Mep-803A Diesel Gen

[rlegare44]

Have an MEP-803A. Can start it with both the start, prime control on panal, and with the dead crank switch but cannot shut it off without pinching the fuel line to cut off fuel. Not getting any power to the 120 outlets. Cannot get acceleration from the frequency adjust knob. Only half of the guages on the panal show activity. HELP!!

You should not be able to start the machine from the Dead crank. only turn the engine over

Have you given it a visual check to see if everything looks to be in place or if anything looks disconnected or missing?
Is your Fuel solenoid missing or the arm disconnected?
Also, when starting it from the Dead crank, your electric fuel pump should not run, if it is, perhaps you have a wiring issue that is powering things that shouldn't be getting power from the dead crank.
Even the e-stop button doesn't shut it down?
I think it's going to take a bit more investigation to get us moving in the right direction.... What about posting a video so we can see more details?
I'd like to see what the fuel solenoid as well as what the control panel ( gages ) are doing when you start it from the dead crank.

You need to help us a bit.

1. Have you seen this gen set when it worked right?
2. If so, have you made and adjustments, or repairs to it?
3. Like Ray mentioned, so video of this set in operation would help, as well as maybe a bunch of pictures take of the inside of the control panel and the engine doors.
4. Have you downloaded the TM's for this gen set, and maybe read some of the operators TM on how to start and run it?

I will attempt to run it again possibly Monday 29th and make a video of starting and trying to shut it down. Had it for four weeks at a diesel place but I don't think he knew what he was doing. He rebuilds diesel pumps but I think this was a liitle too much for him. Have it back now and will try myself with the help of you guys. This is kinda wierd cause I can prime, and often start at the control panal. Cannot get and reaction from the frequency adjust. Moves the cable on the solenoid but nothing happens. Once it starts the only way to shut it down is pinching the fuel line to cut off the fuel. Some of the guages on the control panal read and others don't when running. Was told by one the the frequency level needs to rise to get hem to react.
Thanks.

Ross brought the generator over my house today, and we managed to get it running just fine!

Injector pump rail was jammed, and one or more injectors weren't lined up. Took a lot of patience. The second after we called it for the night and he drove away, I finished bleeding for the 4th time and it fired right up. Called him to turn around and come get it.

Problem solved and never would have been able to correct without the help of one young man who offered to help with N/C. Problem was the arm within the pump, driven by the selenoid was not moving some of the injectors. With injectors taken out and repositiong the the arm, reinserting the injectors with the injector pin properly positioned to fit into the arm, bleeding fuel lines bottom and top it started and runs great with all controls operating properly. This young man is a self trained, HAVC installer, elctrician, and building his own beautiful home from scratch. I was so impressed with his talents, especially with all you hear about the younger generation these days. Thank you Tommy soooooooooooooooo much. And thank you all on this forum for rapid feed back.

Thanks Ross!

There's so many people here generous with their time and knowledge-- I'm always willing to pay it forward.

For the record, I'm ashamed of my generation.
