⚙️ Key Features

• Wiring harness rated 28 V
• 0.059 kg
• Listed for 29 D series engine applications
• The 14 V harness 23030487 is the heavier of the two at 0.073 kg, so weight is no guide to voltage

🔌 Function

Carries power and signals through the 28 V side of the engine's electrical system, with the correct connector at each end.

⚠️ Common Signs of Failure

• A circuit that works intermittently and moves with vibration
• Green corrosion inside the connector bodies or on the pins
• Insulation melted or discoloured on a loaded circuit
• Insulation chafed where the loom passes a bracket
• Connector latch broken so the plug backs out

🛠️ Service Notes

• Confirm the system voltage before ordering - the 14 V harness 23030487 is a separate part and will not do
• Isolate the battery before disconnecting anything, and check the pins and earths before condemning the harness
