    Why is my Doosan G100-SIIIA system undercharged?
    • E
      Elizabeth GreenSep 7, 2025
      An undercharged system in your Doosan Portable Generator may be due to a few reasons. If you've added accessories, they might be causing excessive electrical load; remove them or install a higher output alternator. Excessive engine idling can also lead to this issue; increase the engine RPM when a heavy electrical load is used. Inspect and clean any poor electrical connections on the battery, ground strap, starter, or alternator. The battery itself might be defective, so test it. Finally, the alternator could be defective, so test the charging system.

    How to start a Doosan G100-SIIIA Portable Generator if it cranks but won't start?
    • B
      Brian NguyenAug 20, 2025
      If your Doosan Portable Generator's engine cranks but doesn't start, there might be several reasons. First, ensure you're following the correct starting procedure. Check if there's fuel in the tank and that the manual shut-off valve is open. Inspect for any exhaust restrictions and correct them. The fuel filter might be plugged or full of water, so replace it or drain the water. Also, verify fuel flow at the supply pump or bleed the fuel system. If these steps don't work, the injection pump or nozzles could be faulty, requiring professional repair or replacement.
