I hadnt used my pool light in forever so I tried it the other night and it wouldnt turn on, the GFI tripped as soon as I flipped the switch. Today I pulled the sealed unit (It was wet inside, so the seal was not working too well) from the pool wall and unsealed it. I dried it out, resealed it and thought I was back in business.
I turned the switch on and the GFI tripped again. So I reset the GFI and tried a couple more times with the same result. I then made a deliberate effort to jam the reset button on the GFI because it felt like because of grit in the device it was not completely re-seating. This time the light stayed on, wooohoooo success. I remounted the light in the pool and I'm back to where I was, the GFI trips when I turn the light on.
I know that circuit breakers have a tendency to trip easier if they've tripped before, sorta like it becomes esaier for the thing to trip once it has. I'm wondering if that is what is going on here. Anybody have experience with this?
