MEP 805B won’t shut off

[JW929]

Well I was out of town and my wife fires up the generator. When she went to shut it off, the generator would not shut off. She tried everything and eventually it ran out of fuel. Two questions, 1. What would cause it not to shut off and 2. Where is the injector pump primer lever to prime the system before starting?

1, Electronic governor incorrectly installed, first guess

2. hand primer is on right side on fuel pump, near fuel filter. If you are repriming, crack fuel line at pump to help purge air

 

[JW929]

Thank you! I’ll check both out tomorrow.

Post up what you find. Or take photos too

 

[JW929]

Will do!

Well, is this the same genny that you had low hertz on? And you opened the throttle skrew to get hz up?

 

[JW929]

Yes, the very same one. You think that me opening the throttle screw had something to do with it? I fired it up at least 6-8 times and shut it down without any problems.

Probably not but something else my be hinky with throttle control, i would get it primed back up, and recreate problem. Was emergency shut off bypssed during testing?

I am out of time tonight, Guy will assist also after he gets his coffee here in a bit

 

[JW929]

Emergency bypass? No clue where that is. Is that the dead crank toggle? If so, she tried turning that to off as well and it ran for a solid day and half or so before it ran out of fuel.

Big red button on control panel, says emergency shut down

 

[JW929]

Oh yeah, I had her FaceTime me and I saw that. I had her push it in and pull it out and nothing happened.

 

[JW929]

Well I fired it up again and it still won’t turn off. The emergency shut off button does not work either. It doesn’t appear that there is a fuel shut off valve. Any suggestions other then letting it run out of fuel?

Manually operate the throttle, loosen jam nut, same as increasing throttle just on other side

Disconnect 2 wires from governors control on top on injection pump

The fuel shut off is the governor control box on the top of the injection pump. Did you adjust any of the rheostats on govern control behind control panel?

[JW929]

No I have not adjusted anything since I haven’t a clue what I should be adjusting. I will see if I can locate the two wires on the injection pump. Any insight as to what I should adjust would be greatly appreciated.

Pull wires first at injection pump. If it doesn’t shut down, loosen fuel line at injection pump

 

[JW929]

I disconnected the plug going to the actuator and it’s still running.

Loosen throttle the other set skrew, and push lever the other way
