| Symptom | Cause | Remedy |
|---|---|---|
| Engine Not Starting/Running Abnormally | Engine Stopped No Electric Current Tripping of Circuit Breaker Load connected to generating set during start-up Start and Stop control ON or OFF Oil level too low Unsuitable fuel level too low Fuel valves closed Clogged fuel filter Clogged fuel strainer Clogged air filter Faulty spark plug Fuel supply blocked or leaking Blocked ventilation inlets Circuit protectors not actuated Faulty appliance supply cord Faulty electrical sockets Faulty alternator Device connected or faulty cord Overload | |
| No AC output | Circuit breaker in OFF position | Switch circuit breaker to ON |
| No AC output | Circuit protector popped out | Press circuit protectors |
| No AC output | Engine not operating at rated RPM | Adjust engine running at normal operating temperature to 3750 ± 100 RPM |
| No AC output | Circuit breaker or receptacles faulty | Test for voltage at circuit breaker and receptacles |
| No AC output | Stator is faulty | Test for voltage and resistance |
| No AC output | Brushes are faulty | Test for resistance between brushes and slip ring |
| No AC output | AVR is faulty | Test for voltage |
| Low voltage at stator | Field polarity was lost | Flash rotor field |
| Alternator can't output rated power | Engine not operating at rated RPM | Adjust engine running at normal operating temperature to 3750 ± 100 RPM |
| Alternator can't output rated power | Overload condition | Calculate electrical power required by electric appliances (in Watts). Reduce total wattage of connected electric devices within application range |
| Alternator can't output rated power | Appliance is faulty | Repair faulty appliance |
