Typical charging issues, which this sounds like, are very easy to diagnose. With your car running, take a volt meter and check your voltage at the battery. You should be reading 13 1/2 to 14 1/2 volts at idle if your alternator/voltage regulator are working correctly. Don’t sweat the exact actual voltage.
