you found it...sometimes it is the simple things.....Max is right about the connections...I used to use the marine ones thinking somehow they would be better....lol.... Brass just looks good... I have a cheap terminal wire brush I use...I am sure I am leaving something behind, but, I don't care, it works and I am lazy.... These little batteries I am using sure do corrode the terminal quickly....I think I will go back to a full size in the roadster, and save the two little guys for racing....
