TASK INSTRUCTIONS:
1. While looking at fuel gauge, turn master switch on, pause for a moment, then off. The red LED in
the fuel level gauge should illuminate momentarily after the switch is turned off. Several cycles
may be needed to be sure of the result. If the LED is not seen, the gauge could be faulty or the
low-level switch may have become disconnected or damaged.
2. Verify that the surface of the fuel in the tank is below the low-level sensor (<2 gallons).
3. Check that signal power is getting to gauge:
a. Unplug the connector at the fuel gauge.
b. Turn master switch on. The voltage between Pin 1 and Pin 3 at the aircraft harness gauge
connector should be 12v. If it is not, the sensor may be faulty.
c. Turn master switch off.
