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
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 Figures 4-53 and 4-54.
1. Park the mower safely. (See “Park Mower Safely” on
page 1-6.)
Figure 4-53
2. Disconnect the fuel shutoff solenoid wire connector
(1).
Figure 4-54
3. Set the meter to read ohms.
4. Measure the resistance between terminal (4) and
ground (2).
Is the resistance value approximately 15 ohms?
YES Proceed to step 5.
NO The fuel shutoff solenoid is faulty; replace
the solenoid.
5. Measure the resistance between terminal (3) and
ground (2).
Is the resistance value approximately 0.5 ohm?
YES The fuel shutoff solenoid is good.
NO The fuel shutoff solenoid is faulty; replace
the solenoid.
