The high-voltage supply system includes a plurality of load portions, each load portion including one or more electric devices which consume or generate electric power. The vehicle-mounted system has a plurality of diagnosis means for detecting an insulation failure. The diagnosis means has an output portion which is connected to the corresponding load portion, and outputs a diagnosis signal. The diagnosis mean has a detector detects a state signal of the system on the basis of the input of the diagnosis signal, and a diagnosis portion which determines whether or not there is an insulation failure. |
