Fuel Shutoff Solenoid Test
See Figure 4-43.
1. Park the mower safely. (See “Park Mower Safely” on
page 1-7.)
2. Identify and locate the fuel shutoff solenoid and its
connector on the engine block near the air cleaner.
3. Disconnect fuel shutoff solenoid electrical connector.
Figure 4-43
4. Measure resistance between terminal (1) and ground
(2) (solenoid mounting bolt).
Does the resistance through the solenoid read
approximately 15.58 ohms?
YES Proceed to step 5.
NO The solenoid is faulty; replace the solenoid.
5. Measure ohms resistance between terminal (3) and
ground (2) (solenoid mounting bolt).
Does the resistance through the solenoid read
approximately 0.375 ohms?
YES The solenoid is good.
NO The solenoid is faulty; replace the solenoid.
Backlap Switch Test
See Figure 4-44.
1. Park the mower safely. (See “Park Mower Safely” on
page 1-7.)
2. Identify and locate the switch and its connector
beneath the operator's platform using electrical
component location diagram.
Figure 4-44
3. Disconnect the backlap switch electrical connector.
4. Remove two bolts holding switch to frame and
remove the switch. Inspect switch for damage.
5. Using a multimeter set to test continuity or a
continuity tester, measure the continuity between
terminals (1 and 2) while operating the switch.
Is continuity indicated?
YES The switch is good.
NO The backlap switch is faulty; replace the
switch. (See “Backlap Switch” on page 4-86.)
