1-135 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. Sometimes you may run into difficulty in finding (or troubleshooting) the problem. Some hints that may help in your efforts are: Observe the equipment's operation for any and all faults Check for any defective components with your eyes and nose Analyze the cause of the failure for a possible underlying problem Classes of Overhaul Work There are five classes of equipment overhaul (A, B, C, D, and E). The class defines the type and scope of work to be done on each equipment by the overhauling activity. (Do not confuse equipment overhaul with the term regular overhaul.) CLASS A OVERHAUL.—A class A overhaul includes overhaul, repair, and/or modification; for example a modification could be an Ordnance Alteration (ORDALT), Special Program Alteration (SPALT), Ship Alteration (SHIPALT), or a field change that will sustain or improve the performance of a system or component to meet its most-recent design and technical specifications. The end product should be like new in appearance and operation. CLASS B OVERHAUL.—A class B overhaul includes overhaul and repair that will restore the performance of a system or component to its original design and technical specifications. Modifications or alterations are not done unless specified by the customer. CLASS C OVERHAUL.—A class C overhaul includes only repair work on a system or component specified by a work request or work required to correct malfunctions specified by the customer. CLASS D OVERHAUL.—A class D overhaul includes work related to the open, inspect and report type of work request. It is intended to be diagnostic in nature and may require various tests. It is normally associated with preoverhaul test and inspection (POT& I). CLASS E OVERHAUL.—A class E overhaul includes work required to incorporate all alterations and/or modifications specified for a system or component. Alterations and Modifications to Equipment Alterations and modifications to shipboard systems and equipment may take several forms. Some of these are Ship Alterations (SHIPALTS), Ordnance Alterations (ORDALTS), Special Program Alterations (SPALTS), and Air Alterations (AIRALTS). These alterations (with the exception of electronic equipment field changes) are categorized as follows:
