Yes, we repair generators in Ruimsig, on plots and smallholdings as well as in the estates. We are open 24/7 and arrive within 1 hour for breakdowns; each callout starts with a diagnosis on site and a written quote.
Ruimsig sits on Roodepoort’s western edge, where suburbs give way to smallholdings, with security estates, larger homes and the Ruimsig Stadium in between, and Little Falls, Strubens Valley and Muldersdrift as neighbours. Properties are bigger here, and so are the jobs a generator has to do.
On a plot, the set may run a borehole pump, an electric fence, gate motors and the house at once, often with its own diesel tank. Pumps draw a heavy surge as they start, and diesel stored for months can collect water and sludge. On a Ruimsig visit we check the set’s rating against your loads, test the voltage while the pump starts, inspect the fuel in the tank and trace the fault. In the estates, we focus on automatic start and changeover on larger home sets.

Ruimsig faults come from heavier loads and stored fuel more often than in the suburbs closer to town.
We measure the voltage and speed drop at pump start-up and check the governor, AVR and set size.
Water and sludge in stored diesel block filters. We drain, inspect and clear the fuel system.
We test the controller, mains sensing and battery.
We check the radiator, coolant, fan belt and airflow on sets that run pumps for hours.
A pump can stall a set that runs the house without trouble, because its starting current is far higher than its running current. We check the pump against the set’s rating and test it running. We also inspect the diesel in your tank, because fuel stored for months can gather water and sludge that blocks filters at the worst moment. Keep the tank topped up and the cap sealed to limit condensation.
Ruimsig properties run larger diesels than most of Roodepoort, from plot sets with their own tanks to automatic standby sets in estate homes.
We service and repair the brands below. Tell us the set’s kVA and what it needs to run, including any pumps.
Sets that run boreholes, fences and gates, checked against those loads and their fuel supply.
Larger automatic home sets serviced and tested with a simulated mains failure.
Bigger standby sets serviced and repaired on site.
Motor loads are checked as they start, not just at idle.
We inspect stored diesel because it causes many plot breakdowns.

The pump draws a heavy surge as it starts. If the governor, AVR or set size cannot cope, the engine slows and the voltage drops. We measure it on site and recommend the fix.
It can block filters and starve the engine, and water in the fuel can harm the injection system. We inspect the fuel and clear the system if it is contaminated.
