Just had the pool resurfaced with mini-pebble Stonescape and discovered neither pool light now works. The spa light (same light) on a separate switch works just fine. I have the Pentair Aqualight with a 250W halogen bulb. I have not used the lights since last year, so I can't verify they worked fine when they resurfaced the pool. I have ohm'd the bulb and visually inspected it from one light and it looks okay. I did get some minimal resistance on the meter. I also put the bulb back in and removed the switch by hard wiring. The light still did not come on, and I was not able to sense voltage with a voltage sensor. I have electricity at the switch box and those wires are live.
The only thing I can think of is that both lights went bad internally? Seems odd that BOTH would go bad (I have only looked at one light). New fixtures are expensive, especially if i go to LED ($500+ each).
Any ideas on something I might have missed?
Update: I'm confused looking at the electrical box. That box has two switches, one for the (2) pool lights and one for the (1) spa light. I would expect to see three (3) cables coming in for the three (3) different lights, but I only see two??? One is wired to the spa light switch (and that one works) and one is wired to the pool light switch. Also coming into the box is power from the box next to it. Just seems to me I should be seeing three (3) cables from the (3) lights??
