Tell me that isn't a Battery ground cable(black) hooked up under the battery positive(red)cable on the positive side of the relay. If it is you'll have a direct short back to the battery as well as blowing out the relay, and a possible explosive situation. I hope I'm wrong.

Positive battery should be on the large left post, Neg on the large right post. small right post would be for ignition and alt, small left is ground. At least that is how mine is wired though it is of an earlier style and design.
