    all gauges stopped working. Smart craft monitor shows all systems good but gauges on panel don’t move at all. Any help greatly appreciated

    You might need to do a master reset to factory settings. Hold troll + and troll - for 10 seconds or so. Check the manual to be sure.

    If you are getting the digital (gauge) readings on the SmartCraft then start looking at things common to the gauges themselves. Grounds would be first. They may have a common ground or loose plug that has lost connection for some reason. Use caution with factory resets, know the results (things you may lose) before doing it.

    This has happened to me and a few others here.

    If you can find this round connector, disconnect it and add some dielectric grease. It has helped resolve the issues for me.

    It’s located in the helm storage area on my 240 Sundeck, I’m not sure where you’d find it on your boat.

    Thanks...wasn't sure if there is a fuse leading to the gauge 12vdc. Bought the boat last year and there was a supply of fuses in a drawer :)
