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.
