⚙️ Key Features

• 120A charging output
• Valeo-manufactured OEM alternator
• Serpentine-belt drive
• Confirmed 8.1IPSCE and 8.1IPSE applications
• Designed for the original Volvo Penta mounting and wiring layout

🔌 Function

The alternator converts engine rotation into electrical power to operate onboard systems and recharge the starting and service batteries.

⚠️ Common Signs of Failure

• Battery warning displayed
• Low or unstable charging voltage
• Repeated flat batteries
• Alternator bearing noise
• Burnt smell or overheated casing
• Excessive AC ripple affecting electronics
• Charging output changing when the harness is moved

🛠️ Service Notes

• Isolate the batteries before you start, and never disconnect the alternator or battery cables with the engine running — that will destroy the diodes
• Reconnect exactly as it came off, correct polarity, terminals clean and tight, and check the earth path through the mountings and engine is sound
• Check the pulleys line up and the belt runs true; renew a glazed, cracked or oil-contaminated belt at the same time and tension it by the procedure in the manual for your engine
• Support the alternator while you fit and tighten the mounting and adjusting bolts to the manual's figures, and never lever against the alternator body or end covers
• After fitting, confirm the charge warning goes out and charging voltage is correct, and recheck belt tension after the first running period
