Mow Solenoid Test
See Figure 4-27.
1. Park the mower safely. (See “Park Mower Safely” on
page 1-6.)
2. Remove mow solenoid. (See “Mow Solenoid” on
page 4-62.)
3. Set the meter to read ohms.
4. Touch meter leads to each other and confirm a
resistance value of 0.0 ohms.
)
Figure 4-27
NOTE
On some meters it will be necessary to select a range for
the solenoid being tested.
5. Measure the resistance between terminals (1 and 2).
Is the resistance value approximately 9 ohms?
YES The solenoid is good.
NO The solenoid is faulty; replace the solenoid.
Fuel Shutoff Solenoid Test
See Figure 4-28.
1. Park the mower safely. (See “Park Mower Safely” on
page 1-6.)
2. Set the meter to read ohms.
3. Touch meter leads to each other and confirm a
resistance value of 0.0 ohms.
NOTE
Air intake removed for picture clarity.

4. Tag and disconnect the fuel shutoff solenoid wire
connector (1).
5. Measure the resistance between terminal (1) and
ground.
Is the resistance value approximately 1 ohm?
YES Fuel shutoff solenoid is good.
NO The fuel shutoff solenoid is faulty; replace
the fuel shutoff solenoid.
