So my wife was driving a friend into town a couple of days ago and made it about a mile. She says her 05 Kia Rio seemed to power down, as if out of gas, maybe a rattling around sound.... so I towed it home. The battery was in terrible shape, leaking acid, mountains of corrosion. I've since replaced the battery, the ground cable, and both terminal connectors. I go to start it and it doesn't seem to turn all the way over. Just one loud THUNK as if a quarter turn is all she'll do.... any ideas?
