Ok, I will order one. Also I tried to reset the rod and adjust voltage via speed screw - got it to 176 +- but now generator will not even run cold.

Hi DA, I ran it again today, trying with a start on the battery after some trickle charging. No start on the battery and tell tale starter click, no joy. I then recoil started it , and the idle surge / instability was apparent immediately, so I shut down. Disconnected battery and recoil...

Hi DA running with load: JH GF Load input AB AC BC 20.6 27.4 1.05 190 188 184 16.3 27.6 .9 182 178 181 10.3 26 .9 unstable after 10 min

I just RTM'd I'll be back with the other voltages needed according to corrected MEP 831 training schedule.

Generator starts fine, and runs very well until it warms up and then the issue replicates, I would call it idle surge, here is the video and the data. The voltage was steady but gradually dropping as engine warmed up, at about 15 minutes in, I started recording the position of rod as well, the...

Hi D.A. yes I will do that, do you need a video to diagnose or just the voltage readings?

Hi D.A > running on mechanical or electronic governor? I re-read my post, it was not that clear. I did disconnect the battery and restart after fresh fuel and full tank, the stumbling was with electronic governor engaged and no connection to battery.

Got it up and running, It took about 3 fills from fuel filter to injector to get it going. I had it running very nicely for about 20 minutes, then shut down and connected battery and restarted (again by recoil) and measured voltage on battery while running (24-26) Maybe there is hope for it...

I will try this tonight thank you very much

I see from a separate thread diesel addict suggests gravity feeding the fuel prime - where do you suggest I tap in to do this?

Hello, I have bought a few MEP831A's they were tier 2 resets and stored in late 2013-2014. I have the original battery which is testing at 14v. My intelligent charger does not want to charge it and throws a code. Question: How do I recoil start this with fresh fuel ? I have emptied bowl...

Hi everybody, You have a great forum here in steel soldiers, I have learned alot from reading so far. I am the proud owner of some mep-831a's I am in the process of changing oil, oil filters, and fuel filters, units LOOK to be in great shape and I will try load testing. Batteries are all...

Tks sir, I pm'd you.

As a new owner of a couple 831a sets this thread is fantastic, afghan keep it up!

In case it helps anyone, or could be added to the sticky on front page, I found the cheapest oil filters 'sleeves' for the 831a from ace marine diesel 5.76$

Dav5, have you found a good source in canada for parts on the 831a and the 803a. I just bought some....:shock:
