What GENERATOR ALERT means
The Cummins Onan Quiet Diesel 3200 operator manuals list GENERATOR ALERT as operator-panel communication, PMA auxiliary power, engine speed, or inverter faults may have occurred.
Owner-safe checks
- Stop the generator.
- Record the message and whether it appeared during start or running.
Service-only work
- Electrical output, inverter, controller, stator, rotor, fuel injection, sensors, wiring, coolant-system service, fuel leaks, and generator compartment repairs belong to Cummins service or a qualified generator technician.
Safety boundary
