(i) Turn BAT switch to the ON position.
(j) Adjust both the left and right full adjustment screws until the needles indicate full.
(k) Turn BAT switch to the OFF position.
(l) Install the fuel indicator adjustment screw covers.
(m) Install right mid-console trim. (Refer to 25-10)
(4) Test - Fuel Quantity Indicator and Fuel Sender Test
(a) Verify the ignition switch is in the OFF position and remove the key.
(b) Place the BAT Master Switch in the OFF position.
(c) Fill each fuel tank with 41 gallons of fuel. (Refer to 12-10)
(d) Remove right mid-console trim panel. (Refer to 25-10)
(e) Locate and unplug wire harness from the fuel level indicator.
(f) Place multimeter in the 100-ohm scale and zero out the ohmmeter.
CAUTION: If battery power is on for the following test, the ohmmeter could become
permanently damaged.
(g) Connect black (-) ohmmeter lead to pin # 9 (blue, ground) fuel sender wire. Connect the
red (+) positive ohmmeter lead to pin # 2 (white, power) fuel sender wire. The meter
should read 69 to 77 ohms resistance when the left tank is full.
Note: If the left tank were empty (dry), the meter should indicate 1 to 5 ohms
resistance. If these specifications are not met, inspect the fuel sender itself
or the wires and connectors to the sender. If the left tank had unusable fuel
(1-1/2 gallons) remaining inside of the tank, the meter should indicate 4.4 to
12.4 ohms resistance.
(h) Connect black (-) ohmmeter lead to pin # 9 (blue, ground) fuel sender wire. Connect the
red (+) positive ohmmeter lead to pin # 4 (orange, power) fuel sender wire. The meter
should read 69 to 77 ohms resistance when the right tank is full.
Note: If the right tank were empty, the meter should indicate 1 to 5 ohms of resis-
tance. If these specifications are not met, inspect the fuel sender itself or
the wires and connectors to the sender.
(i) Connect the fuel level indicator wire harness to the fuel sender wire harness.
(j) Set multimeter to the DC 30-volt scale.
(k) Turn the key switch (main power supply) to the ON position.
(l) Connect the red (+) voltmeter lead to fuel indicator pin # 1 (power), connect the black (-)
voltmeter lead to fuel indicator pin # 9 (ground). Battery voltage should be present.
Note: If battery voltage is not present, inspect circuit breakers, wiring harness,
voltmeter, and battery. If the fuel sender resistance checks good and there
is battery voltage to the indicator, the indicator or wires and connector to the
indicator are faulty.
(m) Install right mid-console trim panel. (Refer to 25-10)
