So I try and start the car tonight, and it clicks once then everything dies like the battery wasn't there. So then I clean the terminals with a wire brush and it starts just fine..
Then when I turn it off and try to restart it, same problem.
I tightened the connectors, and I know the terminals are clean and have no corrosion. So is there a problem somewhere else? The battery is a brand new duralast that was purchased 2 months ago...
