Repairs
Generator faults we fix in Centurion
ATS and changeover problems
The set runs but the building stays dark, or the load never returns to the mains.
Battery and charging faults: Battery not charging
Chargers, charge alternators and batteries that cannot crank the set when the mains fails.
AVR and voltage faults: Voltage problems
Low, high or swinging voltage from the AVR, exciter or rotating diodes.
Surging and hunting
Engine speed that wanders: governors, actuators, fuel supply and air leaks.
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.
Office parks
Techno Park server rooms and the UPS hand-over
Many Centurion offices trust the building set to take over from the server room’s UPS within seconds. If voltage or frequency wanders as load steps on, the UPS refuses it and drops the racks with the engine running.
In a shared park the set may belong to the landlord and the diesel to a facilities contract. We agree who approves the quotation and who hears before a transfer test, then trace the fault to the governor, AVR, controller or changeover panel.
- Access and permits arranged with park management
- Transfer test booked for an hour facilities chooses
- Frequency and voltage watched with the UPS on line
Response
On site in Centurion in 1–2 hours
Technicians on site in 1–2 hours, 24/7. Centurion lies on the N1 between Johannesburg and Pretoria, with the N14 and the R21 close by, and Olievenhoutbosch sits on the R55 near its junction with the N14, so every suburb is reached from either city. Say whether the set is in a park, behind an estate boom, in a yard or on a plot, and who signs us in.
Meanwhile, check only the fuel gauge, emergency stop, main breaker and controller screen; leave the changeover and fuel lines alone, and stop after two tries at the start button. WhatsApp a photo of the controller and nameplate; emergency generator repair covers night calls.
Every make
Generator makes we repair across Centurion
We Service & Repair All Generator Brands. Parks and hospitals here mostly run Cummins, Perkins, Volvo Penta or John Deere engines with Stamford or Leroy-Somer alternators and Deep Sea Electronics or ComAp controllers. Estate gates and Hennopspark yards add silent diesels from Kipor, Pramac, Mac Afric and Bundu Power on SmartGen modules; Olievenhoutbosch portables include Honda, Ryobi and Lutian petrol units. See our brand pages.
Prevention
Repeat breakdowns in Centurion, and how servicing ends them
A second callout means the cause outlived the repair: a new Copperleaf gate battery goes flat if the faulty charger stays, a Techno Park set the UPS refused is refused again if its governor was never set under real load, and a dust-packed Hennopspark radiator overheats in the next long outage.
Servicing breaks that pattern. Our Centurion generator service and maintenance page covers the visit, the intervals load shedding forces and plans for landlords and HOAs. How we repair generators explains fault-finding; we also work in Irene, Laudium and Erasmia and Midrand, and across the Centurion hub.

FAQ
Frequently asked questions
Our UPS at Highveld Techno Park stays on battery when the generator runs. Why?
Voltage or frequency leaves the UPS’s window as load steps on, usually from a governor, actuator or AVR fault, or air in the fuel. See frequency and speed problems.
Can your technician get into Copperleaf, Blue Valley and the other security estates?
Yes. Book us in with the estate office or security, give us the contractor hours, and say whether the set serves the gate, a pump or a house.
Our Hennopspark compressor trips the generator when it starts. Can that be fixed?
Often. A motor start draws several times its running current, so a set near its limit dips until protection opens. We measure the dip and check the governor and AVR; see shutting down or tripping.
Do you repair petrol generators at shops and homes in Olievenhoutbosch?
Yes, at spaza shops, churches, schools and homes. Stale petrol and overloaded extension leads cause most faults. Run a portable outdoors only, and never connect it to the house through a plug.
