What is the Stop Engine dashboard warning light on a '94 8100? Mine comes on an off

The gauges all looked good, cruiser. But since this just happened suddenly, I'm not taking any chances.
I searched a few pages for other posts, now I'll do a more thorough search.

Thanks again , all. I'll try the codes tomorrow, if the weather conditions are not too bad.

 

Ok - the only sensor codes I could get were 3 red (stop engine light) then two red (stop engine light) I assume this to be a 32? No yellow lights. Getting information overload trying to figure out the meaning of this code, if it is a code.

 

So far : I've increased coolant level, checked rad. sensor and overflow coolant sensor. Will soon change coolant in-line filter, and look to clean and lube the injector harness. Still don't know about the flash code or Stop Engine light. All guages and fluids are good. Going to try to find a crankcase filter on this Detroit, and clean it. Will keep updating.....

 

Well, heavyd, I used to, but since this problem occurred, only the Stop Engine light (and the low air light,when necessary) come on. Then again, maybe I have a Warn Engine bulb failure as well. Round and round we go, wouldn't be so bad except the weather is atrocious and the truck is outside in it!
