## ⚙️ Key Features

-   20 A rating
-   0.02 kg
-   Listed for 53 applications on D series engines
-   The 7.5 A fuse 980555 and the 40 A fuse 979686 are the other ratings listed here

## 🔌 Function

Protects its circuit by melting and breaking the supply when current rises above 20 amps, before the wiring or the component it feeds is damaged.

## ⚠️ Common Signs of Failure

-   A circuit dead with no other symptom - instruments, pump or lamp simply stop working
-   Element visibly melted, or the body smoke-blackened inside
-   A replacement blowing straight away, which points to a short downstream
-   Blade or holder clip discoloured and the holder running warm
-   Fuse slack in its holder, giving an intermittent circuit

## 🛠️ Service Notes

-   Never fit a higher rating to stop it blowing - the fuse protects wiring sized for 20 A, and the next failure will be in the loom
-   A fuse that blows repeatedly is a symptom: find the short or overload before fitting another
-   Check the holder clips for spring tension and corrosion, as a slack clip runs hot and cooks the fuse
