Intro and need a little help too

Hi guys, first time poster here. I’m Adam,26, and I’m from Charleston WV. My bike is a 2010 sportsman 550 touring X2 with EPS. The problem I’m having is with the power steering. The other day dad pulls the bike out of the garage to load it into the truck and everything is fine, next morning the PS won’t work. After a little research and a call to the dealer I figure it’s the voltage regulator and tried to test that from some steps I found on google(from this forum I believe). Well I’m no electrical whiz and couldn’t figure that out lol. Anyhow after having the voltage regulator unplugged a few minutes trying that we put it back together. Low and behold now the PS is working. So we figure all is well and something just needed "reset" so to speak. Well now after sitting another few days the problem is back. Voltage at the battery was throwing around 13 off and little over 14 running. Anyone have any ideas about this? Thanks fellas
