The purpose of this study is to define what circuit repairing ability is and to check improvement in learner's circuit repairing abilities by verifying conformity of learner's achievement of target goals that have been derived from headlight assignment based on circuit repairing ability that has been categorized into six sub-factors, which are preparing ability, attaching/detaching ability, circuit analyzing ability, inspecting and measuring ability, repairing (problem solving) ability and organizing ability. In order to achieve the purpose of study, degree of improvement in circuit repairing ability of learner's group was measured through experiment design and verification by group of experts. SPSS statistics program was used for statistical analysis in which average value for descriptive statistics, Cronbach ${\alpha}$ coefficient and t-test were conducted. Level of significance for t-test was p<.05. The conclusions from conducting this study are as follows. Firstly, the usage of terminology 'circuit repairing ability' pertaining to ability to repair failure of electrical devices in automobiles was confirmed to be appropriate. Secondly, the categorization of circuit repairing ability into sub-factors of preparing ability, attaching/detaching ability, circuit analyzing ability, inspecting and measuring ability, repairing (problem solving) ability and organizing ability was confirmed to be appropriate. Thirdly, field instruction on headlight assignment that has been revised according to achievement of learner's goals was confirmed to be effective in improving learner's circuit repairing abilities compared to regular training. Fourthly, field instruction on headlight assignment that has been revised according to achievement of learner's goals was confirmed to be effective in improving sub-factors of circuit repairing abilities, which are preparing ability, attaching/detaching ability, circuit analyzing ability, inspecting and measuring ability, repairing (problem solving) ability and organizing ability.

This study is focused on the development and application of automotive lighting system simulator device to help understanding of the repair and overhaul, electrical instrumentation and automotive circuit checks the contents of the automotive electrical system. The purpose of this study is to define the circuit numeracy, circuit repair preparation skills, detachable power, circuit analysis capabilities, inspection and measurement capability, and repair (problem solving) skills, through the cultivation of clean ability to increase the understanding of electrical equipment maintenance circuitry to verify the improvement of the repair. Automotive electrical device requires understanding of the invisible parts, and understanding of the various symbols and complex circuitry to measure the basic checks and repair are indispensable. This paper would likely contribute to help students to gain more interest in the fields that they feel difficult such as basic skills which necessary to cultivate a variety of electrical equipment fault diagnosis of the basic knowledge needed for electric cars practical.

현대 전자기술의 급격한 발전은 첨단 과학기술 발전에 이바지하였다. 회로카드 수십 개가 하는 역할을 IC하나로 대신하였으며 이로 인하여 전자장비의 크기는 점점 작아지고 있다. 그렇지만, 급격한 전자기술의 발전은 오래된 장비를 운용하는 곳에서는 오히려 문제점으로 발생하고 있다. 장비제작사는 기술발전에 의해 기존 제품의 대체품 없이 생산 중단함에 따라 이로 인하여 장비관리에 문제점이 발생되었고, 이는 곧 장비 가동률에 영향을 미치게 된다. 그렇기 때문에 노후 장비를 운용하는 곳에서는 자체적으로 대체 수리원 확보 또는 정비능력을 확보하여야 할 수 밖에 없다. 따라서, 본 논문에서는 전자 회로카드의 신뢰성 있는 정비 방안을 제시하고자 한다.
