I know your cable was loose but if ya put a little dielectric grease on the mating surfaces, especially the negative cable it will keep the corrosion gremlin at bay. My wife's bike suffered with this issue. You could not see the corrosion and if you did it did not seem like enough to keep the bike acting like the batt was dead. You could move the cable a hunt hair and it would crank. I put a very thin coat of the grease on the cables and have not had a issue since.
I like fried turkey, but since the wife was not here I cut the turkey in half, injected with seasoned butter and threw in the oven. My youngest liked it because he had 2nd's, 3rd's and he was still eating when I woke up 12 hours later. What I would give to have that metabolism and a good body.
