I personally enjoy working on my auction items as well. Thats pretty much why I buy them. I tinker in the workshop like a mad scientist.

Yes, minor failures is what I was thinking of. These sets are still bullet proof with a good mechanic around to sort out minor failures.

These sets are not new anymore...... That said they are no we’re near as reliable as a new generator set in my opinion. These used mep’s are really only good if you have high level mechanical abilities. Point is these sets are a poor start to a truly reliable set up. Anyway I love my mep...

I think it’s the governor. Has anyone rebuilt one of these governors? If so what could be wrong with it, I was thinking bad springs. The way it sounds and runs is like when you changed the load really fast on a perfectly working unit. The only difference is that in a perfect unit it quickly goes...

How much do the hertz change?

Also the fuel pump is working.

It ran for a couple hours at 12KW. I noticed that the rpm go up and down in a rhythm. I’ve seen other mep do the same thing when to much load is put on at once. But my 803A is doing it without a load and with. Also the diesel is brand new, and running other things perfectly. Thank you

I tried to use my IR thermometer and everything seems normal. I will take off the exhaust to see witch cylinder or cylinders are the problem this evening. Thank you

I did this as well. A whole tank full of the gum out brand. Maybe I should try sea foam as well?

It has run all the way up to 12,000 watts and held it. Its running heaters That add up to 12,000 for testing. Also like I said the problem is happening independent of load. Hopefully this info helps Thank you

Hi I’ve been lurking around the forum a few years and recently purchase a mep803-A.anyway Its surging a couple hertz and has produced large amounts of carbon build up in the exhaust in just a few hours. I have changed the fluids and filters and cleaned the switch’s . Hopefully someone can point...
