⚙️ Key Features

• 28 V, 100 A
• 12.300 kg
• Supersedes 3803499, 848571 and 862514, previously covering a rectifier plate and a remanufactured alternator
• 109 applications across six engine series

🔌 Function

Generates the charging current for the 28 volt system and holds the batteries at their regulated voltage while the engine runs.

⚠️ Common Signs of Failure

• Charge warning lamp on or flickering
• Batteries going flat or needing repeated charging
• Whine, growl or bearing rumble from the alternator
• Burnt insulation smell or scorching at the terminals
• Voltage reading low, unsteady or too high at the batteries

🛠️ Service Notes

• Isolate the batteries before disconnecting the alternator, and never break a battery connection with the engine running, as the surge will damage the charging and control electronics
• One of the numbers it replaces was catalogued as a rectifier plate, so a component-level repair is no longer the route and the complete unit is what is now supplied
• Check the belt, tension and pulley alignment when fitting, since a slipping belt will look exactly like a failed alternator
