    Hi All,
    My new to me QSC engines do not have a WIF sensor installed, do I buy the blanking cap or the sensor.
    Is the sensor worthwhile?
    Thanks Luke

    Where did you get the terminating resistors from? Can you send us a picture of the harnessing / wiring?

    Hi Guys,
    So I still have on going alarm issues. Both engines have WIF alarms every time, both have a terminating resistor. Yesterday I scrubbed both the ecu plugs with wd40, pinged the cable and I have the same resistance on the ECU plug so the wires are good . I have tried de-powering the ECU overnight. Cummins has plugged in and they see the alarm on the ECU. Is there any other place to look? Could the ecu have a fault?

    While the alarm is not overly important it is just annoying.

    Thanks Luke

    Thanks Everyone,
    Yes I have the alarm, and understand I need the termination or the sensor. How great is the sensor to have?
    I have never had water in the fuel in 10 year and around 100 hrs a year I have a racor 1000 with a 10 micron
    and am dropping to 2mic on the next change.

    It was a repower from 2 x 3208 cats to 2 x 540 qsc’s . As soon as it is tidy I will post some pics. V 1 smart craft
    I having fuel and ecm issues but I will ask that question soon once I argue with Cummins about 12-24 recals some more.

    WIF circuit

    On a WIF circuit you either must have a working sensor OR a terminating resistor to “fake” the circuit and prevent any fault codes.

    You have to have “something” in the system or you would have a error code on the display..

    New boat?

    Old boat that you just bought?

    Repower?

    Formal “sea trial” ?

    Type of instruments?

    Post the engine serial number(s)

    I’d like to see good pictures of the installation..

    Yes, you need to have a WIF sensor installed and properly configured. What filtration is installed? and what Smartcraft system?
