Generators we work on in Cullinan
Guest houses in the old mine houses: Standby generators
Silent diesel standby sets that keep rooms, kitchens and lights going for overnight visitors when an outage lands after dark.
Restaurants, venues and visitor shops: ATS and changeover problems
Sets carrying cold rooms, tills, sound and lighting, where a failed transfer halfway through a wedding or lunch rush costs the most.
The mine and its contractors: Industrial generator services
Diesel sets run by contractors at the mine for site offices, workshops and equipment, worked hard in dust and long shifts.
Farms and smallholdings: Diesel generators
Generators between Cullinan, Rayton and Pretoria’s eastern edge, carrying farmhouses, pumps, cold storage and workshops through long outages.
Homes and shops in Refilwe: Portable and inverter generators
Portable petrol and small diesel units at homes and small shops, repaired and checked for overloads and unsafe extension leads.
Schools and clinics: Commercial generator services
Standby sets at schools and clinics in Cullinan, Refilwe and Rayton that sit unused for weeks, then must start first time.
Repairs
Generator faults we fix in Cullinan
Generator won’t start: Generator not starting
Flat batteries, failed chargers, stale fuel and starter faults, fixed on site.
Fuel and injector faults: Fuel system repairs
Contaminated diesel, blocked filters, air in the lines, lift pumps and injectors.
Battery and charging faults: Battery not charging
Chargers, charge alternators and batteries that cannot crank the set when the mains fails.
ATS and changeover problems
The set runs but the building stays dark, or the load never returns to the mains.
Overheating
Shutdowns from blocked radiators, failed fans, thermostats and coolant leaks.
AVR and voltage faults: Voltage problems
Low, high or swinging voltage from the AVR, exciter or rotating diodes.
The village
Guest houses and restaurants in the old mine village
Cullinan grew up around the mine where the Cullinan diamond was found in 1905, and many old mine houses now serve visitors as guest houses, restaurants and shops. They came long before anyone planned a generator, so the set stands wherever there was room.
That brings its own faults: a canopy against an outbuilding breathes its own hot air, an exhaust ends near a window, and a changeover added later carries more than it was wired for. We check all three during the repair.
- Airflow and exhaust routing checked where the set is boxed in
- Changeover tested with kitchens and cold rooms on load
- The set left in automatic before we go
Response
On site in Cullinan in 1–2 hours
Technicians on site in 1–2 hours, 24/7. Cullinan lies east of Pretoria, and the R515 links the town, Refilwe and Rayton to the N4. For a farm, send a map pin and gate details; for the mine, tell us who clears contractors in.
While you wait, check the fuel, the emergency stop and the controller screen, and stop cranking a set that fires and dies. Run a portable outdoors only and never plug it into a wall socket; fuel lines and the changeover are the technician’s job. See emergency repairs.
Every make
Generator makes we repair around Cullinan
We Service & Repair All Generator Brands. Guest houses and homes mostly run silent diesels from Bundu Power, Kipor or Pramac; Refilwe’s shops favour Honda and Ryobi portables. Farm and contractors’ sets are heavier diesels on Perkins, Deutz, Cummins or John Deere engines, with Stamford or Mecc Alte alternators and Deep Sea Electronics or SmartGen controllers. See our brand pages.
Prevention
Why Cullinan generators break down again
A set that failed on stale diesel fails again if the same drum feeds it, and a new guest-house battery goes flat again if the set stands six weeks without a run. The repair fixes the fault we came for; the job card notes the rest.
Servicing is what breaks the cycle. Our Cullinan generator service and maintenance page covers a service for a guest house, farm, contractor’s set or school, and how often each needs one. How we repair generators explains our fault-finding. Nearby we also repair sets in Mamelodi, Kameeldrift and Bronkhorstspruit, with the wider east on our Pretoria East page and the city on the Pretoria hub.

FAQ
Frequently asked questions
Do you come out to farms and smallholdings between Cullinan and Rayton?
Yes. Send a map pin, the gate or farm name and who will meet us, plus a photo of the nameplate. We repair farmhouse standby sets, open-frame diesels and the generators behind pumps and workshops.
Our venue’s generator runs but the hall stays dark. Can you come before the function?
Yes, we work 24/7. A set that runs without carrying the load usually points to the changeover or a tripped breaker. Leave the changeover panel closed; it needs a technician.
Do you fix small petrol generators for homes and shops in Refilwe?
Yes: carburettors, recoil and electric starts, AVRs and overload damage. Always run a portable outdoors, away from windows, and never plug it into a wall socket to feed the house.
Our diesel has stood in drums for months. Could that stop the set starting?
Often, yes. Stored diesel collects water and sludge that block filters and injectors. We drain and clean the fuel system; our fuel contamination guide explains how to store it better.
