To troubleshoot a generator, identify the specific problem and the symptoms associated with it. Common steps that are followed include checking the level of fuel in the tank, inspecting the exhaust system and cleaning wire lines. Other steps include examining the oil level, changing the oil and changing the filter.
A faulty mechanical fuel gauge may cause a low fuel level in the generator tank. To rectify this, repair the fuel gauge and ensure the fuel tank is filled above the halfway mark. The exhaust system may be damaged when there is either oil or fuel leakage. To resolve this, consult the manufacturer for a detailed description on what parts need to be replaced. Repairing a damaged exhaust system may also help to fix this problem.
The next step is to check that the wire lines are not coated by rust or dirt. If this is the case, cleaning the wire lines with an air pump can help rectify this problem. Check the sensor wire to ensure that it is not faulty, since this may cause the oil level to drop below the recommended level. Filling up the oil to the recommended level, and consulting a mechanic to repair the sensor wire can help fix this.
Check to ensure that the oil has not exceeded the recommended lifespan. Replacing the oil regularly can help prevent problems with the generator. After completing these troubleshooting steps, test the generator to make sure it works. If it fails to operate properly, contact a professional technician.
