    What to do if the electric starter does not operate on my Robin America Portable Generator?
    • S
      Steven PhillipsAug 1, 2025
      If the electric starter of your Robin America Portable Generator doesn't operate, and the key switch was turned to 'START' within 2 seconds of the engine stopping, wait longer than 2 seconds before trying again. Also, if a remote controller is connected, ensure both the generator's key switch and the remote controller's switch are in the 'ON' position. If these steps don't resolve the issue, the ECU may be defective and need replacement.

    What to do if AC voltage is nominal at no-load, but load cannot be applied on Robin America RGV12100?
    • J
      Jamie PaulAug 9, 2025
      If the AC voltage of your Robin America Portable Generator is nominal at no-load, but load cannot be applied, adjust the engine speed to the rated rpm. Also, if the generator is overloaded, reduce the load to the rated output. If the appliance is faulty, replace it or remove it.

    How to fix too high or too low AC voltage on a Robin America RGV12100 Portable Generator?
    • J
      Joseph HernandezAug 17, 2025
      If the AC voltage of your Robin America Portable Generator is too high or too low, adjust the engine speed to the rated rpm. If the insulation is NG, replace the idle control unit with a new one.

    Why does the warning lamp turn on and off when the engine is stopped on my Robin America RGV12100?
    • A
      Ashley CarterAug 25, 2025
      If the warning lamp on your Robin America Portable Generator turns on and off when the engine is stopped, ensure there is fuel in the tank and that the fuel cock is open. If the fuel level is adequate, check the engine oil level and condition; add or change the engine oil if necessary.
