## ⚠️ Common Signs of Failure

-   No throttle or speed response
-   Engine speed hunting
-   Failure to reach governed speed
-   Actuator stationary despite a valid command
-   Excessive actuator vibration
-   Governor or actuator fault
-   Overheated actuator or wiring
-   Engine stopping when electrical control is lost

## 🛠️ Service Notes

-   Note the fitted position and any linkage settings before removal, so the new unit can be set up the same way
-   Isolate the batteries, and relieve any pressure in the system, before disconnecting an actuator
-   Check the linkage, pivots and mountings move freely; a stiff or seized mechanism will kill a new actuator as surely as it killed the old one
-   Fit it so it works through its full travel without binding and reaches both end positions properly, with the connector seated dry and locked
-   Some actuators need calibration or a learning procedure with Volvo Penta diagnostic equipment before they will operate correctly, so check what your engine requires
