Abstract

PURPOSE: To make it possible to detect the resistance easily and promptly without removing the high voltage cord as a whole from a high voltage circuit by applying a preset voltage upon the high voltage cord by power source means and by detecting the electricity.
CONSTITUTION: The high voltage output terminal of a high voltage power source 1 is connected with a current restricting resistor R1 and further with the removing point P3' of a plug cord PC, which is mounted in an engine E, from the resistor R1 through a power source cable 3. A spark discharge is effected in an spark plug PL through the cord PC. If the spacing and atmosphere of the spark plug PL are constant, the discharge is maintained by the substantially constant spark resistance. As a result, the discharge current I indicated in an ammeter 2 is varied in proportion to the resistance Rc of the cord PC so that the resistance Rc of the cord PC can be detected by detecting the current I.
