Listings for Bison BS models show three-phase sets with 230/400 V outputs and electric and manual start. A three-phase petrol set needs its load spread across the phases, so when one trips or runs rough on one phase, we check for imbalance as well as faults.
We confirm from the data plate whether your Bison belongs to that range. The plate also gives the engine and rating we use to plan the visit.
Bison is also the name of a European generator brand whose petrol range, listed by a Ukrainian retailer, includes three-phase BS models with electric and manual start. Your data plate shows whether a Bison set in South Africa comes from that range.
Specifications vary by market and year, so the data plate on your Bison confirms the exact model. Sources:
Each phase of a 230/400 V set carries only part of the rating. A single-phase load bigger than one phase’s share can trip it even when the total looks well within the rating.
The 400 V between phases is more dangerous than household 230 V. Connections to a three-phase set belong in a proper distribution board and changeover, never in improvised plugs.
The BS6500-3 has electric and manual start. If only the manual start works, the battery or the start circuit is the fault.
On a Bison, 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 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.

Bison models you may own include the BS6500-3. Specifications vary by market and year, so the data plate on your generator confirms exactly which one you have.
A 230/400 V set such as the BS6500-3 can supply single-phase circuits, but the load has to be shared sensibly between the phases and connected through a proper changeover switch. We check the rating and the wiring before it is connected.
