Putting out 14 volts meas the alternator is charging. After a few minutes of running, turn engine off and test battery condition. Test if you can start the engine. A bad battery would not allow you to restart.
A sticking relay is a bad relay that fails to turn off after power to the coil is disconnected. It would continue to run the components it is attached to, eg a radiator fan relay sticking would result in the radiator fan working even after the engine is turned off.
To test for power drain, you would have to disconnect the battery negative terminal and attach an ammeter in between to record the amperage. After a 10 minutes wait after hooking up the ammeter, note how many amperes is being drained. Anything more than 0.5 amp is bad.
