How It Works

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.
Testing
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).
