Frequently searched by product codes 1493958080, 1483693080, 5642Y1 and 5641EE, this part is aimed at professional mechanics and experienced DIY enthusiasts who need a direct replacement wiring solution for common ground-point failures.
Technical Information
- Manufacturer: Stellantis (Citroën / Peugeot)
- Model: Citroën C8; Peugeot 807
- Product Codes: 1493958080; 1483693080
- Other Numbers: 5642Y1; 5641EE
Function And Benefits
The grounding cable provides a low-resistance path between the engine/chassis and vehicle negative terminal. A correct ground is essential for:
- Reliable starter motor performance and proper alternator charging.
- Stable sensor reference voltages and ECU communication.
- Prevention of electrical noise, intermittent faults and false fault codes.
- Protection against voltage drops during high-current events.
How Replacement Is Performed
Replacement is straightforward for a trained technician or competent DIYer with basic tools. Typical procedure:
- Park vehicle on level ground and engage parking brake. Disconnect the negative battery terminal before starting work.
- Locate the existing ground strap/cable—commonly routed between the engine block, transmission or battery negative post and a chassis grounding point.
- Remove securing bolts and any retaining clips. Inspect mating surfaces for corrosion or paint that could impede contact.
- Clean contact surfaces to bare metal using a wire brush or abrasive pad. Apply a thin layer of anti-corrosion compound if recommended.
- Fit the new grounding cable, ensuring correct routing and no contact with sharp edges or hot components. Tighten fasteners to the manufacturer’s torque specification.
- Reconnect the battery negative terminal and verify continuity with a multimeter. Start the engine and check charging voltage and for absence of related electrical faults.
Installation Recommendations
- Always disconnect the battery negative terminal before removing or installing ground cables.
- Clean mating surfaces thoroughly to ensure a low-resistance connection; remove paint, rust and contaminants.
- Use the correct hardware and replace any corroded bolts or washers. Tighten fasteners to the vehicle manufacturer’s torque settings.
- Route the cable away from moving parts, sharp edges and high-temperature sources. Secure with existing clips or suitable ties.
- After installation, verify charging system voltage (typically ~13.8–14.6 V at idle with engine running) and check for eliminated intermittent faults or warning lights.
Why This Part Fails Most Often
Grounding cables typically do not have a fixed replacement interval; they can last many years but fail prematurely due to:
- Corrosion at terminals and mating surfaces from moisture, road salt and chemical exposure.
- Mechanical fatigue caused by vibration, engine movement or poor initial routing/clamping.
- Heat degradation when routed too close to exhaust components or turbochargers.
- Poor original contact (painted or dirty mounting points) leading to increased resistance, heating and eventual failure.
- Damage from accidental impacts or during other repairs.
Notes For Buyers
This part is commonly identified by the codes listed above. When replacing a ground connection, always ensure the mating surfaces are prepared correctly and that the new cable matches the original routing and attachment points to restore proper electrical performance.
