White stuff leaking from under voltage regulator?

I hate to revise an old thread but, If yours starts leaking replace it! mine lasted maybe 1000 miles tops. That back of mine looks like a piece of melted cheese. Its 20 dollars with tax from autozone just replace it. I had charging issues it turned out to be the regulator. if it leaks get a new one. that's just my advice. unless you like being stranded.
