I have full power, battery etc but when I turn the key all I get is a clicking sound. Is that my alternator?

Clicking? Or nothing at all? If you hear a click, then either the battery is weak, or the starter, possibly bad battery cable connections, check and clean both ends of BOTH cables! Dissconnect negative(-) first, and put it on last! If no click the starter relay is no good! Try a jump start. Attach a voltmeter to the battery while cranking, if volts drop below 10, battery is no good.
