I have two Pentair lights, that look like they are 20 years old (images attached). I replaced the bulbs about 4 years ago with LEDs when they burned out, and they have worked well since. Unfortunately, this season the lights would not come on, and I noticed there was some water within the lights. I bought new gaskets, and let the lights dry out. The lights seemed to work on the deck, but after reinstalling Light 2, I noticed Light 1 was going in and out like it had a bad contact.
I checked Light 1 and the bulb came apart as I unscrewed it and there was a good amount of rust. I bought a new LED and cleaned the rust as best I could with steel wool, electric contact cleaner spray, eraser, and rubbing alcohol, but the light won't come back on, and after I pulled the bulb and cleaned Light 1, Light 2 stopped going on as well.
I noticed when I took Light 2 back out the green grounding cable had come unattached from the niche. I'm not sure if that is causing the not to come on again. That socket for Light 2 was rusty as well, but that light at least was coming on.
I called around, and quickest/most reasonable service company to come out was Leslie's, but they said I need to drain the pool past the lights for service.
So my questions are:
1. Is it possible the lights are not coming on because they detect the grounding wire has come undone?
2. Is there anything else I may be missing and should look into?
3. Am I risking damage to the vinyl liner if I drain the pool past the lights that much so they can service it (they are standard height) ?
4. Am I crazy to try to service these lights given their age and corrosion, or should I just get them replaced?
4.a. Would current Pentair lights fit in these old Pentair niche's?
