    Why is my Ducar D2000iS Inverter generator running but not supplying power?
    • I
      Ian McdanielAug 2, 2025
      Your Ducar Inverter generator might be running but not supplying power due to several reasons: * The DC Circuit Breaker might be in the “OFF” position. If so, turn the DC Circuit Breaker to the “ON” position. * The Green AC Pilot Light Indicator might be off, in which case you should stop the engine and restart it. * There might be a poor connection or a defective cord set, so check and repair them. * The connected device could be faulty; try connecting a device that is working properly. * There could be a fault in the generator, in which case you should contact the service department.

      If your Ducar Inverter engine won't start, shuts down, or runs rough, consider these potential causes: * The 3 in 1 switch may be set to “OFF”. If so, turn the switch to “CHOKE” then pull the recoil starter. * The fuel may be stale or the unit may be out of fuel, in which case you should replace the fuel. * The spark plug wire may be disconnected from the spark plug; reconnect it. * The spark plug may be bad; clean or replace it. * There may be water in the fuel; drain the fuel tank and replace the fuel. * The engine may be overchoking; turn off the choke. * The oil level may be low; add oil. * There may be a faulty ignition, in which case you should contact our dealer.

Disconnect the device. * The generator being overloaded. See pg 17 “Don’t overload generator”. * The engine speed being too slow or a short circuit in the generator, in which case you should contact the service department.
