HI, so my pool light stopped working. I have the aqualink rs control. The fiber optic to led kit was installed prior to be purchasing the home. My troubleshooting so far is - relay works has 120v going to light tower, fuses good, power coming out of the transformer is 3.8V on both leads. This connects to the light wiring. Since there is voltage, I am assuming the light needs to be replaced.? rather not pull it if there's something I am missing.? If i need to pull light is it better to buy new transformer etc.. or buy the exact same replacement is I can figure it out. thanks for your help.
