Possible Causes
Fuel pressure too low under load, Severely clogged air filter, Overloaded generator beyond Centurion rating, Weak ignition under high cylinder pressure
How to Fix / Troubleshooting
Safety first: Open the generator main breaker so the unit can run without load during testing.
- Run no-load test: Start the generator with the main breaker open. If it runs smoothly, the issue is load-related.
- Replace air filter: Install a new Centurion air filter if dirty or oil-soaked.
- Reduce load: Temporarily disable large loads at the transfer switch or main panel and retest.
When to call a technician: If the engine still stalls with moderate load, a technician should check fuel pressure and ignition performance.
