Can anyone let me know how to test if a voltage regulator is defective?

I found a two wire cable that was disconnected in front of the radiator the other day so I plugged it back in and the next day my battery was completely dead. I found that this two wire harness was connected to the regulator and fed the common Y/BRN wire to the battery charge coil and a BRN that ties to ground.

Not sure if I should change the regulator or just get a new battery.
