sharing. The dual units are meant for a quick easy transfer of power between units. That way the oil and filters and such can be...

Howdy, So many ask, but do not know. They do the same function. Pictures of the S1 and S6 switches. Plastic switches Bakelite switches

Howdy, Fix your generator to the best working shape you can. Exercise your generator for a hour or more with load. Keep batteries charged. Have the steel soldiers forum ready for parts and pieces.

Howdy, As much information you can supply. Pictures, age, did you ever see it run? What was said about the unit from the auction? Since you have gotten filters you already went through this thread. MEP-802/803 Filters and Parts View a quicky video here MEP-80x startup routine

Howdy, The new AMMPS have built in parallel ability. It also make it possible to load bank more than 1 to many units using parallel loading. Or, in real life, 2 x 5kw units working as a 10kw unit. Or 3 x 5kw units working as a 15kw unit.:cool:

Howdy, You know the MEP-803A can handle a lot of load. Look back at my thread with the load bank. Acquired a Military surplus load bank (running MEP-803A hard) Watch the video through the end. I have the unit handling 67.2 amps per leg single phase 120/240 on the load bank. Watch the...

Howdy, Looking good.[thumbzup]

Howdy, I did not want to make it look like a disco floor. I also am not trying to watch colored coded meters. They are all important to watch. ;)

Howdy, After replacing so many screws with stainless steel parts. I wish on the 2007 unit I changed all the nuts to RIVNUTS. But, that won't happen since I used all stainless steel bolts and nuts with lock washers.

Howdy, All the touch -up paint places are still looking good after running a bunch of hours since painting.

Howdy, MEP-8xx generators have fuel return lines. When you see the hoses weeping, you will want to replace the lines. This is the proper 3.5mm ID which pushes on the hose barbs and does not leak. I repeat = fuel return line... very low pressure line which goes back to the fuel tank.

Howdy, Now after collecting a few green things, I really like having a charger which I can move around. I simply throw it on the slave port and walk away. Since it's a smart charger, I can leave it there a week or month or whatever.

Howdy, All the optima batteries which I have purchased have been working good so far. I just make sure I abuse them a little in the first week discharging and then re-charging them a few times to make sure I can rely on them.

Howdy, I also found out the Depot rebuilds and the new 3rd generation AMMPS all start out with John Deere Break-In Plus oil. (y)

Howdy, That is part of the problem. They did not use stainless steel hardware. I have replaced most screws and nuts. The newer units started using caged nuts. That really makes it easy not trying to hold a wrench up above the air filter. It also speeds up the time to take panels off and on...

Howdy, No Loctite is needed with the proper screws and nuts. MEP-8xx stainless steel screw information The screws with the lock washer K-Lock nut holds nicely.
