Buzzers
Water Temperature Buzzer
The water temperature buzzer is a warning
buzzer connected to the ECU.
When a specified temperature is reached, the
ECU issues a signal, causing a buzzer to
sound (intermittent tone).
The specified temperature is 120 degrees
Celsius (120 °C).
With the circuit in this machine, the engine will
not stop even if the specified temperature is
exceeded.

When testing the water temperature buzzer,
disconnect the buzzer from the wiring of the
machine and test the buzzer as a single unit.
The water temperature buzzer is normal if it
emits an intermittent tone when the red wire is
connected to the positive terminal and the
black wire is connected to the negative
terminal of a 12 V battery.

specified quantity, there is continuity in the
level switch, causing a buzzer to sound
(continuous tone).
