Sullair 185 getting 3 flashes from the SSAM

Have a 2005 Sullair 185 compressor. John Deere turbo diesel engine. Getting 3 flashes from the SSAM. Replaced engine oil and filter. Still gets 3 flashes and shuts down. Getting 55psi of oil pressure, verified with mechanical gauge. Will only stay running if you ground the wire that hooks to the sensor/switch. Have replaced the sensor/switch with one matched up from Napa auto parts. Still shutting down and showing 3 flashes. I need the correct PN for the oil pressure sensor/switch.
