🔌 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
