When you pop the hood and look at the complicated mechanical devices called engines, you notice right away there's plenty of wiring. In fact, the wires seem to snake around the engine in a complex configuration that makes little sense to anyone who is not a mechanic. Auto engines have plenty of electrical configurations that are critical to their smooth operation. The fact is that when a car experiences problems, it could easily be an electrical problem as much as it could be a mechanical problem. Any qualified mechanic needs to be familiar with both mechanical and electrical problems in order to be efficient at his or her job. That means a mobile car mechanic must be prepared to complete a variety of repairs including those related to the electrical systems.
When to Change Your Car's Battery. There are several signs that indicate the battery in your car is failing and needs to be replaced. Sluggish engine cranking and unusual electrical problems like flickering headlights are telltale signs of trouble, though they may also indicate problems with your car's alternator. You should also replace your battery if it is bulging or has a rotten egg smell.
