TM 9-2320-387-24-l 1 2-39. LIGHTS TESTS I The lights tests have almost no flow chart to guide you through a problem.This is because there aren’t very many problems that can occur. The most common problems are burned-out bulbs and loose or corroded connections. Aside from bulbs and wiring, the only components are the Protective Control Box and the lights switch. If either of these is found to be faulty, you just replace the bad unit. On the following pages you will find diagrams of the major portions of the lights circuit. These are designed to help you isolate a problem without wasting too much time. 2-375
