Description

The Volvo Penta 889730 is a genuine Volvo Penta OEM ground / earth cable used as diagram-specific electrical bonding hardware on select Volvo Penta marine engine assemblies. This cable provides a low-resistance ground connection between specified engine components and the engine grounding system, helping maintain proper electrical continuity where the Volvo Penta parts diagram calls for 889730.

Key Features

• Genuine Volvo Penta factory OEM ground cable.
• Volvo Penta part number: 889730.
• Also commonly described as an earth cable or bonding cable.
• Listed weight: 0.014 kg, approximately 0.03 lb.
• Used in select engine cooler, heat exchanger, electrical grounding, and bonding locations where specified by Volvo Penta diagram.
• Helps maintain electrical continuity between metal engine components and the engine ground circuit.
• Important for cooling-system components and engine-mounted hardware where proper bonding is required.

Application Compatibility

Common application context includes select Volvo Penta engine assemblies where the parts diagram calls for 889730, especially grounding or bonding locations associated with:

• Engine-mounted cooler assemblies
• Heat exchanger assemblies
• Oil cooler or cooling-system housings where specified
• Electrical ground / earth bonding points
• Metal components requiring continuity to the engine ground system

Use this cable only where the Volvo Penta parts diagram specifically calls for 889730.

Fitment Notice

Confirm fitment by Volvo Penta engine model, serial number, cooler or heat exchanger diagram, terminal location, and cable routing before ordering. Volvo Penta uses different ground leads, bonding straps, battery cables, and electrical jumpers across engine families, so cable length, terminal style, and mounting point must match the original diagram.

When This Part Needs Replacement

Replace this ground cable if the original lead is missing, corroded, loose, oil-soaked, heat-damaged, frayed, broken, or has damaged terminals. It should also be replaced if there is poor continuity between the bonded component and engine ground, unexplained electrical faults, sensor irregularities, or visible corrosion around the cooler or heat exchanger bonding points.

Installation Notes

Install this cable only in the exact Volvo Penta diagram location that calls for 889730. Clean the contact surfaces before installation so the terminals seat against bare, conductive metal where required. Inspect the mounting screws, washers, cooler housing, heat exchanger body, terminal eyelets, and surrounding wiring while the cable is removed. Route the cable away from hot exhaust parts, sharp edges, belts, and moving components.

Parts Desk Insight

Ground and bonding leads are small parts, but they play an important role in marine engine electrical health. A loose or corroded bonding cable can create poor continuity between cooling-system components and the engine ground circuit, so the cable and its contact points should be inspected together rather than replacing the lead alone.
