## ⚠️ Common Signs of Failure

-   Gauge remains at zero
-   Erratic speed reading
-   Fogging or moisture inside the lens
-   Failed backlighting
-   Communication or sensor fault

## 🛠️ Service Notes

-   Isolate the battery before disturbing instrument wiring, and note the existing connections as they come off so the gauge goes back the same way
-   Check the sender and its plumbing or wiring before condemning the gauge — most dead or wrong readings come from a fouled or damaged sender, a blocked tube, or corroded connections rather than the instrument
-   Clean the terminals, make the connections up tight, and refit the sealing boots, grommets and gaskets so the panel stays watertight from both front and back
-   Set the instrument up as the instructions for your installation describe, then check the reading against a known reference on the water before calling the job done
-   Keep the gauge properly clamped in a sealed aperture; a loose instrument works its own connections apart and lets water in behind the panel
