 Hey, I've got a 2007 Dodge Ram 2500. It's got over 212,000 miles on it. Of course, it's got the 5.7 Hemi on it, which I love. That's a great engine. But I had a problem. The battery cable ends, all that corroded real bad. And the battery was going bad. It was an old battery anyway. So I changed the battery. I changed the ends.
