## ⚠️ Common Signs of Failure

-   Intermittent operation of the circuit that worsens with vibration or damp weather
-   Housing cracked, distorted by heat, or its latch broken so it no longer clips shut
-   Green or white corrosion on the contacts inside once opened
-   Seal or grommet perished, with water tracking into the housing

## 🛠️ Service Notes

-   Neither a usable weight nor a fitment list is published for this number, so confirm it against the engine's own wiring parts list for your engine before ordering
-   Renew the seal or grommet with the housing, since water ingress is the usual reason the housing is being replaced
