20378934 Fuse | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta red 10-amp micro blade fuse used in engine cable-harness and fuse-panel circuits. It is rated for low-voltage vehicle electrical systems and is confirmed in the TAD734GE cable and fuse arrangement.

🚤 Compatibility

Typically suits:

• Volvo Penta TAD734GE

• Engine Family: TAD

⚙️ Key Features

• 10 A current rating
• Red micro-blade fuse format
• Nominal voltage rating up to 32 V
• Protects the assigned engine-control or accessory circuit
• Engine type: 12 V or 24 V Volvo Penta electrical systems

🔌 Function

Opens the electrical circuit when current exceeds the 10 A rating, protecting the harness and connected components.

⚠️ Common Signs of Failure

• Fuse element visibly open
• Repeated fuse failure
• Loss of the protected circuit
• Heat damage at the fuse holder
• Corroded or loose blade terminals

🛠️ Service Notes

• Always fit the same type and rating as the fuse that failed — a higher rating protects nothing and puts the load on the cable instead
• Find out why the fuse blew before fitting another; a fuse that goes again immediately is reporting a short or an overloaded circuit, not a faulty fuse
• Isolate the battery before working in a fuse box, and pull fuses with the correct puller rather than pliers
• Check the holder as well as the fuse — a corroded or slack holder overheats, discolours the fuse body and causes intermittent faults
• Keep the fuse box lid and its seals in place so the box stays dry, and carry spares of the ratings your engine uses
