Electrical Fault Finding Methods
Generally, an electrical circuit is made of electrical components like lights, fuses, motors, safety switches and circuit breakers.
A wiring diagram generally helps the fault-finding procedure and will make it simple because you will identify most of the components.
Electrical problems can arise due to several issues such as corroded or loose connections, hot joins, blown fuse, faulty earth connection or melted fusible links, faulty relay or faulty sensor.
A Digital or analog meter can help you identify more faults. The device will help you check for the amperage, volts, resistance, and continuity and test the lights for load and voltage drop.
With intermittent faults, perform the pull test on wiring. The test involves wiggling the wiring to see if a fault occurs. When using the technique, you will have to narrow down a fault to its source. Intermittent wiring faults occur because of poor or loose connections and faulty wiring insulation.
