I have had a bad oil pressure sender. Its seal was blown and the contact was
coated with a thin film of oil. This shorted the sender hence the low oil
alarm would sound. After cleaning the contact the alarm stopped. Replacing
the sender was an easy solution.

The oil pressure alarm remains on, and no oil flows out if the oil
pressure warning switch is removed.
