Electrical and electronics are inseparable when it comes to troubleshooting because common and general rules applies. If you are good at troubleshooting you will be able to troubleshoot electrical electronic devices and equipments.
Why do we troubleshoot?– it is a matter of fact that equipments will fail or malfunction at one time or the other due to failure of component (s), open circuits, short circuits, mechanical injury or damages. At the time the equipment as a whole or subunit of equipment or machine in an assembly line fails, that is the equipment downtime, there would be lost of revenue, unexpected time off and the equipment may pose dangerous to the users depending on the nature of faults.
What is troubleshooting?– troubleshooting is a systematic process of analyzing the behavior and nature of a faulty circuit or equipment to determine what is wrong with the circuit or equipment with the hope of finding a solution and solving the problem. It involves identifying the defective or damaged components and repairing or replacing them. Troubleshooting could be a challenging task as some faults are intermittent in nature and put pressure on the technician while some are easily diagnosed and resolved. Mere physical observation could lead to easy diagnosis as in charred contacts of a relay or contactor; an open or shorted resistor is sometimes difficult to identify.
Where do we troubleshoot?– in most cases, troubleshooting takes place on site at its primary location but sometimes if the need arise and if possible make a loan arrangement with the owner so that the faulty equipment could be taken away to a repair workshop for proper troubleshooting but you have to consider if the equipment is portable or not.
Who is a troubleshooter? –
Troubleshooting is an expert job. Schooling, trade experience, interviewing are all necessary to becoming a successful troubleshooter. To be a troubleshooter you should:
- Have a very good understanding of how the equipment works.
- Understanding electricity and electronics.
- Know how circuits works, operations of individual components and how it all fits together.
- A good understanding of the operation of components.
- Asks questions related to the problems.
- Follow a systematic approach to logically analyse a circuit to determine what is wrong.
- Know what to do to fix the problem having identified the defective components.
- Understand how to use tools such as test instruments, schematic diagrams and service manual to identify defective components.
- Know where to get necessary parts, components and other inputs to provide a solution.
