Automatic Voltage Regulator (AVR)
The AVR governs the excitation voltage sent to the rotor. If the solid-state components within the regulator fail due to thermal stress or voltage spikes, the rotor magnetic field collapses, preventing the stator from inducing an electromotive force (EMF) for power output.

Carbon Brush Assembly
These brushes maintain a physical electrical connection between the stationary AVR and the spinning rotor slip rings. In units with low usage, the brushes can stick in their holders or the slip rings can develop an oxide layer that increases resistance beyond the excitation threshold.

Main AC Circuit Breaker
The circuit breaker is the final mechanical gate for current leaving the stator. If the internal thermal-magnetic latching mechanism fails or becomes desensitized, it may remain in a 'tripped' state internally even if the switch appears engaged, severing the path to the outlets.
