Low oil light is always on.

I changed the starter in my 87 420 the other day and now the low oil idiot light is always on. The oil level is at the proper mark.

How does the oil level sensor in these engines work. What is the basic detection mechanism?? I know the sensor is inside the crankcase so its a bear to get to.

Any ideas on what to look for?
