  If there's no AC output, check if the main line circuit breaker is open and reset it to ON. Also, check for any faults with the vehicle circuit breaker or fuses, resetting or replacing them as necessary. Ensure the transfer switch is set to GENERATOR, not NORMAL. When starting, hold the start switch for at least 2 seconds to flash the field. If none of these steps work, it may indicate a generator internal failure.

  If the engine cranks but doesn't start, it could be due to several reasons: the unit is out of fuel (replenish the fuel), there's a defective fuel pump (replace the fuel pump), there's an open #14 wire from the engine control board (check connections and insulation of #14 wires), the engine is flooded (wait 5-10 minutes before trying again), the spark plugs are defective (clean, re-gap, or replace the plugs), the fuel line shut-off is closed (open the fuel line shut-off), or the fuel filter is plugged (clean or replace the fuel filter).

What causes Generac Power Systems 004700-0 Inverter to continue running when the Start/Stop switch is set to Stop?
- J
  James YorkAug 25, 2025
  If the engine continues to run even when the Start/Stop switch is set to Stop, the issue could stem from a defective Start/Stop switch (replace the switch), an open/disconnected #18 wire between the Start/Stop switch and the engine control board (reconnect or close the wire), an open/disconnected #0 wire between the Start/Stop switch and the engine control board (reconnect or close the wire), or a defective engine control board (replace the control board).
