We repair and service commercial generator sets powered by SDEC (Shanghai Diesel) engines across Gauteng. SDEC sets usually carry an alternator and controller from other makers, so we record all three and price each repair separately.

Independent service and repair: SDEC is a trademark of its owner, and ProService Generator Repairs is not a SDEC dealer or agent.

SDEC Diesel Generator Repairs

SDEC engines are common in commercial generator sets built by local and international integrators. The alternator and controller brands change the electrical work, so we write them down at the start.

We then test start, fuel, cooling, controller and output in turn.

SDEC Diesel Generator Servicing

We change SDEC engine oil and filters to the engine plate schedule, and test the battery charger output on commercial standby sets.

We record the controller and alternator makes at each service, because they are rarely SDEC-branded.

SDEC Diesel Generator Sizes We Service

We work on SDEC-engined commercial sets where access allows. The installation plates give us the kVA, alternator and controller.

Why an SDEC diesel generator will not start

When an SDEC genset will not crank, we check the battery, the starter and any panel inhibit.

When it cranks without firing, we trace the fuel filter, air in the lines and the solenoid.

Fuel delivery, injectors and pumps

We confirm the filter and lift pump on the SDEC engine before any injection work.

Smoke under load can come from fuel delivery or from an overloaded alternator, so we test both before we name an injector.

Controllers, ATS, cooling and output

SDEC installations usually use DSE or SmartGen panels. We read the alarms as displayed and trace them for that controller.

When the set runs but the building does not transfer, we test the ATS and the panel’s start output.

For overheating, we check coolant, the radiator and the fan.

We measure voltage at the breaker and AVR once engine speed is stable, and record the alternator make for the right parts.

What We Check During an SDEC Generator Repair

We check the SDEC engine, the alternator and the controller as separate scopes.

  • Fuel solenoid where fitted
  • Lift pump where fitted
  • Injectors where symptoms indicate
  • Cooling pack and airflow
  • Engine speed and frequency
  • AVR where fitted
  • Alternator and socket or breaker output
  • ATS or start-signal path where relevant
  • Canopy airflow where enclosed
  • Battery charger output
  • Glow or preheat circuit where fitted
  • Radiator face and hose condition
  • Transfer test where ATS fitted

SDEC Generator Repair or Service?

Book a repair when the genset fails to start, trips on load or loses output.

Book a service when fluids are due and the set still exercises normally.

SDEC Generator Problems Under Load

An SDEC engine can idle smoothly and hunt under commercial load. We compare fuel delivery and alternator capacity with the load applied.

Is an SDEC Generator Worth Repairing?

A fuel or cooling repair is usually worthwhile. Major engine work on a high-hour commercial genset needs a comparison with replacement.

When the engine, alternator and panel all need major work, we price a complete replacement set alongside the repair.

What Affects SDEC Generator Repair Cost?

Costs split across the SDEC engine, the alternator and the controller. AVR replacement typically costs R2,200 to R9,000, and alternator rewinding R6,000 to R18,000 or more.

Common SDEC Diesel Generator Faults

The SDEC faults we see most often, and our first checks.

SDEC engine, other alternator

We record the alternator make and test it separately.

Cranks, no fire

The fuel filter, air in the line or the solenoid.

Overheat

Coolant, the radiator or the fan.

Runs, no transfer

The ATS or panel, while the engine runs normally.

Low voltage

The AVR or alternator, once engine speed is stable.
