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.
The term of auto electrical repairs refers to the whole range of restorative and maintenance procedures carried out on a vehicle's electrical system. This is the system that is responsible for among other things, the car's lighting system, the car's automatic starting, the car's audio systems and so much more. As long as the specific parts or systems causing problems can be easily identified, such electrical repairs tend to be quite easy. The real headache however occurs when the faulty parts or systems can't be easily identified; so that the whole process has to be carried out by 'trial and error.'
