During an oil change I noticed the tach sending unit located on the accessory housing on my O-320 was a little loose. I tightened it down. The tach was reading for another 2 flights and then stopped displaying on my Dynon EMS-D10.
I removed the tach (transducer?) from the back of the engine to see if the input shaft was sitting correctly and as far as i can tell it all connected the way it logically seemed it should. I spun the prop while putting my finger on the output from the engine and i could feel that it was turning. I hear what seems to be some rattling when i shake the transducer but since I've no experience with this type of device I am not sure if that is acceptable.
1. does anyone have any experience with this?
2. it seems like an easy enough part to replace. any thoughts of what its actually called and who might have this or a comparable replacement unit?
Thanks in advance for your help.
The unit highlighted in Yellow.
The nut that backed out is in Red.
The part number from the back of the device.
The wires going into the harness. All are solid connections.
