There are also electrical faults in cars that are caused by gadgets in the cars, for instance audio and video systems, which consume too much power. As mentioned earlier, in as much as the exact trouble spot can be identified, repair of electrical faults in cars becomes a 'walk in the park.' The cost of repairing electrical faults in cars varies considerably; from just a few bucks to what can turn out to be quite a fortune. It helps to ensure that these faults are rectified by the right people, and the regular mechanics may not be the ideal people here; unless they also have certifications and experience in automobile wiring.
If the battery warning light (a light in the shape of a battery symbol) on the dashboard comes on while you're driving, that means the charging system isn't working, but the fault may lie in something other than the battery. The cause of the battery light could be a loose or corroded battery cable or other wire connecting components of the charging system, or it might be a problem with the alternator or voltage regulator. The alternator generates the power that is stored in the battery. If the alternator fails, or the accessory belt that drives the alternator is loose or broken, then you'll end up with a dead battery because the bad alternator isn't recharging the battery.
