Does anyone know if you can check the RPM sensor for the shaft output with a multimeter and get continutiy. I am not getting the RPM. I have replaced the sensor now, have had the latest version of the firmware installed on the ECU. I have it plugged into EXP, have turned the plug around several times. I am trying to to do this in a method and rule out the sensor first. Makes me almost think that there is a setting in ECU to turn it on in the display of the GSU. No joy any help would be appreciated. It was originally working when brand new and then I had an incident, with the airplane and hasn't worked since. All I was getting was Prop Fail. At first it was restricting the core rpm to 50,000 which means an RPM sensor fail. Then replaced it and it let it spool up to full core rpm and still not a prop shaft display. Now again only a core spool up of 50,000. I know the magnet is in the prop hub. One would think the sensor would be gone again, but just after bench running? That's why I want to try and check the sensor.

Thanks
