Simple Circuit Troubleshooting



Here are some websites that give some trouble shooting tips when working on an electronics project.


1. http://www.allaboutcircuits.com/vol_5/chpt_8/index.html

      This website breaks troubleshooting circuits into several sections which include questions to ask before proceeding, general troubleshooting tips, specific troubleshooting techniques, likely failures in proven systems, likely failures in unproven systems, and potential pitfalls. The questions to ask before proceeding section offers some preliminary questions to ask yourself to insure safety and timely repair. The general troubleshooting tips section gives general tips for isolating problems. The specific troubleshooting techniques section discusses swapping identical components, having knowledge of the function of the components, removing parallel components, dividing the system into sections and testing those sections, and simplifying and rebuilding or building small sections and testing them along the way. The likely failures in proven system section discusses human error, bad wire connections, and power supply problems. The likely failures in unproven systems discusses wiring problems, power supply problems, defective components, and design error. Finally, the potential pitfalls section gives common troubleshooting mistakes.

2. http://www.science-ebooks.com/Free_Ebook.htm

      This website has three main sections: Simple Resistor Network Troubleshooting, Passive Filter Circuit Troubleshooting, and Digital Troubleshooting. Within the Simple Resistor Network Troubleshooting section there are five sub-sections: Series Circuit Troubleshooting, Potentiometer Circuit Troubleshooting, Parallel Circuit Troubleshooting, Ammeter Troubleshooting, and Potentiometer and Wheatstone Bridge VBScript Simulations. Within the Passive Filter Circuit Troubleshooting there are three sub-sections: RC Low Pass Filter Troubleshooting, Simple Filters, and Complex Filters. This website is for more advanced troubleshooting. It may be useful for learning troubleshooting for repairing devices and things of that nature. This website teaches troubleshooting through text book like examples/problems.

3. http://openbookproject.net/books/socratic/output/trouble1.pdf

      This file is very much like the exam that is taken before and after one takes PHY 112. It is good because it has in depth answers to the questions and gives additional notes for teachers about each question. As the website URL suggests, this file uses the Socratic Method as a way of teaching students how to troubleshoot simple circuits.

4. http://www.ece.umd.edu/~dilli/myhumor/troubleshootessay.html

      This website is more of a reflection on one’s troubleshooting experience. It offers tips such as checking connections and using a multimeter to check voltage drops and other properties of components.
