Louis Botha Avenue shops and car dealers: Commercial generator services
Car dealers’ workshops with compressors and vehicle lifts, and small businesses with a yard set.
Grant Avenue restaurants and Glenhazel food shops: Fuel system repairs
Kitchens, cold rooms and freezers that ride on the set through every slot.
Synagogues, churches and halls: ATS and changeover problems
Sets that must start and change over by themselves mid-service, nobody at the controller.

Community schools: Generator not starting
Sets in Glenhazel, Highlands North and Sandringham carrying office, kitchen and security, idle all holiday.
Repairs
Generator faults we fix in Norwood and Orange Grove
Generator won’t start: Generator not starting
Flat batteries, failed chargers, stale fuel and starter faults, fixed on site.
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.
Fuel and injector faults: Fuel system repairs
Contaminated diesel, blocked filters, air in the lines, lift pumps and injectors.
AVR and voltage faults: Voltage problems
Low, high or swinging voltage from the AVR, exciter or rotating diodes.
Older homes
Side passages, exhausts and the wall next door
At the older houses in Orange Grove, Orchards and Highlands North the set ends up in the side passage, exhaust run up the wall past the neighbour’s windows. The passage is the problem: the radiator draws its hot air back and boxes on the canopy close the vents.
A set that shuts down on hot afternoons is often only short of air: we clear the intake and outlet, test the thermostat, fan and coolant, and move an exhaust that ends under a window; see overheating.
- Vents and radiator cleared
- Exhaust checked for leaks and where it ends
- Never run inside a garage
Response
On site in Norwood and Orange Grove in 1–2 hours
Technicians on site in 1–2 hours, 24/7. Louis Botha Avenue is the spine of these suburbs and runs on into Houghton and the M1; Linksfield and Sandringham sit at the city’s eastern edge against Edenvale and Bedfordview, so a technician comes along Louis Botha or in from the east. Tell us who opens the gate.
While you wait, check only the fuel level, main breaker, emergency stop and controller screen; leave the changeover and fuel lines to us. WhatsApp a photo of the controller and nameplate; emergency generator repair covers night calls.
Every make
Generator makes we repair across these suburbs
We Service & Repair All Generator Brands. Here that means silent diesel sets from Kipor, Bundu Power, Pramac and Mac Afric beside homes and shops, petrol and inverter portables kept for a till or fridge, and at care homes, schools and larger shops three-phase sets on Perkins, Kubota or Cummins engines with Stamford, Leroy-Somer or Mecc Alte alternators and Deep Sea Electronics, ComAp or SmartGen controllers. See our brand pages.
Prevention
Why a Norwood or Orange Grove set fails twice
A second callout means only the symptom was treated: a new battery under a charger nobody metered, a restaurant set restarted on water-laden diesel, a passage set overheating again once the boxes return. We fix the fault and report the rest.
Servicing stops the repeat: our Norwood and Orange Grove generator service and maintenance page covers the visit at a food shop, synagogue, care home or passage set, how a month of slots brings it forward, and the plans for owners and committees. See generator repairs for how we diagnose; we also cover Parktown and Houghton, Kensington and Bruma, Edenvale and Johannesburg.

FAQ
Frequently asked questions
Our Grant Avenue restaurant loses the cold room when the generator takes over. Why?
The set is near its limit: a compressor draws several times its running current to start, the voltage dips and the protection opens. We measure the start, then stagger the compressors or say the set is too small.
Our synagogue’s generator starts but the hall stays dark. Why?
Almost always the changeover: a stuck contactor, mains sensing that still believes the supply is on, or a tripped generator-side breaker. A technician’s job, not a reset; see ATS and changeover problems.
Our care home cannot lose its generator overnight. Can you come tonight?
Yes. We work 24/7, with technicians on site in 1–2 hours. Tell reception to expect us and say what the set carries, lifts, nurse call or fridges, so the right parts come along.
Do you repair the petrol generator we keep at our Louis Botha Avenue shop?
Yes. Portable petrol and inverter sets mostly fail on stale fuel, gummed carburettors and worn pull-starts, all fixed on site. Run it outside, away from the door, with appliances plugged in directly, never a wall socket.
