Steco Generator Repairs & Servicing

The SG-7900A is unusual for a petrol set: its built-in automatic transfer switch lets it start and take over the load when the mains fails. When that does not happen, we test the start circuit, the battery and the transfer switch in turn.

We diagnose smaller conventional models such as the SG-2800, and the 3,300 W inverter, as portable sets. The inverter has a low-oil shut-off, so if the engine stops soon after starting, we check the oil level first.

What We Check First on a Steco

The load the SG-7900A inherits
The SG-7900A is rated 6,800 W with 7,500 W surge. When it takes over automatically, everything that was running on the mains comes with it, so we check the load it inherits.
A battery ready for the next outage
An auto-start set needs a charged battery the moment the mains fails. We test the battery and check how it is kept charged between outages.
Petrol or gas Steco
Steco also sells gas and dual-fuel sets, covered on our Steco gas page. The data plate tells us which fuel system we are working on before we arrive.

Steco Petrol Generator Repairs and Servicing

On a Steco, 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.

Auto-start models add a start controller and a transfer switch, and we test both when the set does not take over the load.
