This doesn't happen all the time but sometimes when I go to start my engine it doesn't start the first time around. It has that "click" noise as when the alternator goes bad but after I put the key in the off position and crank it again it starts. Scares me sometimes when I'm out somewhere and it doesn't turn over. The alternator was just replaced so I don't think that's it. What could be the cause of this? Would cleaning the battery connectors do anything? :?
