LEAK DETECTOR CIRCUIT
Components can be tested by isolating them from the
rest of the circuit and individually testing the suspected
component.
Delay Timer
This is a solid state device with no moving parts. Upon
the application of power, the time delay is initiated. At the
completion of the 1 second delay, the audio alarm be-
comes energized. When power is removed the timer is
reset.
1. Isolate timer from the circuit. Connect 12VDC
source in series with voltmeter to connector of timer.
Make sure to observe polarity.
2. The voltmeter should jump from 0 to 12VDC after
the 1 second delay. Remove voltage source from the
timer. Reconnect timer to the circuit.
Audio Alarm
1. Isolate alarm from the circuit. Connect 12VDC
source to terminals. Make sure to observe polarity.
2. Alarm should sound. Remove voltage source from
the alarm. Reconnect alarm to the circuit.
