The audible alarm produces a pulsating loud tone to
alert the operator of high engine temperature.
How It Works
Testing
There is +12VDC applied to the audio alarm when the
key is in the ON or RUN positions. The Water Temper-
ature Light provides a ground for the light and the audio
alarm.
Ground the negative terminal (-) on the alarm. Apply
12 volts to the positive terminal (+) on the alarm. If the
alarm does not sound, replace the alarm. If the alarm
does sound test the electrical circuit (Fig. 0822).
