ABSTRACT:
A testing apparatus for testing an assembly containing multiple circuits such as, for example, a control circuit for an electrically driven vehicle. The testing apparatus comprises a displaying panel member which includes a drawing illustrating a circuit assembly to be tested, an indicating element member having at least one indicating lamp which is positioned at the corresponding position of the drawing, an actuating circuit member for actuating the indicating member and a connecting member which includes a connector for electrically connecting the actuating circuit member to the assembly to be tested. In making an actual test, the corresponding portion of the circuit assembly to be tested is connected to a connector of the connector member at the same time, an external connector of the connector member is connected to the corresponding portion of the circuit assembly for electrically connecting the actuating circuit member, the indicating element member and the circuit assembly to be tested, to each other and a corresponding abnormal portion of the circuit assembly is indicated at a corresponding portion of the drawing provided in the indicating panel member, in response to a malfunction of the assembly to be tested.
