| Fault Category | Symptoms | GMA Response |
|---|---|---|
| No-start / hard start | Generator cranks but does not start, does not crank, weak battery, start failure alarm. | Battery/starter checks, fuel supply checks, controller alarms, sensor review, wiring and safety interlock checks. |
| Shutdown under load | Stops when load is applied, overload, high temperature, low oil pressure, fuel starvation. | Load review, cooling and lubrication checks, fuel system diagnosis, protection/alarm review. |
| Unstable voltage | Voltage too high, too low, fluctuating, AVR alarm, sensitive equipment affected. | AVR check, alternator sensing, excitation circuit, load balance, wiring inspection. |
| Unstable frequency | Frequency drops or rises, engine hunting, speed instability. | Governor/speed control checks, fuel supply, load conditions, controller settings. |
| Overheating | High coolant temperature alarm, coolant loss, radiator blockage, fan problem, poor ventilation. | Cooling system inspection, airflow review, radiator/fan checks, coolant and hose checks. |
| Fuel system fault | Air in fuel, clogged filters, water contamination, transfer pump failure, low fuel pressure. | Filter service, leak checks, tank/day tank inspection, pump and line checks. |
| ATS / transfer fault | Generator runs but load does not transfer, utility return issue, manual/auto issue. | ATS control sequence test, interlock review, contactor/breaker checks, signal verification. |
| Control panel alarm | Sensor fault, emergency stop, communication loss, controller configuration issue. | Alarm interpretation, wiring/sensor checks, controller settings, functional testing. |
| Low output / overload | Generator cannot carry load, breaker trips, voltage collapse. | Load measurement, phase balance, capacity review, breaker/protection and alternator checks. |
