NOTE
On some meters it will be necessary to select a range for
the solenoid being tested.
3. Using a multimeter or ohmmeter, measure the
resistance between terminals (1 and 2). Refer to the
specifications listed for the specific solenoid
resistance.
• Front Mow Solenoid Coil—7.1 ohms ± 10% at 68° F
• Right Mow Solenoid Coil—7.1 ohms ± 10% at 68° F
• Left Mow Solenoid Coil—7.1 ohms ± 10% at 68° F
• 4WD Solenoid Coil—8.8 ohms ± 10% at 68° F
• 4WD Rev Solenoid Coil—8.8 ohms ± 10% at 68 ° F
• Diff Lock Solenoid Coil—8.8 ohms ± 10% at 68° F
Does the resistance through the component
match the specified value listed?
YES The solenoid is good.
NO The solenoid is faulty; replace the solenoid.
Fuel Shutoff Solenoid Test
See Figure 4-54.
1. Park the mower safely.
Figure 4-54
2. Connect the black test lead to the fuel shutoff
solenoid black wire terminal (1).
3. Connect the red test lead to the fuel shutoff solenoid
white wire terminal (2).
4. Using a multimeter or ohmmeter, measure the
resistance between terminals (1 and 2).
Is the resistance value approximately 0.5 ohms?
YES Proceed to step 5
NO The fuel shutoff solenoid is faulty; replace
the solenoid.
5. Connect the red test lead to the fuel shutoff solenoid
red wire terminal (3).
6. Measure the resistance between terminals (1 and 3).
Is the resistance value approximately 15 ohms?
YES The fuel shutoff solenoid is good.
NO The fuel shutoff solenoid is faulty; replace
the solenoid.
