Ok, so I just wired up my new 12v pool light and it's not lighting. The light is wired to a pentair pool light transformer. I am getting a good 122v in. When I put my meter on the low voltage output I get the following 2 readings. 13.5v from common to 12v hot wire. 7v from ground to 12v hot wire. I get that same readings regardless if the light is connected or not. My ground connections seems fine but I would expect similar readings from common to 12v hot as I would from ground to 12v hot? I have not tested the output at the light because the different readings I am getting at the transformer have me suspecting a transformer issue.
