2. Remove the instrument panel to gain access to the back of the fuel gauge/hour meter.
See Key Switch
Removal, Section 13, Page 13-14.
3. Place a sheet of insulating material between the front frame and the electrical connections on the rear
of the instrument panel to prevent contact between the two.
4. Disconnect the orange wire from the fuel gauge/hour meter.
5. Set a multimeter to 20 volts DC and place the red (+) probe of the multimeter on the positive post of the
battery. Place the black (–) probe on the negative post of the battery. Record the voltage reading.
6. Set a multimeter to 20 volts DC and place the red (+) probe of the multimeter on the (2) terminal of the
fuel gauge/hour meter with the blue wire. Place the black (–) probe on the (3) terminal of the fuel gauge/
hour meter with the black wire
(Figure 11-37, Page 11-34)
.
7. Connect the battery cables, positive (+) cable first, and tighten to 144 in-lb (16.3 N·m).
8. Turn the key switch ON. The voltage reading should be the same as the battery voltage reading recorded
earlier. If not, check the continuity of the blue and black wires
(Figure 11-37, Page 11-34)
.
9. The orange wire should remain disconnected for this step. With the black probe still on the (3) terminal
of the fuel gauge/hour meter, place the red (+) probe of the multimeter on the (1) terminal of the fuel
gauge/hour meter
(Figure 11-38, Page 11-34)
. The voltage reading should be approximately 1.81 volts.
If the reading is incorrect, replace fuel gauge/hour meter.
Test Procedure 26B – Fuel Gauge (From mid-2007)
1. Turn the key switch OFF and remove the key. Place the Forward/Reverse handle in the NEUTRAL posi-
tion. Chock the wheels.
2. Remove the instrument panel to gain access to the back of the fuel gauge/hour meter.
See Key Switch
Removal, Section 13, Page 13-14.
3. Place a sheet of insulating material between the front frame and the electrical connections on the rear
of the instrument panel to prevent contact between the two.
4. Disconnect the orange wire from the fuel gauge/hour meter.
5. Set a multimeter to 20 volts DC and place the red (+) probe of the multimeter on the positive post of the
battery. Place the black (–) probe on the negative post of the battery. Record the voltage reading.
