Cause:
The fuel sender is not providing a valid indication of fuel
for the zero fuel level. To qualify for installation into a
certified aircraft the fuel sender must provide a valid

tank, do so now and return to the calibration
process.
2. The fuel sender system zero level is not
correctly set. Refer to the manufacturer
documentation and correct the problem.
3. The fuel sender system is defective. Replace it
with a new or rebuilt unit.
4. If the sender orientation is set in the
r
mode
check:
a. for an open circuit condition between the
instrument and the sender;
b. that the sender system output is not
shorted to ground.
