Abstract
A charging generator having a self-diagnosis function includes a self-diagnosis circuit, a storage device and an output device. When an anomaly is detected, the charging generator with a self-diagnosis function stores data concerning at least one anomalous condition of the generator and the contents of the anomaly in the storage device, and outputs the anomalous data concerning the generator or the contents of the anomaly, which are stored in the storage device, by inputting a specific signal from the outside.
