OPEN | A circuit is open when there is no continuity through a section of the circuit. | |
SHORT | There are two types of shorts. | |
| When a circuit contacts another circuit and causes the normal resistance to change. | |
| When a circuit contacts a ground source and grounds the circuit. |
note | Refer to How to Check TerminalHow to Check Terminal to probe or check terminal. |
