Seat Switch Test
See Figure 4-25.
1. Park the mower safely. (See “Park Mower Safely” on
page 1-6.)
2. Tag and disconnect the seat switch wire connectors.
3. Set the meter to read ohms.
4. Touch meter leads to each other and confirm a
resistance value of 0.0 ohms.
Figure 4-25
5. Measure the resistance between terminals (1 and 2).
Is the resistance value 0.02 ohm or less?
YES The seat switch is faulty; replace the seat
switch.
NO Proceed to step 6.
6. Depress the seat switch and measure the resistance
between terminals (1 and 2).
Is the resistance value 0.02 ohm or less?
YES The seat switch is good.
NO The seat switch is faulty; replace the seat
switch.
Raise/Lower Solenoid Test
See Figure 4-26.
1. Park the mower safely. (See “Park Mower Safely” on
page 1-6.)
2. Remove solenoid. (See “Lower Solenoid” on
page 4-61 or “Raise 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 4-26
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).
Refer to the specifications listed for the specific
solenoid resistance.
• Raise Solenoid Coil—
5.6 ohms ± 10% at 72° F (22° C)
• Lower Solenoid Coil—
5.6 ohms ± 10% at 72° F (22° C)
Does the resistance value match the specified
value listed?
YES The solenoid is good.
NO The solenoid is faulty; replace the solenoid.
