Are you checking it after warmup and drain down? Any chance it is a fuse or wire issue? How long was the interval between the previous oil change. That is an oil pressure light, not an oil volume, it could be reading wrong, or you could have gunked up some passages. But I would think its something simpler, like the sending unit or a loose wire. Check cheap and easy first. Do you have a manual. You need to confirm if the sending unit is working first, (after checking oil).

+1 and you need a manual, there are test procedures in there for the pressure sensor. Do not run your engine any more with that light on, It may be something simple, and it may not.

 

I checked it when it was warm after the ride.
Definitely plenty of oil in it.
Will check all wires when I get a chance.
My initial thought is that it is the sender unit.
Anyone ever change one of these before?

 

Idiot Light is for oil pressure not oil level.... It is a reference for oil level and can signal for too low and too high a level. But real purpose is pressure.
