Full model list at the end of this description.

## ⚙️ Key Features

-   Alternator cable for 24 V systems
-   0.071 kg
-   Listed for 43 D series engine applications
-   Terminal condition matters at both ends because it carries charging current

## 🔌 Function

Carries charging current from the alternator into the 24 V system, so the batteries are replenished while the engine runs.

## ⚠️ Common Signs of Failure

-   Batteries not charging or charging poorly with the engine running
-   Charge warning lamp lit or flickering
-   Terminals hot, discoloured or showing melted insulation
-   Green or white corrosion at the connections
-   Insulation chafed through where the cable is clipped or passes an edge

## 🛠️ Service Notes

-   Confirm the system voltage before ordering - a 24 V cable is not interchangeable with a 12 V one
-   Clean both terminals to bright metal and tighten to the specified torque; a poor joint here makes heat rather than charge
-   Check the cable routing and any chafe points while it is off
