Having trouble with the engine/rotor rpm gauge in cab. it lights up and only shows zeros. I replaced it with another monitor from a salvage combine but it does the same thing. wiring problem or sending problem. any suggestions to trouble shoot problem

Are you sure the rotor two speed gear box is in gear and not neutral?

What about the sensor on the front of the rotor is it adjusted right or working?

How do you test the sensor? the rotor is in drive.
