See Figure 4-85.
NOTE
Test the component utilizing the LCD switch status menu
before performing the component bench test. (See
“Switch Test” on page 4-85.)

page 1-6.)
2. Remove raise/lower switch assembly. (See
“Raise/Lower Switch Assembly” on page 4-154.)
Figure 4-85
3. Set the meter to read ohms.
4. Touch meter leads to each other and confirm a
resistance value of 0.0 ohms.
5. Measure the resistance between terminals (2 and 3).
Is the resistance value 0.02 ohms or less?
YES Switch is faulty; replace raise/lower switch
assembly.
NO Proceed to step 6.
6. Move and hold the raise/lower switch assembly in
the lower position and measure the resistance
between terminals (2 and 3).
Is the resistance value 0.02 ohms or less?
YES Proceed to step 5.
NO Switch is faulty; replace raise/lower switch
assembly.
7. Return the raise/lower switch assembly to the center
(neutral) position.
8. Measure the resistance between terminals (4 and 5).
Is the resistance value 0.02 ohms or less?
YES Switch is faulty; replace raise/lower switch
assembly.
NO Proceed to step 9.
9. Move and hold the raise/lower switch assembly in the
raise position and measure the resistance between
terminals (4 and 5).
Is the resistance value 0.02 ohms or less?
YES Raise/lower switch assembly is good.
NO Raise/lower switch assembly is faulty;
replace raise/lower switch assembly.
Seat Switch Test
See Figures 4-86 and 4-87.
NOTE
Test the component utilizing the LCD switch status menu
before performing the component bench test. (See
“Switch Test” on page 4-85.)
1. Park the mower safely. (See “Park Mower Safely” on
page 1-6.)
2. Tag and disconnect the seat switch wire harness
connector. (See “Seat Switch” on page 7-10.)
3. Set the meter to read ohms.
4. Touch meter leads to each other and confirm a
resistance value of 0.0 ohms.
5. For the optional seat, proceed to step 8.
