Many generator problems look alike from the outside. A generator that will not start could have a dead battery, bad fuel, a blocked filter or a failed sensor, and replacing parts without a diagnosis gets expensive. Diagnostics is the step that finds the real cause first.
A proper diagnosis usually checks:
- Battery condition and the starting circuit
- Fuel supply, fuel quality and the fuel filter
- Air filter, spark plugs and oil level
- Control board codes and safety shutdowns
- Engine performance under load
- Output voltage and the transfer switch
The result is a clear explanation of what failed and what it would take to fix it, so you can decide before work begins. Call and describe the symptoms.
