<p>A water detector apparatus (20) for detecting water in the various reservoirs of a fuel system. The water detector apparatus (20) includes a support housing (22) for supporting control electronics. Electrically interconnected to the electronics by an electrical lead (24) is an electrically conductable probe (26) which is at least partially threaded into the interior of a reservoir (28) of the fuel system. An oscillator (58) is included as part of the electronics for providing the electrically conductive probe (26) with an AC signal. The electronics further includes circuitry for comparing the resultant resistance of the electrically conductive probe (26) with a known resistance and further providing an output signal representative of the resultant resistance of the electrically conductive probe (26). A green LED (36) is electrically interconnected to the output so as to be lit when a low output is provided, indicating the absence of water and a red LED (38) is electrically interconnected to the output to intermittently blink when a high output is detected, indicating the presence of water.</p> |
