For years, I have cleaned battery post and applied Vaseline Jelly to them before attaching cables. Never had a problem until recently.
Seems like now the Vaseline jelly will cause a hard black coating/scale to form around the post and for some reason, especially the Positive post!
The battery in one of my tractors would not start even after an overnight charging and the post and cables had no corrosion at all.
Upon removing the cables, I discovered the hard black coating on the positive post and it was really hard to scrape. I had to use a sharp knife because a wire brush would do nothing.
I reattached the cable, after cleaning it, charged the battery for one hour and it started. This was several days ago and it is still good.
I only suspect that the Vaseline jelly caused this problem, might be that it has changed, but this is my THIRD battery and two of them were in automobiles, to have this same problem.
NO MORE JELLY!
