87 warrior, battery is charged, i go to start it and the starting circuit cut off relay clicks and thats all i get wats the problem

 

The voltage is dropping too far. Check for corrosion on the battery contacts. If everything is clean and tight, then have the battery, load tested. Any good auto parts store will do that for free. If you have a voltmeter, hook it up to the battery terminals, before starting, and watch the voltage while cranking. It shouldnt drop below 10 volts while cranking.

 

Make sure your ground cable is clean & tight on both ends.
