have the alternator checked. Answer
You can check the alternator yourself with a multi-meter/ voltmeter. Start your car and rev to about 1500 rpm, touch the meter positive lead to the b-lead on the alternator, and the meter negative lead to the alternator case, or any good ground. You should read 13 to 14 volts, anything less than about 12.5v, and you've probably got a bad set of diodes and need a new alternator.
