🔌 Function

Controls the alternator's field current so charging voltage stays within limits as load and speed change.

⚠️ Common Signs of Failure

• Charging voltage too high, boiling or gassing the batteries
• Charging voltage too low so the batteries never come up
• Voltage swinging about at steady engine speed
• Charge warning lamp flickering with the engine running
• Regulator body heat-marked or its connections arced

🛠️ Service Notes

• Measure charging voltage at the battery before ordering — a flat battery is often a cable or earth fault rather than the regulator
• Alternator 873986 is the 28V 60A unit listed alongside if the fault is in generation rather than regulation
