What do those symbols mean?

Just curious. They are on the dash, but not documented. Probably not connected either.

I do, also. Is "O" for On or Off? "I" must mean "Imbecile".

When I first seen those "O" & "I" symbols, I was in a mandatory class of some sort at work.

I deducted that with the "O" being a continues loop like a 12 volt system, it must mean on. Thus reserving the "I" for shorted-out or off.

Boy, was I wrong!
