From the first steam powered coaches to today's super-cars, an automobile is a vehicle that undergoes constant changes and improvements. The first cars that were invented could barely replace the horse, were not reliable and didn't show any promising future. But people who were visionaries kept the idea alive, pressured forward thus making the car a irreplaceable part of our lives.
The test procedure is quite simple. Set the meter to read DC volts, and set the correct range if needed. Some meters will select the correct range automatically. Nearly all meters will come with instructions on how to set them to read DC volts. Next, connect the meter across the vehicle battery, positive (+) to positive (+) and negative (-) to negative (-). With the engine running at a moderate idle - say 1200 to 1500 RPM, the meter should read approximately 13.8 to 14.8 volts and be steady. If the reading is substantially outside these figures and all other items mentioned have been tested and verified good, then the alternator is likely defective.
