(Ignore the mess please

)
Got into it this morning, and had a look. I checked all wires from the alternator to the starter, all seemed fine.
Then i spotted this. If you look at the picture, there is one bolt showing, with no nut or connector attached to it. This bolt is loose, and can be wobbled by hand.
The bolt itself looks very clean, as if something has not long came off it, so im hoping/guessing this is the problem.
1. Is it supposed to be like this?
2. What should attach to it?
3. Is this my problem?
Thanks alot chaps
