Ford Repair: battery light, ford alternator, ford taurus

Question
I have a 2003 Ford Taurus with 59k miles.

my engine light has been on for 2 years and i have had different sensors replaced trying to find the problem.  About a month ago my battery light came on and the car shut down.  I was told my battery and alternator tested good but they cleaned the connections and my cam sensor needed replaced according to the scan.  My engine light was now off but two days latter my battery light came back on.  This time they replaced my alternator and the battery light came on again so all in all I had 3 alternators replaced the last one being a ford alternator.  This time my car ran for about 8 days and my engine light came back on and I had a throttle sensor replaced.  ok engine light is off but the day I picked it up my battery light came back on.  This time they replaced the battery and now I am scared to drive the car.  any ideas what could be wrong with my car

Answer
suggest a couple things, first drive it for a few more days and let me know if battery light comes back on since battery was replaced. second, when the battery light comes on, bring it to your local garage while it is on and leave it running.have them check the alternator output with the light on. if the voltage is 13.6to 14.5 volts- then the problem is most likely a poor connection at the 3 wire connector at the alternator. on another note though you may have other things going on as it had been many years since i have seen a throttle sensor replaced...
