On a Hyundai, we start from the symptom. We prove fuel, spark and compression before we strip a carburettor, and we measure the output once the engine runs steadily. Servicing follows the schedule in the owner’s manual for your model.
On inverter models, we test the inverter module and the electronic throttle control before ordering a model-specific part.
On conventional sets, an AVR or a capacitor holds the voltage, and a fault there is a common reason a set runs but gives no power.
Electric-start models add a battery and a starter circuit, and we check those first when the set only clicks.
