Electrical Help Please

Do you have a voltmeter in the car? If not put a voltmeter on battery with car running to check output of alternator should be at least 13 volts or more when at fast idle, about 1000 RPM. If you don't have a voltmeter, get one to do any electrical troubleshooting. Harbor Freight has one for about $5. Maybe even an Auto store as Advance auto or auto zone can check charging system for you.
