## 🔌 Function

Carries power and signals between the drive's electrical items on one pre-formed loom, with the connectors and routing already set.

## ⚠️ Common Signs of Failure

-   Intermittent operation of anything the loom feeds
-   Green corrosion inside a connector or wicking up under the insulation
-   Chafe through the outer sheath where the loom crosses a bracket
-   Broken conductor inside intact insulation, found only by flexing
-   Melted or hardened sheath near a hot surface

## 🛠️ Service Notes

-   Harness 3857346 in the same group weighs 0.834 kg, so if a loom is being matched by eye, check the connector count and routing rather than assuming
-   Copy the original routing, clips and grommets exactly, since most harness failures are chafe at a fixing point
-   Isolate the battery before disconnecting anything
