What have you run with your MEP003a?

[robkiller]

I have run an electric oven with 2 electric burners on at the same time as the electric dryer and the other normal things running in a house hold like lights and refrigerator... I dont know if thats good or not but if i kick on a another 2 electric burners it tries to kill the generator.

What do you think is that a good or bad result?

What have you run at the same time?

I have loaded the heck out of mine. How many watts are the electric burners? It will sound different running under a heavy load but it should provide 12k watts without stalling or bogging to the point you start dropping voltage.

 

[Rapracing]

The dryer I believe is about 3500 watts and the burners on high probably about 1500 each. Not sure what else may have created a big load but sounds like it may not be up to snuff. I am sure others will reply. I could be out in left field.

My 002 runs my house, deep well pump and one day my wife actually turned on the electric dryer not realizing that she probably shouldn't have. It jumped to about 105% but never missed a beat.

 

[robkiller]

I found a web page that indicated that the electric oven is about 3,000 watts, elements 3,000 (1500 each) Cloths dryer 4,400 watts. This is what i pulled of the net i dont know how true it is but if they are close i guess it is running with everything else in my house around 11-12k.

But i am also looking at doing a few things to make sure the gen is healthy such as compression check/glow plug check/ injector check.
You guys are a better resource then anything so that why I am checking with you guys.

it just doesnt sound right to me but who knows. what does your ammeter say? % of load? if you cant peg the gauge then the best thing you can do is pull your injectors and have them done. out of 4 generators i have done every injector and there hasnt been one even close to being right. springs squished inside those things for 30+ years are bound to not be in spec anymore.

to give you an idea, i run every light in my shop. thats 29 4 tube ho flourescent fixtures, a 3hp tubaxial fan in my spray booth and with all that on it still kicks over my 7.5hp compressor which is around 38a running and 60-70 at startup.....atleast going by the specs. that will peg my ammeter beyond the readable scale. the compressor kicks on and the gen gives a quick burp for a split second and its back to full rpm. it will run pegged like that for about 10 min until the main breaker on the gen finally pops. just judging by how it runs i would guess if the ammeter went higher and the breaker didnt pop then i could probably hit 150% before the eng started to shut down.

1789sqft home I can run all lights and fans, fridge air compressor (110 volt) and freezer at 25 percent load. with ac running 50 percent load... my stove and dryer are gas so I cant use them for load.... my mep developed a skip and smoking when load testing from a bad injector so you might send them out for service... my injectors are in the mail and when I get them installed I will inform if it fixed my issues but it sounds like you have the same problem I was not making full power..

 

[robkiller]

Who did you guys use to fix your injectors? How much was it an injector? How do you know if an injector is bad vers something else?

 

[TucsonVTXF]

for me my mep ran great under no load but when I did my first power run I made 50 percent power no problem but as I increased load a sputter developed like a miss... my cylinder temps were two the same... one 50 degrees higher and one 40 lower... that coincides with the repair reports for what the ejectors were popping at... as for who can tune them for you search the threads on here, I don't want to violate forum rules on here if there are for classified adds..

yes jerry is your injector man!! very reasonable and quick

TucsonVTXF,
Your injectors are on the way back to you. Thanks to all.

So at this point i need to rule out injectors vs compression issues. From my understanding the injector issues can be seen with the engine cutting out cylinders (sputtering) and how warm the cylinders are using a temp test. The compression issue it seem the only way is to test compression and since i dont have a way or know of a way to get this done it looks like I will need to test injectors to make sure that is my problem. Any thoughts? I just want to make sure before I send my injectors in that they are the problem and its not the compression.

 

[Jimc]

mine ran great with one frozen injector and 3 of them 350psi low. i would never have known there was a problem other than it wouldnt put out over 90% power. it wouldnt run the rated load. i thought my ammeter was bad or not set right. i would never do a generator again without having the injectors gone through, even if it ran good. compression is always a possibility but injectors are much more likely.

 

[robkiller]

This is what i will do that is a great point. I will order the kit to fix my injector pump leak and while its down for that send my injectors off to be re calibrated and or fixed. Storeman you will be getting my injectors in a week or so. Thanks everyone.

 

[storeman]

I'll be looking for them.

just received them today!!! thank you!!!! and the pressure settings on the injectors were related to my exhaust temps!! my 1300 and 1600 psi were about 200f the 1100psi was running 400f and the one that wasn't popping was about 150f

installed my injectors and new gaskets last night and ran the unit unloaded for 45 mins today to get it up to temp and leak check my lines and new napa oil pressure switch.. my #1 and #3 and #2 and #4 are running the same temps and are about 20f different from the other... overall the unit sounds like it got a tune up... please keep in mind I have not pulled a power run yet but will do it Sunday or Monday when I show the girlfriend how to set and run the unit and connect it to the house...

 

[robkiller]

Ok so i hope i did not make a mistake. I took of the injector’s wow that was not easy. I hope i can get the injectors back in without leaks every place i did something. My fear is i went from a running unit to what could be a none running unit when i am done.

So i have the injectors out but how do you get the air cooling fines off? I am going to send them in to be re calibrated and all but those need to come off first and i cant get any of them to come off.

 

[jamawieb]

What I do is spray between the injector and adapter (cooling fins) with wd-40, then lightly tap the adapter with a hammer. It will slid off with little force but in one case I had to really give the adapter a couple of good hits before it let go. Be careful with the adapter because it is aluminum, and make sure you do not over tighten when installing.

 

[Munchies]

If wd/liquid wrench or kroil wont work with a hammer or some big channel locks, put some heat to it. Should bust it free pretty easy with heat given its aluminum in a steel bore with no threads.
