4. Demonstrate knowledge of the causes and effects from shorts, grounds, opens, and resistance problems in electrical/electronic circuits. P-2

            In auto 170 we discussed in lab the main problems that happen to electrical circuits. Though they vary in symptom most if not all of these problems are tested with the use of a multimeter. Using a multimeter and service info diagrams to know the properties of the circuits, we completed lab sheets on finding the causes of the problem. Above shown is a frayed wire, this would cause problems such as shorts to ground possibly or even low current problems due to less conductive material.
