I have Dynon EMS DEK180 on a 912ULS - Oil pressure does not go to zero when the engine is turned off. I took off the cowl to inspect and when I turned on the Dynon - it was reading zero. I looked everything over, turned the prop a bunch of times saw the pressure go up and back to zero. I put the cowl on and a week later - turn on the Dynon and see 47PSI again. Would appreciate any ideas of what to do next. I have the Honeywell oil pressure sender.
