Ricks regulator

About a month ago my factory regulator went out and i replaced it with a ricks motorsports regulator. Well this morning i got in my rzr and when i started it i noticed the dash said lo and it was only showing 10.8 volts. I rode it around a little and the voltage never came up. Tonight i put my bad factory one back on and it now shows 13.9 volts. Has anybody else had trouble with their ricks motorsports regulator?
