    2005 226 Intermittently loses all Faria gauges

    Ok, I've been troubleshooting this issue on my 2005 Nautique 226 TE or over 3 years now and am running out of ideas and $$$.. If your idea can help me solve it I will send a Amazon gift card your way!


    Problem Description
    All gauges will be working great when cruising along and then all of a sudden I lose all my gauges. It's like power was just cut from them, gauge backlights turn off, all readings go to zero, etc. They reset, and will start working again like nothing happened. If the gauges are working I can just have the ignition on without running the boat and I don't see any gauge issues. Sometimes the gauges don't initiate when I turn on the ignition and then once I start the motor and get it up to speed they start working. When this issue started it would just happen every once-in-a-while but now it is happening more often. PLEASE HELP...


    What I've Done so far
    - Reset all connections on the Faria Gateway box that sits back behind the motor
    - Replaced the Faria Gateway box at $600 (I've got an extra one now if someone needs it)
    - Purchased a new PME (Bad Dash Pod Circuit Breaker Box) from NautiqueParts.com (another $800) thinking it could be the issue as the power supply connections to the Faria gateway box come from the PME (I've got an extra one now if someone needs it)
    - Unplugged the connection to the first Faria gauge and plugged it into the second gauge thinking it might just be an issue with the first gauge, all gauges stopped working until I undid this and got the boat up to speed for 30-60 seconds when all gauges started working again...
    - I have taken it into my local Nautique boat shop but they weren't able to help me (it didn't happen for them when they had it)


    What I've noticed
    - It seems to happen only when running the boat, at idle or before the boat has started I haven't yet seen the issue happen
    - Nothing else in the boat has intermittent loss of power (e.g. Stereo, Ballast Gauges, Horn, ZeroOff)


    What to do now???


    I've attached some reference material showing wiring from PME and Faria Gateway box.IS0151_C_Serial_Bus_for_correctCraft.pdfGATEWAY HARNESS Layout1.pdf
