So after sitting awhile the negative terminal looked pretty bad. We cleaned it all off, dielectric grease and even a new negative cable to the body. That was about 1800 miles ago. It's done this maybe 3 times now first time being when the terminal looked real bad. 2nd time about 500 miles ago so I thought maybe I had to hold the brake or something to start. Now again today. The lights do go completely out when I try to crank and she won't even turn over so I'm wondering if the 1st gen negative terminal issue can be the issue here? If it was the battery it would be more consistent. Aside from using a wire brush or sand paper to remove paint under the negative wire is there any other common issues on here for not starting randomly?
