Who we repair for
Generators we work on in Alexandra
Homes and backyard rooms: Portable and inverter generators
A petrol or inverter portable in the yard, running lights, fridges and chargers for the house and the rooms behind it.
Spaza shops and small retailers: Shutting down or tripping
Fridges, freezers and a card machine on a small set, where a starting compressor can drag the voltage down.
Taverns and eateries: Commercial generator services
Fridges, lights and sound through evening trading, so running hours pile up with every load-shedding slot.
Churches, schools and crèches: Generator not starting
Sets that stand for weeks between outages, then fail to start on the day they are needed.
Clinics: Battery not charging
Fridges and lights that cannot wait, often on a small electric-start diesel whose battery must stay charged.
Small workshops and car washes: kVA sizing guide
Compressors and pressure washers bring heavy starting loads, so the set must be sized for the motor.
Repairs
Generator faults we fix in Alexandra
Generator won’t start: Generator not starting
Flat batteries, failed chargers, stale fuel and starter faults, fixed on site.
AVR and voltage faults: Voltage problems
Low, high or swinging voltage from the AVR, exciter or rotating diodes.
Fuel and injector faults: Fuel system repairs
Contaminated diesel, blocked filters, air in the lines, lift pumps and injectors.
Overheating
Shutdowns from blocked radiators, failed fans, thermostats and coolant leaks.
Surging and hunting
Engine speed that wanders: governors, actuators, fuel supply and air leaks.
Battery and charging faults: Battery not charging
Chargers, charge alternators and batteries that cannot crank the set when the mains fails.
Yards and backyard rooms
One portable, several rooms and a run of extension leads
Alexandra is densely built: older houses with backyard rooms, flats, hostels and informal dwellings. One portable often feeds several households through leads strung across the yard, and each heater or kettle added pushes it towards overload. Worn brushes, failed capacitors and scorched sockets follow.
Space is tight, so sets end up in passages or hard against a wall. Run one in open air only, away from doors and windows: its exhaust carries odourless carbon monoxide. Never connect it to a wall plug; that back-feeds the network and can kill someone on the lines.
- Heavy-duty leads, one appliance each, never daisy-chained
- Engine off and cool before refuelling
Every make
Portable and diesel makes we fix in Alexandra
We Service & Repair All Generator Brands. In Alexandra that mostly means petrol portables and inverters from Kipor, Lutian, Mac Afric and others, some on Honda engines, plus open-frame and silent diesels such as Bundu Power. We clean or rebuild carburettors, fit plugs and recoil starters, and renew brushes, capacitors and AVRs; on a diesel we bleed the fuel system and change filters.
Response
On site in Alexandra in 1–2 hours
Technicians on site in 1–2 hours, and we work 24/7. Alexandra lies across the M1 from the Sandton CBD, bordered by the Wynberg and Marlboro industrial areas. Tell us whether you are in Old Alex or across the Jukskei on the East Bank or Far East Bank, the street, and whether the set is in a yard, a shop or a passage.
Until we arrive, turn the set off, take the leads out and let the engine cool. A set that coughs and stops is better left alone than pulled until the cord snaps. WhatsApp a photo of its label so we bring the likely parts; emergency generator repair covers night calls.
Prevention
Why Alexandra generators come back with the same fault
A repair holds only if the cause goes too. The carburettor gums up again on last month’s petrol, the AVR fails again when the same leads feed the same rooms, and an engine against a wall overheats again. We say plainly when a set is not worth fixing; see repair or replace.
A service between outages breaks that cycle: see our Alexandra generator service and maintenance page. The main generator repairs page explains how we trace a fault. Close by, we attend breakdowns at the workshops of Wynberg and Marlboro, in Norwood and Orange Grove and in Sunninghill and Woodmead, and across the Sandton hub.

FAQ
Frequently asked questions
One generator runs our house and the backyard rooms. Why does it keep cutting out?
Usually overload: heaters, kettles and irons on shared leads draw more than a small set gives, so its breaker trips. We measure the output and check the size; see the kVA sizing guide.
Can the generator run in the passage between our rooms if the door is open?
No. A narrow passage traps exhaust, and carbon monoxide can build up in the rooms beside it without any smell. Run the set in open air, well away from doors and windows, never indoors or in a garage.
Can you connect the generator to the house so we stop using extension leads?
Yes, safely, through a changeover switch fitted by a technician, never by plugging the set into a wall socket, which back-feeds the network. Generator installation explains how a changeover is fitted.
Do you work in Old Alex, the East Bank and the Far East Bank?
