Generator Fault Finding and Diagnostics
A generator that is not working correctly should be properly diagnosed before parts are replaced. Our repair process focuses on identifying the underlying fault so that the correct repair can be carried out.
Depending on the fault, we may inspect the generator’s starting system, battery, fuel supply, engine, alternator, electrical connections, protection systems, controller, cooling system and voltage output.
This approach helps avoid unnecessary parts replacement and allows the generator problem to be addressed as accurately as possible.

Generator Alternator and Electrical Repairs
A generator may have a running engine but still fail to provide usable electrical power. Problems with the alternator, AVR, wiring, connections, controller or voltage regulation can affect generator output.
We can investigate generator electrical faults and determine whether the problem is related to the alternator, voltage regulation, control system or another part of the generator.
Generator Controller and Starting Problems
Modern generators rely on controllers and electrical protection systems to monitor and control generator operation. A controller fault, sensor problem, battery issue or starting-system failure can prevent the generator from operating correctly.
Our generator fault-finding service can help identify problems affecting starting, shutdowns, alarms, voltage, frequency and other generator operating conditions.
Emergency Generator Repairs for Businesses
For businesses, generator downtime can affect operations, security systems, refrigeration, equipment and essential electrical services. A reliable backup generator is particularly important when mains electricity is unavailable.

Common Emergency Generator Problems
Why won’t my generator start?
A generator may fail to start because of a weak battery, starting-system fault, fuel problem, electrical fault, controller issue, sensor problem or an engine-related fault. Proper diagnosis is required to determine the actual cause.
Why does my generator start and then stop?
A generator that starts and then shuts down may have a fuel supply problem, low oil pressure, overheating issue, sensor fault, controller fault or another protection-system problem.
Why is my generator running but not producing electricity?
This can be caused by problems involving the alternator, AVR, electrical connections, excitation system or control system. The generator should be tested to identify the cause.
Why is my generator overheating?
Overheating can be associated with cooling-system problems, radiator restrictions, coolant issues, fan or belt problems, thermostat faults or other engine-related conditions.
