Water Temperature Warning System Inspection

The water temperature warning light goes on when the ignition switch is turned on and goes off soon after the en­gine starts running (oil pressure switch off) to ensure that its circuit functions properly. The warning light also goes on whenever the coolant temperature rises to 113 ~ 117°C (235 ~ 243°F) when the motorcycles is in operation. If it stays on, stop the engine and check the coolant level in the reserve tank after the engine cools down.

• Inspect the water temperature warning light and the sys­tem wiring (see Wiring Inspection).

• Turn on the ignition switch.

• Disconnect the water temperature switch lead [A] and oil pressure switch lead, then ground them together to the frame or engine using auxiliary lead.

• If the warning light is lit, inspect the water temperature switch (see Specifications) and the oil pressure switch [B]. Replace any switch if damaged.

• If the warning light is not lit, check the warning light bulb.
