QUESTION: its a 1995 softtail custom. how can you tell if its a voltage regulator or the stator? whats is the stators primary use for?

ANSWER: The stator makes AC voltage and the regulator converts it to DC volts and charges the battery.  
How do you know the battery is fully charged? Did the place you bought it from charge it for you?

QUESTION: cus when i got it i put my battery tender on and it says full

Answer
You need to charge the battery with a battery charger not a battery tender. A battery tender will not deep charge.
Install the battery after charging and make sure all the connections are clean and tight. If it still clicks then the starter relay is probably bad and needs replaced
Good luck and happy riding
