I redid a MEP003A 5+ years ago. Fresh rebuilt engine, new gen head...many other new parts. I had it running...making electricity. Then it has just sat. Anyone not real far away from se Iowa know these machines well and be interested in doing the fine tuning?

theyr're still holding fuel...nasty, stinky fuel. Acouple years ago I had a leaky tank on a MEP003a. I took it to a tank repair place in Pella, IA. Still doing great...but dang....cost me around $275. :-(

Another question comes to mind. Are there different rims available for these trailers? I would really like smaller diameter rims...and get rid of the *#@* split rims.

Great!! thank you!

Scored 2 mep003a's on trailer today. Look good...but...they have been sitting out in Iowa weather for 10+ years. Cleaning fuel tanks..changing filters. changing oil and filter. Anyone know filter #'s off top of head? I was able to get one engine to turn by prying generator thru the perforated...

I filtered WMO to 10 micron. 5 gal of WMO to about 30 gal of homebrew biodiesel. Felt like the Powerstroke ran better. 1999 Ford F250. BUT...twice it began smoking excessively. I quit using WMO and began adding seafoam and some other fuel injector cleaner products. Both times it took a while to...

Learning continues...arrgghhh... working on getting the Starter Lockout Switch adjusted. I followed the directions f. Got adjusting screw adjusted as instructed....started engine...diconnected wiring harness and adjusted set screw at .040. Turned unit off...reconnected wiring harness...

I was not getting any charge to the batteries. I swapped in a new DC regulator today and now batteries are getting a charge. This is the 2nd one I have had to replace in a 'fresh' rebuilt Melton engine.

I did find these at my local Fastenal store

Is the one under the shroud. Part # 2920-01-038-5252

When I took one of the other units I had to the electric motor shop, I was hoping they had an alternative to that VR....something more modern...more 'forgiving' if unit idled....but they had nothing

Got the 'new' circuit board in..fired it up...have ran it for 5 min or so...looking great!! Now..back to battery charging system...arrgghhh. getting 24.8 at the batteries...and it is holding. Thinking if it was working right, it should have started going up in the time I ran it. Got a new...

Trying to upload pictures...no idea why I can't get it to work on SS.

After the transformer swap, I fired it up...went well until small wisps of smoke on circuit board. CR7, CR8, and CR9 are fried. This was a MEP002a box going onto a MEP003a. I am now swapping in the MEP003a board. Is possible the frying transformer might have caused these resistors(?) to fry?

YES!!!!!!!!!!! It is a real pain lining up these bolt holes. I also took a sharpie marker and marked hole locations on flywheel and 'flexplate'. Also...have a magnet on a handle available for fishing a dropped bolt out of the bottom of the gen head!! I had one bolt drop and bounce back...

Well....took T1 transformer from my parts machine...a 002a...and installed it on the 003a. Fired it up...all looking great...until I notice a couple of small wisps of smoke coming from the circuit board. I will get out there later this week and see which resistors(?) fried. Thanks again...

Well...got it back together with the original 'sidebox'. Fired it up...Hz guage to 60...all right!! Plugged in a light I had close...it lit up. Went back to test charge going to batteries...when I saw smoke coming from control panel box. Shut it down immediately...opened the door...smoke...

Thanks!! I was thinking I had read they were the same. The 110v outlets on the mep 003a were missing,so I thought it easiest to just swap out the whole box. Thinking got me in trouble again! Hopefully I can swap out the outlets and install the original box...will see where that gets me.

I have been sputting a MEP 003a back together. I had a Melton rebuilt engine and a A1 gen head. I used the control panel from the old unit, but it was dead. Bad switch?? I didn't work to diagnose, I just swapped in one from a MEP 002a parts machine. I thought I had read they are the same. Unit...

Around the frame that the electric panels and fuel pumps bolt to, there are square, angled..spacers that go on the underside. What purpose do these serve and are they necessarry?
