4. y The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint Note the symptoms Do not begin disassembly or testing until you have narrowed down the problem area Analyze The Schematic Look up the schematic for the problem circuit Deter mine how the circuit is supposed to work by tracing the current paths from the power feed through the circuit components to ground If several circuits fail at the same time the fuse or ground is a likely cause Based on the symptoms and your understanding of the circuit operation identify one or more possible causes of the problem isolate The Problem By Testing The Circuit Make circuit tests to check the diagnosis you made in step 2 Keep in mind that a logical simple procedure is the key to efficient troubleshooting Test for the most likely cause of failure first Try to make tests at points that are easily accessible 16 8 Fix The Problem Once the specific problem is identified make the repair Be sure to use proper tools and safe proce dures Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you ve fixed the entire problem If the problem was a blown fuse be sure to test all of the circuits on that fuse Make sure no new problems turn up and the original problem does not recur
