If you are at a customers site to repair equipment, the client may watch you, knowing they are paying for every minute you spend fault finding and repairing their equipment. Either one of those scenarios and there are more, can put plenty of pressure on you to solve the problem quickly.So, what is troubleshooting? It is practise of analyzing the behavior or operation of a faulty circuit to determine what's wrong with the circuit.

Often problems are easily diagnosed and the problem component easily visible. Other times the symptoms in addition to the faulty component can be difficult to diagnose. A defective relay with visual signs of burning should be easy to spot, whereas an intermittent problem attributable to a high resistance connection can be much harder to find.What makes an expert Troubleshooter?
