Low Fuel Alarm - Non Functional

I intentionally ran my left tank down to test the low fuel alarm. I got no warning, either audible or via the annunciator light. My ENGINE.AFD file contains the following, confirming that I should have received a warning below 2 gallons remaining:

TANK_1.MAX, 200
TANK_1.YELLOW_LOW, 40
TANK_1.RED_LOW, 20
TANK_1.UNITS, 0
TANK_1.ENABLE, 1
TANK_1.AUDIO, 1
TANK_2.MAX, 200
TANK_2.YELLOW_LOW, 40
TANK_2.RED_LOW, 20
TANK_2.UNITS, 0
TANK_2.ENABLE, 1
TANK_2.AUDIO, 1

Anybody know why this isn't working? It looks like I have the tanks enabled, and the audio enabled too.:confused:

How low was the tank?

Where you flying? the alarms only work when the prop is turning.

Was the fuel tank bar red?

Send me your system logs and the flight logs so we can check it.

Yes I was flying, the left tank indicated 0.4 gallons remaining when I switched tanks. I do not recall seeing a red indication on the fuel tank bar. I normally download the flight data logfiles postflight and will send you that now, the system log will have to wait until I go to the hangar again.

I just verified the alarms work on the test bench. There is a 30 second delay before the fuel tank alarms will trigger to avoid false alarms in steep turns. Try setting the yellow and red values to much larger values so you can safely verify the alarms operate during your next flight. Also, you should verify that the "Check Fuel Level" audio plays by going to the audio test page to rule out missing or currupted sound files.
