It is the outside harness on the machine body — exposed to rain, wash-down, mud and UV. On most machines it is the section most often replaced.
| What the operator reports | Why the harness fits that symptom |
|---|---|
| Several circuits dead after rain or a wash | Water ingress at an outside connector. |
| Green corrosion at the plugs | The first visible sign; the strands behind the pin are usually worse. |
| Intermittent faults on rough ground | A loom that has lost its clips and is rubbing the frame. |
| One function fails, then another | Corrosion spreading through a shared connector. |
These are circuit-level symptoms, not a diagnosis. The same behaviour can come from a sensor, an ECM input or a mechanical fault — the checks below are how you tell them apart.
