Kawasaki KLX 250 Coolant Temperature Warning Circuit. When the ignition switch is turned on with the transmission in neutral, the warning light flashes regardless of coolant temperature. This is to show if the light bulb has burned out. If the water temperature is high, the warning light flashes even if the transmission is in gears until water temperature falls. If the system does not function properly, inspect it as follows. The following schematic illustrates the Kawasaki KLX 250 Coolant Temperature Warning Circuit Diagram.
