Overview
Generator AVR Repair & Replacement covers inspection of the Automatic Voltage Regulator where the generator design uses an AVR for output voltage control. A faulty AVR may be associated with low, high, unstable or missing output voltage, although similar symptoms can also come from other generator components. The technician should test the relevant electrical system before deciding that the AVR needs replacement. If replacement is required, confirm that the selected AVR matches the generator model and specifications and agree on the part price and installation charge.
