Troubleshooting a circuit that appears to be powered from both ends r Circuit Diagram Commonly used symbols in electronic circuits are shown below in Figure 1.7. The maintenance technician should be well versed with the circuit of the system before actually starting troubleshooting. A circuit diagram is the most important document for the technician.

Troubleshooting electronic circuits can be a challenging but rewarding task. By understanding the basics of electronic circuits, using the right tools and equipment, and following a systematic approach to problem-solving, you can quickly and effectively diagnose and repair even the most complex electronic circuits. Remember to always work Learn the techniques and tools to identify and fix faulty electronic circuits from an experienced electrical engineer. Follow the steps to check the PCB, power supply, components, solder joints, and signals with multimeters, oscilloscopes, and continuity testers. Check the input voltage and voltage across the components with a multimeter using the proper multimeter technique . Often the issue may not be with the electronic components themselves but the power source or the cable leading to the components, it is always a good idea to make sure that the circuit is receiving the proper voltage and then check all the components to see if the voltages match

Practical Troubleshooting of Electronic Circuits for Engineers and ... Circuit Diagram
Continue testing sections of the circuit (or just test points within the circuit) to see if you measure the expected voltages and currents. Simplify and Rebuild. Closely related to the strategy of dividing a system into sections, this is actually a design and fabrication technique useful for new circuits, machines, or systems.
Circuit troubleshooting is the highest level of thinking required of many electrical and electronics professionals: to identify faults efficiently based on a knowledge of fundamental principles and test equipment usage. Good troubleshooters are rare, and in my opinion that has more to do with the lack of effective technical education than it Learn how to identify and fix common problems in electronic circuits with this infographic. It covers visual inspection, troubleshooting tools, power supply, components, controller, loads, and more. Most problems in an electronic circuit can be thoroughly troubleshooted and repaired by following the right steps. Prior to going on to component testing and signal tracing, always start with the fundamentals, such as visual inspection and power checks. It is possible to restore complete functionality to your circuit by solving intricate issues
