Replaced bad battery and now won't start

[Tom1222]

I replaced my battery in my 2003 gas Yamaha today and I sparked a wire lightly while doing so. Now the lights work, but the starter won't turn over and the backup buzzer doesn't come on in reverse either. Is there a fuse I need to replace? I found a 15 amp fuse on a cable right by the battery and it was ok, but I am wondering if there's another one and where is it located.
