  If your Generac Power Systems Portable Generator runs well without any load but struggles when you connect devices, there could be a few reasons. First, a connected device might have a short circuit; try disconnecting electrical loads to resolve this. Second, the generator might be overloaded, so avoid overloading it. Finally, there could be a short circuit within the generator itself, in which case you should contact an authorized service facility.
