Fuel Level Sensor Test
See Figure 4-51.
1. Park the mower safely. (See “Park Mower Safely” on
page 1-6.)
2. Remove fuel level sensor. (See “Fuel Level Sensor”
on page 4-111.)
Figure 4-51
NOTE
Float shown in the full position.
3. Set the meter to read ohms.
4. Connect test leads to sensor bracket (1) and sensor
terminal (3).
5. Move the float (2) to the full position and read the
resistance value.
Is the resistance value approximately 32 ohms?
YES Proceed to step 6.
NO The sensor is faulty; replace fuel level
sensor.
6. Move the float (2) to the empty position and read the
resistance value.
Is the resistance value approximately 256 ohms?
YES The sensor is good.
NO The sensor is faulty; replace fuel level
sensor.

1. Park the mower safely. (See “Park Mower Safely” on
page 1-6.)
NOTE
This procedure applies to the following solenoids:
• Front Mow Solenoid
• Right Mow Solenoid
• Left Mow Solenoid
• 4WD Solenoid
• 4WD Rev Solenoid
2. Remove solenoid. (See “Mow Solenoids” on
