Fuel Receiver Gauge Malfunction: Description

• The combination meter assembly uses the fuel sender gauge assembly to determine the level of the fuel in the fuel tank. The resistance of the fuel sender gauge will vary between approximately 13 Ω with the float at the full position, and 415 Ω with the float at the empty position. The meter outputs battery voltage through two resistors of 820 Ω that are mounted in parallel inside the combination meter assembly. The combination meter assembly measures the voltage between the variable resistor in the fuel sender gauge and the two resistors mounted in parallel in the combination meter assembly. Voltage measured at this point will vary as the float of the fuel sender gauge is moved. The highest voltage observed should be approximately half of the auxiliary battery voltage.

HINT: 

The fuel level gauge and fuel level indicator will blinks when the fuel level is below 6.0 liters (6.3 US qts, 5.3 Imp. qts).
