won't start

I can't et my contour to turn over,I'vereplaced the starter, and now all it does is click when i turn the key.The battery seems to be fully charged,I even put the battery booster on it ,still won't turn over,lights,radio,wipers on while i try to turn it over, they all stay on I bench tested the new starter and it shows good,this is becoming a night mare. please help thanks Tim

I bet your starter is still bad. I see instances all the time where people take their bad alternator to autozone and it tests out fine. Seems like the logical culprit to me. I just hope you dont have a V6. Its a bitch to replace. Check the starter relay as well.
