Sears Auto Center

I went to this place to have my car check, because my car will not start sometime. They told me they were going to check the battery, the alternator and starter. After checking, they were not sure what it could be. I told them that the battery is new, I just replaced it one month and 5 days ago. They told me it might be the alternator. So I asked them why the battery is fully charged, which means that the alternator is working properly charging the battery. Now they told me it must be the starter and I need a new one. I kind of had to guide you to the problem. They couldn't figure it out even with their fancy testing machines. I think those tester machines are there to mess up your car electrical components. So as I am inclined mechanically, I went home and I started removing my starter. I noticed that the positive and negative wires to the starter were completly loose: I could turn the 2 nuts with my fingers. I then tighted them up and the car will start right away and not problem until today. The car electrical components act crazy, lights flickering, ac shuting off etc before the car dies, like before I replaced the battery. I think personnally that they ruined my new battery with their test machine. So beware, don't go there for any test or repair.
