Radiator Fan Switch Inspection

• Remove the left lower fairing (see Lower Fairing Removal in the Frame chapter).

• Remove the fan switch (see Radiator Fan Switch Re­moval in the Cooling System chapter).

• 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 [C] are located in almost the same depth.

NOTE

OThe switch and thermometer must not touch the con­tainer sides or bottom.

• Place the container over a source of heat and gradually raise the temperature of the water while stirring the water gently.

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

• If the hand tester does not show the specified values, re­place the switch.

Radiator Fan Switch Resistance Rising temperature:

From OFF to ON at 96 ~ 100°C (205 ~ 212°F)

Falling temperature:

From ON to OFF at 91°C (196°F)

Less than temperature at ON ON: Less than 0.5 Q OFF: More than 1 МП
