23397575 Wiring Harness | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta powertrain break-out wiring harness, weighing 0.042 kg and listed for one HPCU application. It shares its weight with the subnet break-out harness, so the circuit it serves is what identifies it.

🚤 Compatibility

Typically suits:

• Volvo Penta HPCU-B

• Engine Family: HPCU

⚙️ Key Features

• Powertrain break-out wiring harness
• 0.042 kg
• Listed for one HPCU application
• Same weight as subnet break-out harness 23397577, so the circuit named on the part is the only guide

🔌 Function

Breaks the powertrain network out of the main loom and takes it to the connector on the control unit, carrying the signals that the powertrain side of the system uses to talk to the rest of the installation.

⚠️ Common Signs of Failure

• Intermittent communication faults that come and go with engine vibration
• Warning lamp or fault code appearing at a particular throttle position or steering lock
• Outer sheath chafed through where the harness crosses a bracket or edge
• Pins pushed back, green or bent inside the connector shells
• Continuity present when static but breaking down when the loom is flexed by hand

🛠️ Service Notes

• Order strictly by part number - the powertrain and subnet break-outs weigh the same and look alike, and 23397577 is the subnet version
• Renew the harness rather than repairing a chafed section; a spliced joint in a network circuit is a recurring fault
• Trace and cure whatever chafed the original before fitting the new one

📦 Condition

• Genuine Volvo Penta part
• Brand new
• Supplied in original or equivalent packaging
