⚙️ Key Features

• Alternator
• 6.913 kg
• Supersedes 874502, which was catalogued as a remanufactured alternator
• Covers the 32 D series engine applications of the number it replaces

🔌 Function

Driven by the engine belt, it generates the electrical output that charges the batteries and carries the vessel's electrical loads while the engine is running.

⚠️ Common Signs of Failure

• Charge warning lamp lit or flickering
• Batteries going flat or never reaching full charge
• Squealing on start-up from a slipping or glazed belt
• Whining or growling from the alternator bearings
• Burning smell, or scorched and discoloured windings found on strip-down

🛠️ Service Notes

• Check belt tension, battery condition and the main charging leads before condemning the alternator - all three give the same symptoms
• Measure the voltage drop in the charging cables and the earth return; a poor connection makes a good alternator look faulty
• An older parts list quoting 874502 as a remanufactured unit points to this number now
