AMS3117 ELECTRICAL I
3 Credit Hours
This course is open to students on the college level in either the freshman or sophomore year and to area high school vocational students.
AMS3117 - Electrical I (3 hrs.)
Upon successful completion of this course, the student will be able to diagnose, service, and repair automotive electrical/electronic systems, including the diagnosis, service, and repair of the general electrical system, battery, the starting, charging, and lighting systems, gages, warning devices and driver information systems, horn and wiper/washer as well as other electrical/electronic accessories.
This course is designed to help the student increase their knowledge concerning entry-level skills contained in the sequenced competencies, for success, after graduation from the Automotive Technology Program.
Upon completion of this course the student will be able to analyze and diagnose related problems specific to the automotive electrical system.
Unit Outcomes for Criterion Based Evaluation:

Maximum class size:
Based on classroom occupancy.
Course Time Frame:
The U.S. Department of Education, Higher Learning Commission and the Kansas Board of Regents define credit hour and have specific regulations that the college must follow when developing, teaching and assessing the educational aspects of the college. A credit hour is an amount of work represented in intended learning outcomes and verified by evidence of student achievement that is an institutionally-established equivalency that reasonably approximates not less than one hour of classroom or direct faculty instruction and a minimum of two hours of out-of-class student work for approximately fifteen weeks for one semester hour of credit or an equivalent amount of work over a different amount of time. The number of semester hours of credit allowed for each distance education or blended hybrid courses shall be assigned by the college based on the amount of time needed to achieve the same course outcomes in a purely face-to-face format.
