⚙️ Key Features

• 0.034 kg
• 93 applications across AQ, AD, TAMD, D, TMD and BB series
• Shares its application list with anchorage 839342

🔌 Function

Protects a circuit by melting and breaking the connection if the current rises above its rating, so the wiring and the components it feeds are not damaged.

⚠️ Common Signs of Failure

• Circuit dead with the fuse element visibly broken
• Fuse body blackened or its glass sooted inside
• Fuse blowing again as soon as it is replaced, pointing to a fault upstream
• Fuse ends and holder corroded or discoloured
• Circuit working intermittently as the fuse loses contact in the holder

🛠️ Service Notes

• Fit only the same rating as the original — never a heavier one, since the fuse protects the cable
• Find the reason a fuse has blown before replacing it, and clean or renew the anchorage 839342 if the contacts are corroded
• Isolate the batteries before working on the circuit

📦 Condition

• Genuine Volvo Penta part
