Ok, I have a good battery and alternator but I still cant seem to get enough energy for my car to start. All I here when I try to crank it up is a clicking noise. My radio wont come on and my blinkers wont blink. When I cut the blinkers on it just seems to lose all power. I am getting 12 volts in the Start position from one terminal and 12 volts in the RUN position from the other. What can be my problem. i tried the battery in my friends monte carlo and it worked fine. So I dont think its the battery unless my post need cleaning. , but tell me what you guys think.

Thanks in advance,

It seems like you already know the problem. Clean the terminals and connections, and check the power connections at the starter and ground connection.
