Raise/Lower Switch Assembly Test
See Figure 4-24.
1. Park the mower safely. (See “Park Mower Safely” on
page 1-6.)
2. Remove raise/lower switch assembly. (See
“Raise/Lower Switch Assembly” on page 4-55.)
3. Set the meter to read ohms.
4. Touch meter leads to each other and confirm a
resistance value of 0.0 ohms.
Figure 4-24
5. Measure the resistance between terminals (2 and 3).
Is the resistance value 0.02 ohm or less?
YES The switch is faulty; replace the 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 ohm or less?
YES Proceed to step 7.
NO The switch is faulty; replace the 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 ohm or less?
YES The switch is faulty; replace the 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 ohm or less?
YES The raise/lower switch assembly is good.
NO The raise/lower switch assembly is faulty;
replace the raise/lower switch assembly.
