A generator converts mechanical or fuel energy into electrical energy. Generators are used on a large scale to power millions of homes and other buildings across the country. On a small scale, more manageable generators are installed in homes or commercial structures to provide backup power during an emergency or power outage. There are two general types of generators: standby generators, which are permanently installed in or next to buildings and hardwired to electrical systems, and portable generators, which are intended for shorter periods of use. Does this Spark an idea?
Repairing Portable Generators
Portable generators can be impaired by a number of problems, most of which can be repaired relatively easily. Often, portable generators feature hand cranks that you must turn to start them up, similar to how you use a key to start a car. According to PowerfulPortableGenerators.com, if this crank will not budge, it is likely due to either a blown fuse (typically a 12 volt) or a dead or undercharged battery. You can simply replace the fuse, which should be located underneath an accessible control panel, and either charge or replace the battery depending on its condition (some generators will have voltage meters that show how much charge a battery has).
If you can turn the crank but it does not generate power, the above source recommends clearing out any clogs in the generator's carburetor, checking oil and fuel levels and adding more if necessary, and cleaning or replacing dirty spark plugs and air filters. If a portable generator runs but produces a disturbing sound while in use, this again is often indicative of dirty spark plugs.
Repairing Standby Generators
Standby generators are unlikely to run out of fuel, since the supply is usually piped from a local source. However, according to PowerfulPortableGenerators.com, problems with standby generators are often a result of too little oil, or oil that is too old. The above source recommends using the type of oil specified in the generator's manual, and checking oil levels often. Modern standby generators often feature illuminated displays that indicate if oil levels are too low.
Another common problem with standby generators is that their engines can overheat quite rapidly once you start them, which can produce loud, unpleasant sounds. The above source recommends turning off a generator immediately if it overheats. If the problem persists, you may have to call in a professional to make repairs.
