The document outlines the tasks, knowledge, skills, and equipment required for an automotive technician to rectify an engine starting system. Specifically, it details four sub-tasks: 1) ensuring condition of starting system wiring; 2) ensuring functionality of ignition switch; 3) examining functionality of starter motor solenoid switch; and 4) examining condition of starting motor. The technician must have knowledge of starting system operation and testing procedures, and skills to test components, interpret diagrams, and conduct various electrical tests using a multimeter, hand tools, and replacement parts per the manufacturer's service manual. Personal protective equipment and fender covers must also be used.
