electronics instrumentation
Every automobile is equipped with a number of electrical instruments. The number and types of these systems and components vary significantly from vehicle model to vehicle model and year to year. The appearance of the gauge layout also varies from the auite simple (Figure 21-1) to the elaborate (Figure 21-2). No matter what it looks like, a vehicle’s instrumentation must be easy to read and give accurate information. Instrument gauges, lights and warning indicators provide valuable information to the driver concerning a vehicle’s various systems.
