An electric vehicle driven by a D.C. series motor is disclosed in which electric power is supplied from a battery to the motor through a chopper, and in which forward-motion and backward-motion commands generated by the switch operation of a driver and a torque command from an accelerator pedal are supplied to a control device having a microprocessor, to control the chopper. The control device further includes storage means which has stored therein a trouble shooting program in addition to a program for making an ordinary running control for the electric vehicle, and is provided with a connector jack for connecting a trouble-shooting operation part to the control device. When a starting switch provided in the trouble-shooting operation part is operated in the state that the trouble-shooting operation part is connected to the control device, the control device reads out the trouble shooting program, carries out trouble shooting, and displays the results of trouble shooting on a display device provided in the trouble-shooting operation part.
