Yes, we repair generators in Roodekrans, wherever the set stands on the property. We are open 24/7 and arrive within 1 hour for breakdowns; we diagnose the fault on site first and quote the repair in writing.
Roodekrans sits on the ridge on Roodepoort’s western side, close to the Walter Sisulu National Botanical Garden, with Helderkruin and Wilro Park below it and Krugersdorp just beyond. Many homes are larger and built on sloping stands, and the generator often stands at the bottom of the garden or beside the driveway, some distance from the distribution board.
Distance brings its own problem. A long or undersized cable between the set and the house drops voltage, so lights dim and motors struggle even though the generator itself reads normal. On a Roodekrans visit we measure voltage at the set and at the board, check cable size and connections, and confirm the set is large enough for pool pumps, gates and the rest of the house. Steep driveways also matter, so tell us about access when you book.

What happens next
Charlie, lead technician: Degree in Mechanical Engineering, Degree in Electrical Engineering, Diesel Plant Fitter. Generator specialists since 2000.
On larger Roodekrans properties, the distance between the generator and the house causes as many complaints as the engine does.
If the set reads normal but the house is dim, we check cable size, joints and connections along the run.
We check the breaker, the motor’s starting surge and the set’s rating.
We test the mains sensing, the controller and the battery on larger automatic sets.
We meter the output with your loads running and trace hunting to the AVR or governor.
Voltage drop grows with cable length and load, so a set at the bottom of a large garden can deliver noticeably less at the house than at its terminals. We measure both ends under load and tell you whether the answer is a cable upgrade by your electrician, a better connection, an AVR adjustment or a larger set. We never guess from the generator’s own meter alone.
Roodekrans homes tend to run larger automatic diesel sets, with some gas and petrol units.
We service and repair the brands below. Send the kVA rating and a rough idea of the cable distance to the house.
Bigger automatic sets serviced and tested with a simulated mains failure.
Sets away from the house, with voltage measured where it is used.
Motor loads checked against the set’s rating and breaker.
Voltage where you use it matters more than voltage at the set.
