## ⚙️ Key Features

-   0.347 kg
-   87 applications across six engine series
-   Charging system control unit
-   Distinct from the 66-application unit 862539

## 🔌 Function

Holds the charging output at its set value as engine speed and electrical load change.

## ⚠️ Common Signs of Failure

-   Batteries persistently undercharged, or boiling and losing water from overcharge
-   System voltage swinging up and down instead of holding steady
-   Lamps brightening and dimming with engine speed
-   Charge warning lamp staying on with the engine running
-   Burnt smell or heat discoloration at the unit

## 🛠️ Service Notes

-   The other unit of this name in this run, 862539, covers a different 66-application list and weighs 0.017 kg; they are not interchangeable, so order against the application list
-   Check the belt, battery condition and the main charging connections before condemning the unit, since all three produce the same symptoms
