Possible Causes

Restricted fuel supply, Governor not responding to load, Turbocharger not producing boost, Overloaded generator beyond rating

How to Fix / Troubleshooting

Safety: Remove non‑essential loads and avoid repeated stalling which can stress engine and alternator.

  • Check load: Compare connected load to generator kW rating. Reduce load to within nameplate capacity.
  • Fuel system: Replace fuel filters and check for collapsed hoses or partially closed valves.
  • Governor operation: Observe throttle or actuator movement when load is applied. If it does not increase fuel, inspect the governor linkage or electronic actuator.
  • Turbo/air: Ensure air filter and boost hoses are intact so the Perkins engine can develop full power.
