The alternator provides your car with a constant source of electricity while the engine is running. Over time, the alternator can begin to fail and start causing trouble with the various electrical systems in the car. If you suspect alternator trouble, you need to check to see that is operating correctly, and is indeed the cause of the problems with your charging system. Sometimes bizarre electrical problems can be caused by a number of faults other than the alternator. It’s important to troubleshoot the system prior to replacing your alternator.

Things to look for before replacing your alternator:
• Failing belt or belt tensioner
• Voltage to the battery; little more than 12 volts with engine off & 13 – 14.5 with engine @2,000rpm
• Faulty regulator
• Engine ground strap

If still having charging problems after checking these items then it is more likely an alternator issue.
