Fuel Gauge: Description and Operation
Fuel Level/Gauge
This system consists of a fuel level sensor and fuel gauge. The fuel gauge measures the quantity of fuel corresponding 63 liters (16.6 US gal) within
the range; full fuel tank (70 liters (18.5 US gal)) to remaining fuel 7 liters (1.8 US gal).
The sensor has a float. The position of the float (depending on the quantity of fuel) acts on the resistance in the circuit. When the float is in its upper
position, resistance is approx. 10 Ohms. This rises successively to approx. 325 Ohms when the float is in its lower position. A yellow warning lamp
lights when there are approx. 8 liters (2.1 US gal) of fuel left in the fuel tank.
When the fuel gauge is connected (with the ignition switched on) it should display the correct quantity of fuel within 3 seconds.
NOTE: When filling fuel with the ignition on or the engine running it takes a long time for the fuel gauge to reach the correct level because of the
built-in delay. The fuel gauge displays the correct level when the ignition is switched off and then on again.
The low fuel level warning lamp also lights when the generator (GEN) charging signal (D+) is low.
