  Check the twilight sensor signal by varying the light intensity at the twilight sensor. Cover the twilight sensor with your hand to reduce the signal. Then aim a strong light source (for example a flashlight) at the twilight sensor from close range to obtain the maximum signal.

  The value should vary between approximately 0.5 and 4.75 volts.
