Brake• Light Timing Inspection

Refer to the Brakes in the Periodic Maintenance chapter.

Brake• Light Timing Adjustment

Refer to the Brakes in the Periodic Maintenance chapter.

Switch• Inspection

Using a hand tester, check to see that only the connections shown in the table have continuity (about zero ohms).

○For the handlebar switches and the ignition switch, refer to the tables in the Wiring Diagram.

If the switch has an open or short, repair it or replace it with a new one.

ELECTRICAL SYSTEM 16-75

Switches and Sensors

•Remove the fan switch [A].

•Suspend the switch [A] in a container of coolant so that the temperature–sensing projection and threaded portion

•are submerged.

Suspend an accurate thermometer [B] in the coolant so that the sensitive portions are located in almost the same depth.

NOTE

○The switch and thermometer must not touch the con-

•Place the container over a source of heat and gradually raise the temperature of the coolant while stirring the

•coolant gently.

Using the hand tester, measure the internal resistance of the switch across the terminals at the temperatures shown in the table.

Special Tool - Hand Tester: 57001–1394

If the hand tester does not show the specified values, re- place the switch.tainer sides or bottom.

Fan Switch Resistance Rising temperature:

From OFF to ON at 93 103°C (199 217°F)

Falling temperature:

Fan stops with the temperature 3 8°C (38 46°F) lower than the operation temperature range.

ON: Less than 0.5 Ω OFF: More than 10 MΩ

Water• Temperature Sensor Inspection

•Remove the fuel tank (see Fuel System (DFI) chapter).

•Disconnect the water temperature sensor connector [A]. Remove the water temperature sensor [B] (see Fuel System (DFI) chapter).
