(12) Coolant Temperature Sensor
Coolant Temperature Sensor
1) Connector Voltage
1. Disconnect the 1P connector from the thermo switch (1).
2. Turn the main switch key to the "ON" position, and measure the
voltage with a voltmeter between the connector terminal and the
chassis.
3. If a certain voltage is not indicated, the wiring harness is faulty.
2) Thermo Switch Continuity
1. Disconnect the 1P connector, and remove the thermo switch.
2. Using an ohmmeter, check for continuity between the switch
terminal and the chassis.
3. If infinity is indicated at temperature over factory specifications,
the switch is faulty.

Grass Container Full Switch Continuity
1. Remove the battery.
2. Dismount the grass container.
3. Remove the filter cover.
4. Disconnect the connector (1) from the grass container full switch
(2).
5. Measure the resistance with an ohmmeter between the grass
container full switch terminals.
6. If the grass container full switch is defective, replace it.
