- Question Title: Ingersoll Rand sand blaster won't shut off

I have a Ingersoll Rand 185 diesel, tow-behind compressor that I use for media blasting. The unit runs great, makes air pressure/volume as it should and has been a great little unit.
Yesterday, the battery was a bit low so I placed a charger on it, after 20 minutes or so, I turned the engine over to check the battery. The engine started fine but was low on fuel, so I turned the key off to shut the machine down... with no effect.
After turning the key to the "on" and "off" positions several times, the engine went to a low rough idle, but would not shut down. replaced the "ignition switch" with a new one and still, the engine continued to run, had to let it run out of fuel... HELP
These two pics are the only ones of the unit I have on hand. It has a John Deere diesel engine, and is a 2004 model.

Hello Nathan,
There is, as you found out, only one way to stop a diesel engine: cut off the fuel supply.
For this reason, these diesel driven compressors (any make/model) have a device that shuts off the fuel when you switch the unit off.
This device is called the full shut-off valve or solenoid, or stop solenoid.
Sometimes it is a separate device, sometimes it is a solenoid that connects to the engines fuel pump.
A solenoid is an electrically operated valve, it simply opens and closes when you put power on it.
Either way, it shuts off the fuel supply to the diesel engine, or it puts the fuel pump on zero output.
In your case, it seems like this stop solenoid has died or at least doesn't function properly anymore. Maybe it was burned by the higher voltage of the battery charger, I don't know.
It seems like it's now stuck on 'a little bit open', so the engine will run, but with not enough fuel.
So, find this fuel stop valve/solenoid on your compressor and see if you can clean it, or replace it.
It is most probably a John Deere part that sits on the diesel engine near the fuel pump.
Good luck and let me know if you need any more help.
