Diagnostic entry symptoms
No-start or start-and-stop
Low or no AC output
Frequency/voltage instability
Overload or overtemperature shutdown
Measurement and test approach
Measure AC voltage and frequency at no load and under staged load.
Check battery voltage and starter voltage drop during cranking.
Compare fuel consumption/run time and thermal state with actual load level.
Root-cause discrimination
Separate engine fuel/ignition/compression problems from generator-head, inverter or AVR faults.
Differentiate true overload from a sensor/protection false trip using measured current and output.
DTC / SPN / FMI context
Preserve controller fault code, shutdown reason, AC measurements and load at event time.
Post-repair verification
Run at staged load until thermal stability; voltage/frequency must remain stable and no shutdown/fault should return.
Electrical and network
Generator controller, AC output, battery/starting system, inverter/AVR and protective shutdown inputs are evaluated together.
Sensors, actuators and observation points
