PURPOSE:To exactly judge and display the condition and causative position of anomaly during an anomalous operation by measuring the operational conditions of each apparatus belonging to an ignition system at a minimum measuring point and they by analyzing the measured data by a data processor. CONSTITUTION:The plug side secondary voltage of a distributor is taken out and then put in the peak value extraction circuit 10 through the switching circuit 18 and the discharge time extraction circuit 11. Also, primary voltage is taken out from between a contact point and an ignition coil and then put in the dwell angle extraction circuit 12, the point voltage extraction circuit 13, and the rotary trigger circuit 14. Then, data from these circuits are processed in the data processor 16 and the results are displayed on the displayer 17. |
