Yes, as Capt. Perry said, the problem is probably the one alarm that is not sounding when you shut down, not the one that is. It is very likely a grounding issue. Also, not always, but most often, most oil pressure senders are one wire (ground return) and most oil pressure switches are two wire (with 2 or 3 contacts).
