Automotive Electrical/Electronics Fundamentals (II) Hours 90

In this Electrical/Electronics course the students will study general electrical system diagnosis. Students will learn to check voltage drop on circuits, locate shorts, test grounds, test relays and circuit breakers then determine necessary action. Students will learn to diagnose and repair starting systems, charging systems as well as horn and windshield wiper systems. Students will also learn to diagnose and repair lighting circuits, sockets and controllers. Also covered in this course will be gauges, warning devices, drivers information system and sending units for gauges.
