## 🔌 Function

Turns engine rotation into electrical current, charging the batteries and carrying the vessel's electrical load while the engine runs.

## ⚠️ Common Signs of Failure

-   Batteries not charging, or a charge warning that stays lit
-   Charging voltage low, high or wandering at the panel

-   Bearing rumble, or a rotor that feels rough when turned by hand

## 🛠️ Service Notes

-   The number this replaces was listed as a remanufactured unit, so check what you are being quoted against before comparing prices
-   Check the belt, tension and both battery and earth connections before condemning an alternator - a poor earth gives the same symptoms
-   Confirm the 14V 115A rating suits your installation, as a different output rating is a different part
