-   Engine warning, reduced-power mode or shutdown
-   Open-circuit, short-circuit or correlation fault code
-   Intermittent response as the component warms

## 🛠️ Service Notes

-   Isolate the batteries before disconnecting anything, and label the leads as they come off so they go back on the correct terminals
-   Check the replacement matches the original for contact rating and action; a switch that cannot carry the load will burn its contacts
-   Clean the terminals, make the connections tight and dry, and support the loom so it is not left hanging on the switch body
-   Refit the seal, boot or gland that came with the switch — water getting in behind a switch is the usual reason they fail afloat
-   Work the switch through its full travel and confirm the circuit behaves correctly, including any interlock or alarm function, before the engine goes back into service
