AVR replacement should match alternator model, sensing voltage, excitation requirements and wiring layout.

Before replacing the AVR, check whether low or unstable voltage is caused by speed, overload, wiring, blown fuses or excitation loss.

After replacement, voltage adjustment and stability should be tested under load.

Field Checks

  • Generator nameplate, engine model, alternator model and controller model.
  • Clear photos of the old part, connector, label and mounting location.
  • Quantity needed, urgency, destination country and preferred shipping method.

Checklist

  • Confirm alternator model
  • Check sensing voltage
  • Inspect fuses
  • Match wiring
  • Load test

Common Mistakes

  • Ordering by generator power only instead of exact engine or alternator model.
  • Ignoring connector type, voltage, sensor type or software settings.
  • Buying emergency parts without planning a normal spare stock list.
