I have a problem with the electric on my car!!?

Question

I have an 2001 Mitsubishi Galant ES, 4 cylinder. I have a problem with the electric system, my battery works after testing at auto zone was said to be just fine. I would sometime have a hard time starting the car, it would click but not start and often it seems like there is no electricity going through the car. I WOULD LIKE TO KNOW IF SOMEONE COULD HELP ME FIGURE OUT WHAT COULD BE WRONG WITH THE CAR. PLEASE HELP, ANY SUGGESTIONS ARE WELCOME.

Answer 1

the battery terminals need to be cleaned most likely. you can get a terminal cleaner at parts house for less than $2. corrosion on terminals inhibit flow of power from battery to car.  

Answer 2

The thick red wire on your starter is probably loose and needs to be tightened. This wire runs from your battery. Check it out and good luck. If you need parts for it i have them.

Answer 3

it could be the starter.
