[FONT=Verdana, sans-serif]This is the troubleshooting procedure I learned while going through Electrician's Mate "A" School, and used all through nuclear power school, years in the fleet as a nuke electrician submariner, in civilian power plants, mining, oil and gas, commercial, and even residential. It works on everything from printed circuit boards to 4 quadrant control VFD systems on the largest draglines in the world, and even residential lighting and receptacle circuits.

[FONT=Verdana, sans-serif]1. Symptom recognition. This is the action of recognizing some disorder or malfunction in electronic equipment. [/FONT]
2. Symptom elaboration. Obtaining a more detailed description of the trouble symptom is the purpose of this step.
3. Listing probable faulty functions. This step is applicable to equipment that contains more than one functional area or unit. From the information you have gathered, where could the trouble logically be located?
4. Localizing the faulty function. In this step you determine which of the functional units of the multiunit equipment is actually at fault.
5. Localizing trouble to the circuit. You will do extensive testing in this step to isolate the trouble to a specific circuit.
6. Failure analysis. This step is multipart. Here you determine which part is faulty, repair/replace the part, determine what caused the failure, return the equipment to its proper operating status, and record the necessary information in a recordkeeping book for other maintenance personnel in the future. While not a part of this step, the technician should reorder any parts used in repair of the faulty equipment.
