Generators we work on in Silverton
Factories in Waltloo and Silvertondale: Industrial generator services
Three-phase standby sets behind production lines, compressors and extraction, in a plant room or a fenced yard behind the loading bays.
Automotive component suppliers: ATS and changeover problems
Factories in the Tshwane Automotive Special Economic Zone beside Ford’s Silverton Assembly Plant, where a failed transfer stops a line.
Warehouses and distribution: Commercial generator services
Waltloo and Silvertondale warehouses where the offices, dock doors, lighting and scanners all hang off one standby supply.
Koedoespoort workshops: Diesel generators
Standby and workshop sets in the Koedoespoort industrial area, which includes Transnet’s rail workshops.
Dealerships and main-road businesses: Standby generators
Car dealerships, showrooms and shops along Silverton’s main roads, where the set keeps tills, lights and workshop tools going.
Homes and schools in Silverton and Eersterust: Residential generator services
Silent diesel sets at family homes, portable petrol units at small shops, and school sets idle for weeks between outages.
Repairs
Generator faults we fix in Silverton
AVR and voltage faults: Voltage problems
Low, high or swinging voltage from the AVR, exciter or rotating diodes.
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.
Battery and charging faults: Battery not charging
Chargers, charge alternators and batteries that cannot crank the set when the mains fails.
Generator won’t start: Generator not starting
Flat batteries, failed chargers, stale fuel and starter faults, fixed on site.
Industrial sets
Plant rooms and motor loads in Waltloo
In Waltloo and Silvertondale the generator usually stands in a plant room beside the main switchgear or in a yard behind the factory, carrying motors rather than lights. When several start at once the voltage dips, and a weak exciter or failed rotating diode shows up as a trip.
Many of these sets were sized for the plant as it once was. We measure each phase with the machines running, because a set that copes with one line can trip the day a second line or a bigger compressor goes onto it.
- Phase currents measured with the plant running
- AVR, exciter and rotating diodes tested
- Plant-room ventilation and radiator airflow checked
Response
On site in Silverton in 1–2 hours
Technicians on site in 1–2 hours, 24/7. Silverton lies east of the Pretoria Moot, with Dykor Road linking it to the Waltloo and Silvertondale industrial areas and Eersterust towards Mamelodi. Give us the factory gate, who signs contractors in, and whether the set is in a plant room or a yard.
Until we arrive, check the fuel level, emergency stop and controller screen, and stop cranking a set that fires and dies; the changeover, fuel lines and switchgear are the technician’s work. A WhatsApp photo of the controller and nameplate gives us the make and kVA. See after-hours callouts for night shifts.
Every make
Generator makes we repair in Silverton
We Service & Repair All Generator Brands. Silverton’s factories and warehouses mostly run three-phase diesel sets on Cummins, Perkins, Volvo Penta, Deutz or John Deere engines, with Stamford, Leroy-Somer or Mecc Alte alternators and Deep Sea Electronics or ComAp controllers. Homes and main-road shops more often have silent diesels from Bundu Power, Kipor or Pramac, or Honda and Ryobi portables. See our brand pages and AVR repairs.
Prevention
Why Silverton sets fail twice
A factory set that tripped on voltage trips again if the phases stay unbalanced, and a home set that would not start on stale petrol fails the same way next winter if the tank sits half full. The repair clears the fault in front of us; the job card lists what else we saw.
Servicing is what stops the second visit. The Silverton generator service and maintenance page describes a service at a factory, warehouse, workshop or home, and the plans for each. Our generator repair service explains how we diagnose. Next door we repair sets in the Pretoria Moot, Mamelodi and Kameeldrift, and across Pretoria East and the Pretoria hub.

FAQ
Frequently asked questions
Our Waltloo factory’s generator trips when the machines start. Why?
Usually the load: motors starting together pull the voltage down, or one phase carries far more than the others. We measure each phase under load and test the AVR, exciter and diodes first.
Can you repair our plant’s generator without stopping production?
Often, yes. We work 24/7, so fault-finding and the load-transfer test can be booked between shifts or at a weekend, and we follow your site’s induction and permit rules.
Do you repair small generators at homes and shops in Eersterust?
Yes: portable petrol units, small diesel sets and home standby generators. Never feed the house by plugging a generator into a wall socket; it needs a proper changeover. See portable and inverter generators.
Do you work on standby systems at the automotive component suppliers?
Yes, including three-phase sets feeding several distribution boards and sets with automatic changeovers. When you call, tell us the kVA, the controller make and who clears contractors at the gate.
