1140072 Suppression Kit | Genuine Volvo Penta Part

🔧 Product Description

A genuine Volvo Penta electrical suppression assembly designed to reduce radio-frequency and ignition-system interference generated by the engine charging, ignition or instrument circuits. The suppressor is installed in the applicable electrical circuit where unwanted noise is being transmitted into marine radios, audio equipment or navigation electronics. Volvo Penta supplies the suppressor as a complete serviced assembly rather than as separately replaceable internal capacitors or filter elements.

🔌 Function

The kit attenuates high-frequency electrical noise before it can travel through the vessel wiring and interfere with radios, speakers, instruments or electronic navigation equipment.

⚠️ Common Signs of Failure

• Alternator whine is heard through speakers or radio
• VHF reception deteriorates when the engine is running
• Electronic displays show noise or unstable readings
• Interference changes with engine speed
• Suppressor wiring or terminals become loose, corroded or heat damaged

🛠️ Service Notes

• Fit the suppressor as a complete unit — it is supplied as a sealed factory assembly rather than as separately replaceable capacitors or filter elements, so a faulty one is renewed whole.
• At under 50 g this is a light in-line component rather than a structural part; mount it clear of moving parts and away from heat so vibration does not work the leads loose or chafe them over time.
