I am on the 3rd battery for my 1999 Ford Taurus SE/6-cylinder/3.0engine/24valve overhead cam..............I just bought this 3rd one a week ago, for $75.00. I drove it about 30 miles and the dash lights went dim, headlights went dim, car just died on me and is sitting at a neighbor's house now. Some people are telling me its the Alternator. Some say its the Starter. I found a used Alternator at a junk yard for $50. But don't want to take that option? I found someone who said if I charged the battery for 4 hours and got the car to his garage, he would take it out, repair it to new, and install it, for about $100-$160 dollars???? Someone tested the Alternator last year and it was fine, running strong. Help!!! What part to I need to buy? This is my only transportation. Single Mom on disability with 2 kids, recovering from brain surgery, need to get to the doctor appointments and the store for food. Can anyone tell me which way to go? Alternator or Starter.
