## 🔌 Function

Opens the circuit if current exceeds its rating, protecting the charging or supply wiring from an overload or short.

## ⚠️ Common Signs of Failure

-   Charging or supply circuit completely dead
-   Fuse element visibly parted or the body discoloured
-   Repeat blowing shortly after replacement, pointing to a fault upstream
-   Heat marks or melted plastic around the holder
-   Intermittent operation as a corroded fuse end loses contact

## 🛠️ Service Notes

-   Never fit a higher rating than 50A to stop it blowing, as the fuse protects the cable and not the fuse itself
-   A fuse that blows again immediately means the fault is still there, so trace the circuit before fitting a third one
-   Clean the holder contacts and check they still grip firmly
