The answer to 'generator burning smell' is that a burning smell from a generator is typically caused by an electrical or mechanical issue that requires immediate attention. This could be due to overheating, a short circuit, or a problem with the generator's internal components.
Some common symptoms of a generator burning smell include a strong, acrid odor, visible smoke or flames, and the generator shutting down or not starting. If you notice any of these signs, it's important to turn off the generator immediately and unplug it from any power sources. Attempting to troubleshoot or repair the issue yourself is not recommended, as generators contain high-voltage electrical components that can be dangerous if not properly handled. In most cases, it's best to call a professional electrical technician to diagnose and repair the problem.
