## 🔧 Product Description

## 🔌 Function

Makes and breaks the starting circuit at the helm, energising the starter when the key or button is operated.

## ⚠️ Common Signs of Failure

-   Starter engages only intermittently, or needs the key held over
-   Nothing at all at the helm with a good battery and good earths
-   Switch action gritty, sticking, or slow to return
-   Terminals corroded or showing heat marks
-   Starter continues to crank after the key is released

## 🛠️ Service Notes

-   Rule out the battery, main earth and starter feed first - they mimic a failed switch closely
-   Isolate the battery before removing the switch; the feed side stays live with the key out
-   Starter switch 856659 is the EVC-MC part and covers different engines; order by part number
