John Deere Ztrak 797 instriment lights

When I turn the key to the run position the lights on my instriment panel Ztrak 797 are supposed to light up and the buzzer should sound. THe low oil , high temp, and buzzer do not activate. These item do work if they are activate by the sensor with the engine running. Any suggestion on how to fix this problem?

Please advise,
