🚤 Compatibility

Typically suits:

  • Volvo Penta D4-260I-A
  • Volvo Penta D4-260I-B
  • Volvo Penta D4-300I-A
  • Volvo Penta D4-210A-A

  • Engine Family: D
  • HP Range: 180-300 HP

⚙️ Key Features

  • Sealed application-specific connectors
  • Branch lengths follow the original engine routing
  • Conductor sizes match circuit load
  • Integrated shielding or twisted pairs where required
  • Harness generation, ECU dataset and engine serial number must match
  • Engine type: D13 electronically controlled marine diesel electrical system

🔌 Function

Connects the ECU, sensors, actuators and installation interfaces while protecting low-voltage signals from heat, oil, moisture and vibration.

⚠️ Common Signs of Failure

  • Multiple unrelated fault codes appearing together
  • Power or communication dropping out when the loom is moved by hand
  • Heat damage or hardened insulation on a branch near the exhaust
  • Water in a connector, with corroded or discoloured pins
  • Chafed-through conductor shorting to the engine block, found on strip-down

🛠️ Service Notes

  • Trace and repair the cause of any chafe before fitting a replacement, or the new harness will fail in the same place
  • Check the supply and ground terminations, as voltage drop there mimics a failed harness
