How to Fix / Troubleshooting
Safety first: Disconnect non‑essential loads before restarting.
- Measure frequency under load: Confirm that frequency drops significantly when load is applied.
- Reduce load: Shed non‑critical loads to keep total demand within the Aksa generator rating.
- Check fuel system: Replace clogged filters and ensure fuel supply is unrestricted.
- Adjust governor: Fine‑tune governor gain and droop settings per engine manual (qualified personnel only).
- Engine health check: If frequency remains low at modest load, have a technician inspect injectors and compression.
