About a month ago I noticed my pool light was not working and noticed that my GFCI was tripped. I tried to reset it but it would not reset. So I replaced the GFCI. I hooked my line power up and the my my secondary (load/Pool light) hit my
breaker and the new GFCI tripped and would not reset. So I did a little experiment and disconnected the load power and had only the line power going to the GFCI. With just line power connected it did not trip and I plugged in several
things which worked without tripping the GFCI. Anyways I have ideas of what could be wrong but I'm not 100% sure. Any help would be appreciated. The pool and equipment is 10 years old. My light equipment is FiberStars 6004 Illuminator.
