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.
Of course, in modern cars, there are battery charge indicators (in the same panel as the speedometer, fuel gauge and temperature gauge). Using these indicators, you can be able to know when your battery is developing problems, like when it is losing charge too quick, even without opening your car's bonnet. Naturally, these indicators only work for as long as the battery is at least 'basically functioning;' for it is the very same battery that powers them.
