🔧 Product Description

Genuine Volvo Penta wiring harness for the alternator, weighing 1.055 kg and listed for 16 applications on D series engines. It supersedes part number 3817049. Note that the resistor 3889282 is also listed against 3817049, so an order placed on that old number alone needs checking against the parts list to see which of the two you actually want.

⚙️ Key Features

  • For the alternator
  • 1.055 kg
  • Supersedes 3817049
  • 16 applications on D series engines

🔌 Function

Carries charging current and the alternator's control and warning signals between the alternator and the engine electrics.

⚠️ Common Signs of Failure

  • Charge warning coming and going, or no charge at all
  • Terminals or connectors discoloured, blued or melted by heat
  • Green or white corrosion in the alternator connector
  • Insulation chafed through where the loom passes the engine or a bracket
  • Voltage at the battery well below the alternator's output

🛠️ Service Notes

  • The old number 3817049 is claimed by both this harness and the resistor 3889282, so check your parts list rather than ordering on the superseded number
  • Isolate the battery before working on charging cables, as they are live even with the engine stopped
  • Clean the alternator and engine earth connections at the same time, since voltage drop there is often blamed on the loom
