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.
______________________________
Oil Pressure switch number
02250130-668 direct from Sullair as they install it after the motor leaves John Deere.

Did this part solve your problem?
I have replaced it with the John Deere part and still shuts down.
Please advise.
