I'm not sure about those engines specifically, but I think that in general the horn goes off for:

-low drive gear oil in the reservoir
-low oil pressure
-high water temperature

All Guages Look Good,nothing Abnormal At All ,thats Whats Throwing Me Off

Check your impellers.

Since the gauges look good, double check the fluid level in your drive bottles.

Isolate the warning system one at a time. As US1 said, check the drive resevoir 1st.

I always thought there wer 4 things
but am drawing a blank of what hte fourth is from what is already listed

fuel pressure?

Low voltage also sets them off.

At 10 volts, maybe not enough juice goes to the other previously mentioned senders but it will go off. My alternator went and I was running on the batteries untill 10V and then it quit shortly after that. Must be no fuel pressure or the injectors won't open. (500 EFI)
