The short answer
If the engine runs but house sockets stay dead, the fault may be the set's breaker, changeover switch position, a tripped output breaker, or an AVR/alternator issue. Treat output wiring as live until isolated.
Common causes
- Output breaker on the generator tripped
- Changeover/ATS still on mains or mid-position
- Failed AVR or brushed alternator fault
- Loose output cable after recent movement
What you can safely check
These are low-risk checks only. Do not open live electrical panels, handle refrigerant, or dismantle fuel systems. If anything feels unsafe, stop and book a verified professional.
- Confirm the changeover switch is fully on generator supply if you use one — if unsure, leave it and call a professional
- Check the breakers on the generator panel; reset once if tripped
- Test a known-good appliance on the generator's own socket if it has one
- Do not open the alternator housing
When to call a professional
- Burning smell from the control panel
- Breakers that will not stay reset
- Voltage wildly high/low if you have a meter and know how to use it safely

FAQs
Generator is on but there is no light in the house?
Check changeover position and generator breakers first. Alternator and AVR faults need a technician.
