hi, do you have a volt meter to test something?

Customer: replied 1 year ago.
No i do not. I just replaced the battery. I tried starting it. It starts and then dies out

Thanks. It sure has all the symptoms of a faulty alternator. Because of all the electronics in the car it MUST have 14-15 volts comng out of the alternator or it wont run.
