If the battery terminals are clean and tight, then the next item to check is drive belt tension. If the belt which drives the alternator is too loose, then the alternator will not produce enough electrical current to keep up with demand. Many modern vehicles utilize a single belt which drives the alternator and other accessories. This system usually also has an automatic belt tensioner which always maintains correct tension and is not adjustable. If your vehicle uses a wide, multigrooved or so-called "Serpentine" belt to drive the alternator, then it likely also has an automatic tensioning device.
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.'
