650sx wont start

I tried to start my 650 the other day, and all I get when i press the start button is a 'click' noise from the black box where the starter relay is. That seems to tell me that it's the starter relay, but I'd like to be sure before I replace it. the battery is fully charged and everything else seems to be in order. Thanks, Matt.

Before you buy.

9 out of 10 it is the relay. Check the nuts and make sure they are tight. A locked up starter or the starter gear reduction that's stuck or bad will give this same symptom, so jump the relay and see if the starter engages. Also, the cable attached to the starter can be loose along with your ground. Check all of these before replacing anything you don't need.
