Generator problems can range from a simple starting fault to electrical,
engine, fuel or control-system problems. Some common generator faults we
investigate include:
- Generator will not start
- Generator starts and then stops
- Generator overheating
- Low or unstable generator voltage
- Generator losing power under load
- Battery and charging problems
- Alternator and AVR problems
- Fuel-system problems
- Control-panel faults
- Electrical problems
- Generator servicing and maintenance requirements
Generator Will Not Start
A generator that will not start can have a weak battery, starting-system
fault, fuel problem, electrical fault, control-system issue or another
mechanical problem. Proper fault finding helps determine why the generator
is not starting before the appropriate repair is carried out.
Generator Starts and Stops
If a generator starts and then switches off, the cause may be related to
fuel supply, overheating, sensors, protection systems, low oil protection,
electrical faults or control-system problems. We can investigate the
symptoms and identify the likely cause of the shutdown.
Generator Overheating
Generator overheating should be investigated because excessive operating
temperatures can affect reliability and generator performance. Cooling
system problems, radiator issues, coolant circulation and other related
faults may need to be checked.
Low or Unstable Generator Voltage
Low or unstable voltage can affect equipment connected to a generator.
Generator electrical faults can involve the alternator, voltage regulation
system, wiring, connections or other electrical components. Proper testing
can help identify the cause of the voltage problem.
Generator Losing Power Under Load
A generator that runs normally without a load but loses power when
equipment is connected may have an engine, fuel, electrical or load-related
problem. The generator should be assessed to determine the cause of the
loss of power.
Generator Battery and Charging Problems
The battery and charging system are important parts of a standby
generator’s starting system. A weak battery or charging fault can result
in starting problems when backup power is required. These systems can be
inspected as part of generator fault finding.
Generator Alternator and AVR Repairs
Alternator and automatic voltage regulator problems can affect generator
electrical output and voltage stability. Where required, the generator’s
electrical system can be inspected and tested to identify the source of
the problem.
Generator Fuel System Problems
Fuel-related problems can cause difficult starting, poor running, loss of
power and unexpected shutdowns. Generator fault finding can help determine
whether the problem is associated with fuel delivery or another part of
the generator system.
Generator Control Panel and Electrical Faults
Generator alarms, warning indicators, control-panel faults and electrical
problems can affect generator operation. Our diagnostic approach focuses
on identifying the fault so that the appropriate repair can be recommended.
