Visual/Physical Inspection

One of the most important checks, prior to performing any diagnostic activity, is a careful visual inspection of complaint related wiring and components. This can often lead to fixing a malfunction without any further steps. Inspect battery charge level (green eye) to assure battery is not discharged. Inspect for blown fuses. Inspect all related vacuum and electrical circuits for pinches, cuts or disconnects. A good visual inspection is very important.
