I am reluctently posting this because it might help someone. I say relunctant
because it always seems soneone wants to contradict or nit pick you. But here goes anyway:
If you suspect a bad oil pressure sender and can't be certain if it is the sender or the Dynon D180, do this: Disconnect the wires from the sender and connect a resistor with one end grounded, and the other end to the wire that goes to pin #6 of the 37-pin plug into the Dynon. Here are some values you might use; a 22-ohm resistor produces a reading of 12-psi on the Dynon, a 50-ohm gives 25-psi, a 100-ohm gives 66-psi, and 150-ohm gives 100-psi (which I suspect is the highest the D180 would read in any case.)
I hope you never need this information, but I see another rv-12 flyer just posted an oil pressure failure.
FWIW
