-   Sound weak, distorted or intermittent
-   Horn sounding continuously with no fault present
-   Terminals corroded or the connection green
-   Body cracked or water inside the unit

## 🛠️ Service Notes

-   This is part of the engine's audible warning system, so test it works after fitting rather than assuming it does
