A month ago we made a 10 min. flight to buy gas.  On the way back about 5 min. out at 2500 ft. AGL we got a “Check Oil Pressure” annunciation.   It was about 70 psi from a normal 45 psi oil pressure when I looked.  The pressure was varying from 60 to over 90 but all other temps were normal and the engine seemed unaffected.   As my mind was racing through the options, that 5 minutes took a looong time to pass.  

 

My first call was to Electronics International to see if the MVP-50 Engine Monitor had any similar history.   David Campbell at EI told me the first place to check was the connectors.  It was the Molex (I know, I know) ahead of the firewall.  I had some Fastons (I know, I know) supplied by EI so they solved the problem for now.   The EI people have always been very helpful and do whatever it takes to address any issue I have had.
