Repairs
Generator faults we fix in Weltevreden Park
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.
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.
AVR and voltage faults: Voltage problems
Low, high or swinging voltage from the AVR, exciter or rotating diodes.
Overheating
Shutdowns from blocked radiators, failed fans, thermostats and coolant leaks.
Constantia Kloof
Buildings let with full generator backup
Some Constantia Kloof office buildings are let with full generator backup, so the set is a term of the lease. It stands in a caged yard or basement plant room, the facilities manager holds the keys, and every floor notices when the changeover fails.
We work inside the hours the building allows, test the transfer while the floors are quiet and leave the controller in automatic. At the dealerships the question is load: compressor and lifts start together, and a set near its rating sags until it trips.
- Keys and test hours arranged with the facilities manager
- Transfer tested with the floors quiet, then back to automatic
- Workshop starting loads measured against the set’s kVA

Response
On site in Weltevreden Park in 1–2 hours
Technicians on site in 1–2 hours, 24/7. Hendrik Potgieter Road, Christiaan de Wet Road and the N14 serve the area, so a technician reaches Constantia Kloof, Allen’s Nek or Ruimsig from either side. Say whether the set is behind office-park security, at an estate gate or on a holding, where a pin helps.
While you wait, keep to the safe checks: fuel level, main breaker, emergency stop and controller screen. Press start twice at most and leave the changeover panel shut. A photo of the controller and nameplate saves a second trip; emergency generator repair covers calls at night.
Every make
Makes we repair in Weltevreden Park
We Service & Repair All Generator Brands. Here the landlord and mall sets are three-phase canopies, typically a Cummins, Perkins or Deutz engine with a Stamford or Mecc Alte alternator and a Deep Sea Electronics or ComAp controller. At complex gates, consulting rooms and Ruimsig holdings the silent diesels are smaller: Kipor, Bundu Power, Pramac, Mac Afric and Lutian units on SmartGen modules. Our brand pages cover each make.
Prevention
Why the same Weltevreden Park set calls twice
A second callout means the first cause is still there: a new gate battery under a charger nobody metered, a holding set refilled from a drum with water in it, a changeover that hesitated a month later. We clear the fault; the job card lists the rest.
Servicing stops the repeat. Our Weltevreden Park generator service and maintenance page sets out the visit, the intervals a month of load shedding brings forward, and the plans landlords and HOAs use. Generator repairs explains how a fault is traced; we also cover Roodepoort, Honeydew and Randburg, and across the Roodepoort hub.

FAQ
Frequently asked questions
Our Constantia Kloof lease promises full generator backup. Who do you report to when it fails?
Whoever books us, usually the landlord’s facilities manager, with a written report tenants can see. A tenant can call first; the landlord’s go-ahead comes before work starts.
Our dealership set trips when the compressor and a lift start together. Is it faulty?
Often it is short of kVA rather than broken: motors draw several times their running current to start. We measure the starting load and say whether the set copes; see shutting down or tripping.
Do you come out to the Ruimsig smallholdings and estates?
Yes. Send a pin and the gate arrangement. Holding sets stand idle between outages, so we check the stored diesel and water separator too, and watch the set take the pump if it runs one.
Can you repair a shop’s generator at Clearwater Mall or Allen’s Nek while it trades?
Mostly yes: diagnosis and parts work happen with the shop on mains and the set isolated; the transfer test, which puts the tills on the generator briefly, is booked outside trading hours.
