What the team works on
What does a generator specialist visit cover?
A specialist visit starts with the complaint. A set that will not start is not treated as an alternator fault, and a set that runs with no voltage is not treated as a fuel fault. The checks follow the symptom.
Diesel, petrol and supported gas sets are all in scope, as are the electrical jobs that sit beside the engine: AVR and voltage faults, controllers, fuel systems, alternators and rewinding when the tests point there. Load bank testing is available when the question is whether the set can carry a defined load.
Sizes run from portable frames to large standby plant. Makes and models are listed on their own page. Gauteng coverage is listed by region. None of that is a ranking claim, and none of it is a manufacturer authorisation.

The work
Repair, service and the systems around the engine
Generator repair specialists
Faults are tested on site and quoted before parts are replaced.
Generator service specialists
Scheduled servicing follows the make, the hours and the condition of that set.
Diesel generator specialists
Standby and commercial diesels, including fuel, cooling and output.
Petrol generator specialists
Portable and smaller petrol sets, including fuel that has been standing.
Gas generator specialists
Supported gas and dual-fuel sets. Gas work is not a DIY visit.
Generator electrical faults
No output, low voltage and wiring faults once the engine is running.
AVR and voltage faults
Unstable or missing voltage is checked at the regulator before a rewind is recommended.
Controllers
Alarms, failed automatic start and shutdowns are read on the panel.
Fuel systems
Filters, air, contamination and delivery. Injection calibration is not offered as a DIY step.
Alternators and rewinding
Winding faults are assessed after excitation and the AVR have been ruled out.
Load bank testing
Used when a start does not answer the capacity question.
Commercial and industrial generators
Larger sets stay on site. Access and kVA are part of the booking.

When our 3-phase diesel plant started smoking, their heavy-plant mechanics traced the issue to a microscopic crack in an injector line and fitted specialized parts within hours.
Common Questions
Questions about generator specialists
What does ProService Generator Repairs specialise in?
Onsite generator repairs, servicing and maintenance across Gauteng, including diesel, petrol and supported gas sets.
Do you work on electrical faults as well as engines?
Yes. Voltage, AVR, controllers, alternators and rewinding are part of the work when the tests lead there.
Are you a manufacturer dealer?
No. The company is independent. Brand pages describe sets we service. They are not an accreditation.
Do you cover large and small generators?
Yes. Size is taken from the data plate. Portable sets and large standby plant are booked differently because the access and the work differ.
Can you identify the make if I only have a photo?
Often, yes. A data-plate photo is the useful one. The makes and models page lists the brands that already have a page.
Where in Gauteng do specialists travel?
Johannesburg, Pretoria, Sandton, Centurion, Midrand, the East Rand, Randburg, the West Rand and the Vaal, with suburb pages under those regions.
How do I book?
Call, WhatsApp or the form. Send the suburb, the fault and a plate photo if you have one. A generator callout page explains the steps.
Still unsure what the fault is? Call or WhatsApp 082 057 4605 for onsite diagnosis.
