A testing system for a ground fault detection system of an electrical system of a machine is disclosed. The testing system has a low voltage power source, the low voltage power source capable of operation that is independent from a high voltage power source of the machine. The testing system also has a variable current source that is permanently connected to a positive voltage bus or to a negative voltage bus of the electrical system of the machine, where the machine operates self-sufficiently. The testing system also has a controller connected to the variable current source. The testing system also has an input device, where the input device is connected to the controller.
