2-33. LIGHT TESTS
The Lights paragraph has 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 PCB 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.
