Why specialists
What makes us generator specialists?
We have repaired generators since 2000. In 26 years we have worked on small petrol frames, home standby sets and large industrial diesels, at homes, businesses and industrial sites across Gauteng.
A generator is an engine and an alternator joined by a control system. Many faults sit where those meet: a set that runs but gives no power, a controller that blocks a start, or an AVR that lets the voltage drift. Charlie’s mechanical and electrical training means we test both sides before we name a part.
We service and repair Perkins, Cummins, Caterpillar, FG Wilson, Deutz, Kohler, Generac, Honda and Yamaha generators, and the other brands we list. We work on diesel, petrol and gas sets, from portable units to industrial plant.

Lead technician
Charlie, our lead technician
Charlie leads our technical work on diesel, petrol and gas generators. Each qualification covers a different part of the machine.
Degree in Mechanical Engineering
The engine side: combustion, fuel delivery, cooling, lubrication and the wear that leads to breakdowns.
Degree in Electrical Engineering
The output side: alternators, AVRs, controllers and the wiring between the generator and your building.
Diesel Plant Fitter
The trade skills to strip, repair and rebuild diesel plant, from small standby sets to large industrial engines.
Our skills
Engine and electrical work under one roof
Diesel engines
Fuel systems, injectors, cooling, oil pressure and starting faults on standby and prime diesel sets.
Petrol generators
Carburettors, spark plugs, stale fuel, and pull or electric start on portable and inverter sets.
Gas generators
Gas and dual-fuel sets, including the regulator and the fuel selector.
AVR and voltage
We test the automatic voltage regulator and the excitation when voltage is low, high or unstable, before anyone talks about a rewind.
Alternators
Winding tests, bearings, diodes and rewinding when the tests show the windings have failed.
Controllers
Deep Sea, ComAp, SmartGen and Datakom modules: alarms, inputs, automatic start and reprogramming.
Changeover and ATS
We test the transfer itself, because a set that starts on the key may still fail to take the load.
Load bank testing
We prove the set can carry its rated load, not only that it starts.
